The Complete Herb Guide: How to Grow, Harvest and Preserve 14 Kitchen Herbs

close up of a thriving bright green basil plant

The short answer: most kitchen herbs want full sun, get cut hardest in the morning, and keep best frozen rather than dried. Woody herbs like rosemary, sage and thyme freeze whole on the stem. Soft herbs like basil, parsley and cilantro freeze chopped under olive oil. Open any herb below for how we grow it, when to cut it, and the best way to keep it.

Every September the porch planter gets away from me. The rosemary is a hedge, the sage has gone wide, and the basil is one cold night away from being done for the year. Throwing it on the compost pile feels like a waste, because it is one.

So this is the whole thing in one place. Fourteen herbs, one at a time, plus everything we have learned about harvesting and putting them up. Tap the herb you are standing in front of.

The herbs, one at a time

Basil annual · soft herb
close up of a thriving bright green basil plant

The one everybody plants and the one everybody cuts wrong. Genovese is the pesto basil, Thai basil holds up to heat in a stir fry, and lemon basil is worth a pot of its own.

The part nobody tells you

Stick a cut basil stem in a glass of water on the windowsill and it will grow roots in about a week. One bunch from the grocery store, the kind you buy for four dollars in March, becomes a whole summer of plants for free. Strip the lower leaves, change the water every couple of days, and pot it up when the roots are an inch long.

Where it wants to live

Full sun and warm soil. Do not set it out until nights are reliably above fifty degrees. Italian types can reach three feet, so give them room.

Varieties worth growing

Genovese is the pesto basil and the one to grow if you only grow one. Sweet Italian large leaf gives you more per plant. Thai basil holds its flavor in a hot pan, which regular basil does not. Lemon basil is worth a pot of its own for fish and shortbread. Dark Opal and other purple basils make a stunning pink vinegar.

How to cut it

Start when the plant is six inches tall or has six leaves. Cut just above a node, the point where a pair of leaves meets the stem, and the plant branches from there. Take from the top first, never more than a third at a time, and pinch off flower buds the day you see them.

How to keep it

Chop it and freeze it under olive oil in an ice cube tray. Do not dry basil. It loses almost everything.

In the kitchen

Pesto, caprese, and torn over a pizza after it comes out of the oven, never before. Basil lemonade. Compound butter rolled in parchment and frozen. Stirred into tomato sauce off the heat so it keeps its perfume.

What goes wrong

Cold, long before frost. Basil takes chilling injury once nights drop below about fifty degrees and the leaves go black at the edges. When you see a fifty degree night in the forecast, cut all of it.

Chives hardy perennial · soft herb
A clump of chives with hollow green leaves growing in a raised bed, one purple flower bud showing

The first green thing up in spring and the last one standing in fall. The purple flowers are edible and make a beautiful pink vinegar.

The part nobody tells you

Chives are the first thing up in our garden every spring, often pushing through the last of the cold while everything else is still asleep. Old gardeners plant them at the base of roses and apple trees because the onion smell confuses aphids. Whether or not that works, you get a free crop of pink pompoms out of the deal.

Where it wants to live

Full sun, about a foot tall, forms a clump that gets fatter every year. Dig and divide every three or four years or the middle dies out.

Varieties worth growing

Common chives are the thin round ones with purple pompom flowers. Garlic chives are flat leaved with white flowers in late summer, taste faintly of garlic, and self sow hard enough that you will be pulling seedlings for years.

How to cut it

Snip individual leaves down at the base rather than shearing across the top. A haircut leaves you a clump of brown stubs for the rest of the season.

How to keep it

Chop and freeze loose on a sheet pan, then bag, or freeze in water cubes. Dried chives are hay.

In the kitchen

Anything with eggs or potatoes. Snipped raw over soup, into sour cream, folded into butter. Do not cook them long, heat takes the flavor straight out. Pull the blossoms apart over a salad, or steep them in white vinegar for two weeks and get a bright pink chive vinegar.

What goes wrong

Very little. If it flowers and you want leaves, cut the flower stems out at the base.

Cilantro cool season annual · soft herb

Two crops in one plant. The leaf is cilantro, the seed is coriander, and they taste nothing alike.

The part nobody tells you

If cilantro tastes like soap to you, that is not pickiness, it is your genes. A variation in a smell receptor gene called OR6A2 makes some people read cilantro’s aldehydes the same way they read dish soap. Depending on ancestry, somewhere between four and fourteen percent of people have it. You are not being difficult and you will probably never like it.

Where it wants to live

Full sun to part shade and cool weather. Direct sow, because it resents being moved. Sow a short row every two or three weeks in spring and again from late August on.

Varieties worth growing

Look for slow bolt types, which buy you a few extra weeks. Calypso, Santo and Leisure are the common ones. Delfino has feathery leaves that look nothing like cilantro and take longer to bolt.

How to cut it

Take outer leaves while the plant is low and bushy. Once it starts to stretch upward it is on its way to seed, so cut the whole plant at soil line and use it.

How to keep it

Freeze it chopped under oil. Never dry it. Or let the bolted plants finish and collect the round seeds for coriander, which stores beautifully.

In the kitchen

Salsa, tacos, curries, pho, and always added at the very end because heat destroys it. The seed is a different ingredient entirely. Toast coriander seed in a dry pan and grind it for curry, chili and spice rubs.

What goes wrong

Heat. It bolts the second summer arrives, and nothing stops that. Plant it early, plant it again in fall, and make peace with the summer gap.

Dill cool season annual · soft herb
Close-up of feathery blue-green dill foliage growing in the garden

Grow it for the fronds, the seed heads, and the swallowtail caterpillars that will show up and eat some of it. Plant extra and let them have their share.

The part nobody tells you

Plant more dill than you need and you will get butterflies. Black swallowtails lay their eggs on dill, fennel and parsley, and the caterpillars are the striped green ones that look like they were designed by committee. They will strip a plant. Let them. That is the trade, and it is a good one.

Where it wants to live

Full sun, direct sown where it will stay, because the taproot hates transplanting. It gets tall, so put it at the back or stake it.

Varieties worth growing

Bouquet is the standard and gives generous seed heads for pickling. Fernleaf stays compact and does well in a pot. Mammoth gets tall and is grown for seed. Dukat is the leafy one if you want fronds more than heads.

How to cut it

Snip the young feathery leaves any time. For pickling, cut whole heads just as the flowers open and the seeds are still green.

How to keep it

Freeze the fronds, chopped or whole. Let seed heads dry on the stem in a paper bag and store the seed in a jar.

In the kitchen

Pickles first, obviously. Then potato salad, salmon, cucumbers in sour cream, yogurt sauces and homemade ranch. The seed goes in pickling brine and rye bread.

What goes wrong

It runs to seed quickly in heat. Succession sow, and let a few plants self seed so you get volunteers next spring.

Lavender perennial shrub · woody herb
Spanish lavender in bloom, showing the purple rabbit ear bracts on top of each flower spike

Beautiful, useful, and the herb most likely to die on you in the South. Not because of cold. Because of wet.

The part nobody tells you

Lavender is in the mint family, same as basil, rosemary and sage. And the oils peak just before the flowers open all the way, which is why commercial fields harvest at bud stage and why the bundle you cut too late never smells as strong as the one you cut early.

Where it wants to live

Full sun, lean soil, and sharp drainage. A raised bed or a gravel mound beats good garden soil every time. English lavenders handle cold best, Spanish and French types handle heat and humidity better.

Varieties worth growing

English lavenders are the culinary ones and the most cold hardy. Munstead and Hidcote are the classics. Spanish lavender handles our heat and humidity better but is not what you want in food. Phenomenal and Provence are the ones people here have the best luck keeping alive through a wet winter.

How to cut it

Cut flower stems just as the lowest buds on the spike begin to open. Shape the plant after flowering, but never cut back into bare old wood, which will not resprout.

How to keep it

Air dry it. Bundle the stems tightly, hang them out of direct sun, and strip the buds into a jar once they are crisp.

In the kitchen

Use English lavender and use less than you think. It turns soapy fast. Shortbread, lemonade, honey, and sugar left in a jar with a few buds. Everything else it does is sachets, wreaths and making a room smell like summer.

What goes wrong

Rich soil, heavy mulch, and overhead watering. Give it grit and neglect and it will outlive you.

Lemon balm hardy perennial · soft herb
A thick stand of lemon balm with bright green scalloped leaves growing along a wooden fence

Mint family, lemon scented, and the easiest tea herb there is. Crush a leaf on your way past it and you will plant more.

The part nobody tells you

Melissa, the plant’s botanical name, is Greek for honeybee. Beekeepers going back to the Romans rubbed lemon balm inside an empty hive to make a swarm want to move in, and crushed it on their hands before working the bees. Walk past a flowering patch on a warm afternoon and you will hear it before you see it.

Where it wants to live

Sun or part shade, about a foot and a half tall, not picky about soil.

Varieties worth growing

Plain Melissa officinalis is all most people need. Aurea is variegated and prettier in a pot. Lemonella has a stronger lemon note if you are growing it mainly for tea.

How to cut it

Shear the whole plant back by a third whenever it gets leggy. It comes back fast and the new growth is the best of it.

How to keep it

Dry it for tea, which it takes better than most soft herbs, or freeze it in water cubes for iced tea and lemonade.

In the kitchen

Tea, hot or iced, which is what it is best at. Lemonade. Tossed through a fruit salad. Steeped in honey or made into a simple syrup that keeps a week in the refrigerator.

What goes wrong

It spreads by root and self sows hard. Put it in a container or a bed you are willing to hand over.

Marjoram tender perennial, grown as an annual · woody herb

Oregano’s gentler cousin. Sweeter, softer, and better than oregano in anything with eggs or cream.

The part nobody tells you

The genus name Origanum comes from two Greek words meaning mountain and joy. It was woven into wedding crowns and planted on graves, the same herb for the happiest day and the hardest one. For something most people only meet in a jar of Italian seasoning, it has carried a lot.

Where it wants to live

Full sun, six to nine inches tall, very happy in a pot. It is hardy only to about zone 9, so in most of the country, mine included, it will not survive winter in the ground. Grow it in a container and bring it in.

Varieties worth growing

Sweet marjoram is the real thing and the one worth growing. What is sold as Italian or hardy marjoram is usually a marjoram and oregano cross, tougher but coarser.

How to cut it

Harvest before it flowers, when the flavor is strongest. Cut stems rather than picking leaves.

How to keep it

It dries well, unusual for something this tender, and it also freezes fine on the stem.

In the kitchen

It belongs anywhere oregano would be too loud. Eggs, cream sauces, mushrooms, poultry, sausage. Add it near the end of cooking, because its flavor is delicate and cooks off.

What goes wrong

People plant it expecting oregano’s toughness. It is not that plant. Treat it like an annual and you will not be disappointed.

Mint hardy perennial · soft herb
A black swallowtail butterfly resting on spearmint leaves in the garden at Sweet BombDiggity Farms

Spearmint for tea and juleps, peppermint for anything sweet, chocolate mint because it is fun. They all behave the same way, which is badly.

The part nobody tells you

Mint does not actually cool anything. Menthol latches onto a nerve receptor called TRPM8, which is the exact same receptor that fires when you touch something cold. Your mouth is not being chilled, it is being told it has been. It is one of the few times you can catch your own senses lying to you on purpose.

Where it wants to live

Part shade suits it better than full sun, and it is not fussy about soil. Plant it in a pot, or in a bed with an edge it cannot cross, or plan on mint forever.

Varieties worth growing

Spearmint is the tea and julep mint and the one most people mean. Peppermint is stronger and better with chocolate and anything sweet. Chocolate mint really does smell like it. Apple mint is fuzzy and mild. Whatever you plant, plant one, because they all spread the same way.

How to cut it

Cut stems often and hard. Frequent harvest keeps it from flowering, and flowering is when the flavor drops off.

How to keep it

Water cubes for tea and drinks. It also dries better than most soft herbs if the leaves are for tea rather than cooking.

In the kitchen

Iced tea, juleps, mojitos. Tabbouleh, where it belongs alongside the parsley. Peas, lamb, and a yogurt sauce with cucumber. Muddle it rather than chopping when it is going into a drink.

What goes wrong

It runs underground. One plant becomes a colony in two seasons. Contain it from the start.

Oregano hardy perennial · woody herb
A wide mat of grey-green oregano sprawling over the edge of a raised bed with rosemary behind it

The one herb that is genuinely better dried than fresh. Greek oregano is the one with the punch. Common oregano can be almost flavorless, so buy a plant you have smelled.

The part nobody tells you

Oregano tastes better when you are mean to it. The compound that gives Greek oregano its bite, carvacrol, builds up when the plant is stressed by sun and drought. Rich soil and regular water give you a big lush plant that tastes like nothing. The sad looking one wedged in gravel at the end of the bed is the one you want.

Where it wants to live

Full sun, dry feet, up to two feet across. It is tough, it is hardy, and it will come back bigger every year.

Varieties worth growing

Greek oregano is the one with the punch, and it is worth seeking out by name because plain Origanum vulgare can be almost flavorless. Smell a leaf before you buy the plant. Syrian oregano is what goes in real zaatar. Golden oregano is pretty and weak.

How to cut it

Cut stems right before the flower buds open, which is when the oil content peaks. You can take a hard cut mid summer and get a second flush.

How to keep it

Dry it. Hang bundles, strip the leaves when crisp, and store them whole in a jar. Crush between your fingers as you cook.

In the kitchen

Tomato sauce, pizza, roasted vegetables, Greek dressing, marinades for lamb and chicken. This is the herb you add early rather than late, and dried rather than fresh, which is backwards from everything else in this guide.

What goes wrong

Rich soil and too much water make a big plant with weak flavor. Keep it lean.

Parsley biennial, grown as an annual · soft herb
Large bunches of flat-leaf Italian parsley tied with string on a market stall

Flat leaf Italian for cooking, curly for the plate. Not a garnish, an ingredient. A whole cup of chopped parsley is what makes tabbouleh taste like anything.

The part nobody tells you

Chewing parsley after garlic actually works, and it is not just masking. And here is the one that surprises people: parsley is a biennial, so the second spring it shoots up, flowers and dies, doing exactly what it was built to do. The Greeks tied it to death and rebirth for that reason, and then put it on the plate anyway.

Where it wants to live

Light shade, steady moisture, deeper soil than you would think. Seed is famously slow, two to four weeks, so do not give up on it.

Varieties worth growing

Italian flat leaf is the cooking parsley and the one to grow. Curly holds up better as a garnish and has more bite raw. Hamburg parsley is grown for its parsnip like root, which is worth knowing about even if you never plant it.

How to cut it

Take the outer stems at the base and let the center keep producing. It handles frost and will often hold into winter.

How to keep it

Chop and freeze, in oil for cooking or water for soups. Drying is a waste of it.

In the kitchen

Tabbouleh, where it is the main ingredient and not a garnish. Gremolata with lemon zest and garlic over braised meat. Chimichurri. Stems into the stock pot. A handful chopped over almost anything at the end to wake it up.

What goes wrong

The second year it bolts and sets seed, because it is a biennial doing exactly what it is supposed to do. Start new plants every year.

Rosemary evergreen shrub · woody herb
A row of rosemary plants growing in a wooden raised bed in full sun

A shrub that happens to be a seasoning. Given a spot it likes, it becomes a permanent part of the garden and you cut from it in February.

The part nobody tells you

Rosemary is not Rosmarinus anymore. In 2017 botanists looked hard at the DNA and moved it into Salvia, the sage genus, so the correct name is now Salvia rosmarinus. Rosemary is a sage. Every plant tag and cookbook is still catching up, and you can start an argument at a garden club with it.

Where it wants to live

Full sun and drainage above all. It can pass four feet. Winter hardiness is the real question with rosemary. It holds to about zone 7, which is where I am, and a hard winter takes unprotected plants even here, so look for Arp or Hill Hardy, plant it against a south wall, and skip the heavy mulch.

Varieties worth growing

In zone 7 the variety is the whole ballgame. Arp and Hill Hardy are the ones bred to take our winters. Tuscan Blue is a beautiful upright if you are willing to lose it in a bad year. Prostratus trails over a wall or a pot edge.

How to cut it

Cut soft green tips any time of year. Do not cut back into old bare wood, because it will not push new growth from it.

How to keep it

Freeze whole sprigs flat in a bag. It also dries well. Frozen keeps more of the oils, dried is easier to reach for.

In the kitchen

Potatoes, roast chicken, lamb, focaccia. Pushed into a loaf of bread before baking. Infused into oil or into a simple syrup for lemonade. And rosemary salt, which uses up an armful at a time.

What goes wrong

Wet roots in winter, which kills more rosemary than cold does. Raised, gritty, and on the dry side.

Make more of it

Rosemary roots from cuttings more willingly than almost anything else out there, and one plant will give you a whole row. We walk through it in Turning One Into Many, our guide to an endless rosemary garden.

Sage evergreen perennial · woody herb
Close-up of a mature common sage plant with large velvety grey-green leaves

Holds its leaves through our winters, which means fresh sage for Thanksgiving straight off the plant. Purple and tricolor sages are just as edible as plain green.

The part nobody tells you

Salvia comes from the Latin salvere, to be saved or to be well, which is a lot of name for a plant that mostly ends up in Thanksgiving dressing. Do this once: drop whole sage leaves into hot butter for about thirty seconds until they stop sizzling, lift them onto a paper towel and salt them. They go glassy and crisp, like a leaf shaped potato chip, and they will not make it to the table.

Where it wants to live

Full sun and drainage, a small shrub about two feet across. It gets woody and sparse after three or four years, so start a replacement from a cutting before you need it.

Varieties worth growing

Common garden sage is the workhorse. Berggarten has broader, rounder leaves and stays tidier. Purple and tricolor sages are just as edible and look better in a bed. Pineapple sage is a different plant for a different job, tea and hummingbirds, not dressing.

How to cut it

Take leaves or short stems any time. Give it a shaping cut in spring, into green growth rather than bare wood.

How to keep it

Freeze whole leaves or sprigs flat. It is also one of the few herbs that oven dries well.

In the kitchen

Thanksgiving dressing, and it is worth growing for that alone. Brown butter with squash ravioli. Sausage, pork, white beans. Whole leaves fried crisp in butter for about thirty seconds and salted.

What goes wrong

Humidity and crowding bring on mildew. Give it air on all sides.

Tarragon perennial · soft herb

French tarragon is the one you want, the anise note behind bearnaise and a good chicken. It sets no viable seed, so anything sold as tarragon seed is the Russian kind, which tastes like grass.

The part nobody tells you

French tarragon almost never flowers, and when it does the seed is sterile. So there is no such thing as growing it from seed. Every French tarragon plant alive is a cutting or a division of another one, going back and back. The plant in your garden is, in a real sense, a piece of the same plant everybody else is growing.

Where it wants to live

Full sun and excellent drainage. It struggles with Southern summers, so give it afternoon shade and never let it sit wet. Many people here grow Mexican mint marigold instead, which takes the heat and tastes close enough.

Varieties worth growing

French tarragon is the only one worth growing and it is sold only as a plant, never as seed, because it does not set viable seed. Anything labeled tarragon seed is Russian tarragon, which is coarse and tastes like grass. Mexican mint marigold is the heat tolerant stand in most Southern gardeners end up with.

How to cut it

Cut stems in the top third through the season. Cut it back hard in late summer for tender regrowth.

How to keep it

Freezing beats drying, which loses it almost entirely. Tarragon vinegar holds the flavor longest of anything.

In the kitchen

Bearnaise. Chicken, eggs, green beans, fish. A vinaigrette built on tarragon vinegar. Its anise note goes further than you expect, so start with less.

What goes wrong

Buying the wrong plant. Always buy French tarragon as a plant, never as seed, and crush a leaf before you pay for it.

Thyme hardy evergreen perennial · woody herb

Tiny leaves, enormous range, and it goes in nearly everything. English thyme for cooking, lemon thyme for fish and shortbread, creeping thyme for between the pavers.

The part nobody tells you

Thymol, the oil that gives thyme its smell, is one of the active ingredients in Listerine and turns up in a lot of natural cleaners. The Greeks burned thyme as incense and handed it to soldiers as a symbol of courage, which is a big job for a plant with leaves the size of a grain of rice.

Where it wants to live

Full sun and gritty soil. Forms range from flat groundcover to a foot tall. It is hardy and mostly evergreen, so you can cut in January.

Varieties worth growing

English or common thyme is the cooking one. French thyme is finer leaved and sweeter. Lemon thyme is worth a separate plant for fish and shortbread. Creeping and woolly thymes are for walking on between pavers, not for the kitchen.

How to cut it

Cut stems with scissors rather than pulling, which lifts the shallow roots. Shear it lightly after it flowers to keep it from going woody in the middle.

How to keep it

Freeze whole sprigs and strip the leaves off frozen with your thumb. It dries well too.

In the kitchen

Stock, braises, beans, mushrooms, roast chicken. It is the herb that goes in early and cooks all afternoon. Lemon thyme in shortbread, or under the skin of a fish before it goes in the oven.

What goes wrong

Wet soil and old age. Every few years, replace the woody centers with cuttings, which root easily.

Cut early in the day

Harvest in the morning, after the dew dries and before the sun gets high. That is when the oils in the leaves are strongest, and the oils are the whole point.

Never take more than a third of a plant at once. That is the rule that keeps a plant producing instead of sulking.

Woody or soft decides everything

This is the part that changes how you put herbs up, and almost nobody explains it.

Woody herbs have tough stems and stiff, low moisture leaves. Rosemary, sage, thyme, oregano, marjoram, lavender. These hold up to both freezing and drying.

Soft herbs have tender green stems and high moisture leaves. Basil, parsley, cilantro, dill, chives, tarragon, mint, lemon balm. These go limp and brown when dried and lose most of their character. Freezing is the better answer, and for the most delicate ones, freezing in fat is better still.

Freezing woody herbs

The simplest thing in this whole guide.

  1. Cut whole sprigs and rinse them.
  2. Dry them completely. Water left on the leaves turns into freezer burn.
  3. Lay the sprigs flat in a freezer bag in a single layer, or wrap a few sprigs in freezer wrap first and then bag them.
  4. Press all the air out, seal, and label with the herb and the date.

Use them straight from frozen. Crumble rosemary over potatoes, drop a whole sage sprig into a pan of browning butter, strip frozen thyme leaves off the stem with your thumb. No thawing, no chopping.

Freezing soft herbs under olive oil

This is what we do with the basil, and it is the method that made me stop drying it altogether.

  1. Harvest early in the day and rinse the leaves gently.
  2. Pat them completely dry.
  3. Chop finely, or pulse in a food processor with a little olive oil. The oil is what protects the color and the flavor.
  4. Spoon the herbs into an ice cube tray, filling each compartment about halfway.
  5. Top with olive oil until the herbs are fully covered. Any leaf poking above the oil will darken.
  6. Freeze solid, then transfer the cubes to a labeled freezer bag or container.

One cube is roughly two tablespoons of chopped herb, already carrying the fat it needs to bloom in a hot pan.

Keep them frozen. Herbs in oil have no acidity protecting them, so an herb and oil mixture is only safe frozen. It never sits on the counter and it never lives in the pantry. Freeze it, use it from frozen, and you are fine.

Freezing in plain water

For chives, mint, lemon balm and parsley headed for soups and teas, water works fine and costs you nothing. Chop, pack into the tray, cover with water, freeze, and bag.

Water cubes are better for anything going into liquid. Oil cubes are better for anything hitting a hot pan.

When drying is the right call

Drying earns its keep on the woody herbs, and on oregano it is not just acceptable, it is better. Bundle the stems tightly, because the stems shrink as they dry and slip right out of a loose tie. Hang them out of direct sun, then strip the leaves into an airtight jar.

Dried herbs hold their flavor about three months in a cupboard and up to a year in the refrigerator or freezer. Store the leaves whole and crush them as you use them.

Skip drying for basil, cilantro, chives, dill and tarragon. You will not like what comes back.

Do the basil first

Basil is tropical, and it does not wait for frost. It starts taking chilling injury once nighttime temperatures drop below about fifty degrees, which in East Tennessee happens weeks before the first freeze. The leaves go dark and translucent and turn black at the edges, and there is no bringing them back.

So when the forecast shows a fifty degree night, that is your signal. Cut the basil, all of it, and deal with it in the kitchen. The rosemary, sage and thyme will still be out there in December.

Want to see the trim? Here is how we cut basil just above a node so it branches out and keeps producing all summer. Never take more than a third of the plant at once, and pinch off flower buds as soon as they show up.

Basil is good for more than dinner, too. Steep the leaves in white vinegar for a few weeks for a quick basil vinegar for dressings, or simmer a handful with lemon slices and cinnamon sticks and the whole house smells wonderful.

A few questions we get asked

How long do frozen herbs last?

About a year at good quality. They are safe indefinitely at zero degrees, but the flavor fades after that first year.

Do I need to blanch herbs before freezing?

No. Culinary herbs go straight into the freezer washed and dried. Blanching is for vegetables.

Which herbs come back every year?

That depends on how cold your winter gets, so here is the whole shelf by cold tolerance rather than by my garden. I am in zone 7B in East Tennessee, but these numbers travel.

HerbHardy to aboutWhat that means
ChivesZone 3Comes back almost anywhere
MintZone 3Comes back everywhere, keep it in a pot
OreganoZone 4Reliable perennial in most of the country
SageZone 4Comes back, but bare in spring, so preserve in fall
ThymeZone 4Reliable, wants sharp drainage
Tarragon (French)Zone 4Comes back, dies down completely
Lemon balmZone 4Comes back, and spreads
Lavender (English)Zone 5Needs drainage more than it needs warmth
ParsleyZone 5Biennial, better replanted each year
RosemaryZone 7The fussy one. Zone 6 with Arp or Hill Hardy and a sheltered spot. Colder, grow it in a pot and bring it in
MarjoramZone 9Treated as an annual nearly everywhere
BasilAnnualDone at the first frost, no exceptions
CilantroAnnualCool season, bolts in heat, often reseeds
DillAnnualReseeds itself readily

If you do not know your zone, the USDA map at planthardiness.ars.usda.gov gives it to you from your zip code. Outside the United States the numbers will not match your system, but your average winter low will tell you the same thing.

One rule holds everywhere: a perennial herb that dies back to the ground comes up in spring with nothing on it. If you want it in your kitchen this winter, cut and preserve it now, while the plant is still full.

Why did my frozen herbs turn brown?

Almost always water left on the leaves, air left in the bag, or leaves sitting above the oil line. Dry them thoroughly, press the air out, and keep everything submerged.

Is it safe to store herbs in olive oil?

Only frozen. Oil is not acidic and offers no protection against botulism, so herb and oil mixtures do not belong at room temperature or in the refrigerator for long. Freeze them and use them from frozen.

Can I use frozen herbs as a garnish?

No. They go limp as they thaw. Frozen herbs are for cooking, not for the top of the plate.

How much can I cut at once without hurting the plant?

Up to a third of the plant. Take from the top, cut above a leaf node, and water afterward.

My herb is flowering. Is it ruined?

Not ruined, but flavor drops once a plant flowers, because the plant is putting its energy into seed. Pinch buds off as they appear on basil, mint and marjoram. On oregano, cut the whole plant back just before the buds open, which is when its oils peak.

Can I mix herbs in one cube?

Yes, and it is a good idea if you cook the same dishes often. A rosemary, sage and thyme cube is a whole pan of roasted vegetables waiting to happen.

What about the woody stems, can I use those?

Do not throw out rosemary and thyme stems. Freeze them in a separate bag and drop them into stock, or use stripped rosemary stems as skewers on the grill.

Which herbs can I grow in a pot on the porch?

Basil, chives, parsley, thyme, marjoram and mint all do well in containers, and mint should be in one. Rosemary and sage will live in a pot for a few years but want to be in the ground eventually. Dill and cilantro resent transplanting, so sow them directly into the pot they will finish in.

Looking for something to do with the dried ones? Our homemade rosemary infused herb seasoning salt uses up a lot of rosemary and makes a good gift.
