Bay leaves come from the bay laurel (Laurus nobilis), an aromatic evergreen from the Mediterranean that has been grown for kitchens and gardens for thousands of years. Most cooks meet it as a dried leaf dropped into a pot of soup or stew, but the plant itself is a handsome, glossy-leaved shrub or small tree that earns its keep year round. Grow one well and you will have an ornamental specimen, a clippable topiary, and a lifetime supply of fresh and dried leaves from a single plant. Bay is slow, forgiving, and long-lived, which makes it one of the easiest woody herbs to keep going for decades. This guide walks through where bay laurel will grow, how to plant and care for it in the ground or in a pot, how to overwinter it in cold regions, how to propagate new plants, and how to harvest, dry, and store leaves with the most flavor.
Bay laurel is a slow-growing Mediterranean evergreen, not the toxic laurels it is confused with
Bay laurel belongs to the laurel family, Lauraceae, which also gives us cinnamon, avocado, and camphor. It is a woody evergreen perennial that can grow as a multi-stemmed shrub or a single-trunked tree. Left alone in a warm climate and good ground, a mature plant can eventually reach 20 to 40 feet or more, but it grows only about 10 to 12 inches a year, so it takes many years to get there and is easily kept smaller with pruning. The leaves are leathery, oval, and dark green with slightly wavy edges, usually 2 to 4 inches long, and new growth often emerges a purplish bronze before hardening to deep green.
The plant is dioecious, meaning male and female flowers appear on separate plants. The small creamy-yellow spring flowers are not showy, and the dark berries that follow on female plants are not used in cooking. Since nurseries rarely label plants by sex and most gardeners grow bay purely for foliage, this matters little for the home grower.
One distinction does matter a great deal: true bay laurel is the only common “laurel” whose leaves you should eat. Cherry laurel (Prunus laurocerasus), Portuguese laurel (Prunus lusitanica), mountain laurel (Kalmia), and the so-called California bay (Umbellularia californica) are all different plants, and several of them are poisonous. Cherry laurel and Portuguese laurel are widely sold as hedging and have toxic foliage, while California bay has a harsh, overpowering flavor and is not a safe culinary substitute. When you buy, confirm the botanical name reads Laurus nobilis. The leaves of true bay are aromatic when crushed, with a warm, slightly spicy nutmeg-and-clove scent that the look-alikes do not share.
Bay is reliably hardy outdoors in USDA zones 8 to 10 and grown in pots everywhere colder
Bay laurel is a tender evergreen rather than a tropical plant, and its cold tolerance is the single factor that decides how you grow it. In the ground, established plants are hardy to roughly USDA zone 8, surviving brief dips to about 20 to 25 degrees Fahrenheit (around minus 5 degrees Celsius). That makes zones 8 through 10 the comfortable range for growing bay permanently in the landscape as a shrub, hedge, or small tree.
Hardiness improves once a plant is settled. Bay planted directly in the ground is noticeably tougher than the same plant in a pot, because the roots run deeper and the surrounding soil insulates them. In zone 8, a wall-sheltered, well-established bay usually shrugs off normal winters, while a young or container plant in the same garden may suffer leaf burn. Cold winds do as much damage as cold air, scorching foliage brown or black even when temperatures are not truly freezing.
In zone 7 and colder, treat bay as a container plant that lives outdoors in the warm months and comes inside before hard frost. This is the standard approach across most of the northern United States, the UK, and similar climates, and it works indefinitely because bay tolerates pot life and pruning so well. Gardeners in marginal zone 8 climates often hedge their bets by growing bay against a south- or west-facing wall and throwing horticultural fleece over it during cold snaps.
Full sun, sharp drainage, and shelter from wind give bay everything it needs
Bay wants a bright, warm, sheltered spot. Give it full sun to light partial shade, aiming for at least five to six hours of direct sun a day. In the ground, the south or west side of a house or wall is ideal because it adds warmth and breaks cold winter wind. Indoors or under glass, the brightest south- or southwest-facing window you have is the right home.
Drainage is the non-negotiable requirement. Bay laurel handles cramped roots and the occasional missed watering, but it will not survive sitting in soggy soil, where the roots rot quickly. It prefers fertile, humus-rich, well-drained ground with a slightly acidic to neutral pH around 6.2 to 6.6. If your native soil is heavy clay, improve the planting area by digging in plenty of compost along with grit or coarse sand to open it up. In a raised bed, the same amendments apply, and bay should sit near the center with room to spread, away from competing herb roots.
Shelter is the third ingredient. Because cold, drying wind damages the foliage more than cold alone, a protected corner or a position among other plantings helps bay come through winter looking its best.
Plant bay laurel in spring or early fall from an established nursery plant
Bay is best started as a purchased plant rather than grown from seed, because seed germinates slowly and erratically and you would wait years for a usable shrub. Nurseries sell young bays in one-, three-, and five-gallon pots, and buying the largest plant you can afford is worthwhile since the plant grows so slowly. Look for healthy, dark green, glossy leaves with no pests, sticky residue, or dieback. Clipped standard “lollipop” or cone-shaped topiary plants cost more but give an instant formal effect.
Plant in spring or early fall, when the soil is warm and the plant has a long stretch of mild weather to settle in before any extreme. To plant in the ground:
- Dig a hole as deep as the root ball and about twice as wide, loosening the surrounding soil.
- Mix compost and grit into the backfill if your soil is heavy.
- Set the plant at the same depth it grew in its pot, never deeper, and check that a standard topiary stands straight before firming the soil around the root ball.
- Water in thoroughly and keep watering regularly for the first two to four weeks while the roots establish.
If you are planting bay as a freestanding tree and intend to let it grow large, allow at least 5 feet of clear space around it, and remember a mature unclipped tree can spread 15 to 20 feet wide. For a clipped shrub, hedge, or topiary, you can plant much closer and control the size with annual pruning.
Container growing keeps bay portable, compact, and easy to overwinter
Growing bay in a pot is the most popular method, and for good reason. A container lets you move the plant into the sun, out of harsh weather, and indoors for winter, and bay’s slow growth and tolerance of root restriction make it an ideal long-term pot subject. Many gardeners keep the same plant in a similar-sized pot for the better part of a decade.
Match the pot to the size of plant you want. A 24-inch (roughly seven-gallon) container will support a mature tree of about five to six feet, while a six-inch pot keeps a plant pruned to under a foot for a windowsill or bonsai. A pot around 14 inches across is a practical middle ground: large enough to grow a two- to three-foot shrub that yields plenty of leaves, small enough to lift and carry. Whatever you choose, the container must have drainage holes, ideally one for roughly every 12 square inches of surface area, and the plant and pot together should be heavy and stable enough not to topple in wind. For a tall plant, a heavy cement or terra-cotta pot lowers the center of gravity; for cold regions, set the pot on a wheeled dolly or caster base so you can roll it indoors.
Use a free-draining mix rather than plain garden soil. A soil-based compost such as John Innes No. 2 with extra grit works well, as does a mix of about four parts all-purpose potting soil to one part cactus or succulent mix, which drains fast while holding enough moisture. Add crocks or coarse material at the base and stand the pot on feet so water escapes freely. Work a little bone meal or all-purpose granular fertilizer into the mix at planting.
When a young bay looks lost in a large pot, you can plant a compatible herb such as sage or rosemary alongside it for a year or two. The companion uses up excess moisture, reducing the risk of root rot around the small bay, and is removed once the laurel fills out.
Water sparingly, feed lightly, and let bay tell you when something is wrong
Bay is one of the least thirsty herbs, and underwatering is far safer than overwatering. In the ground, established plants usually get all the moisture they need from rainfall except during prolonged drought. In a container, water the base of the plant, not the foliage, when the top one to two inches of mix feel dry, then let any excess drain completely away. Err toward letting the surface dry out between waterings rather than keeping the mix constantly damp. Reduce watering sharply in winter, when the plant is barely growing.
The leaves are a reliable gauge. Vibrant, upright, deep-green foliage means your watering is about right. Leaves that turn brown, go crisp, or drop usually signal too little water, while leaves that yellow often mean the roots are too wet. If yellowing spreads, check that the pot is draining and has not become waterlogged.
Bay is a slow grower and does not need heavy feeding. Plants in good ground or rich raised-bed soil may need little or nothing. Container plants benefit from a liquid feed every couple of weeks through spring and summer, ideally one higher in nitrogen to encourage leafy growth, then no feeding at all over winter. A fish-and-seaweed liquid works well outdoors; a slow-release nitrogen pellet or a bonsai feed is better for indoor plants that you want to keep compact, since it avoids the smell. Do not overfeed, as forcing fast growth on a naturally slow plant tends to do more harm than good. Repotting into fresh mix every two or three years, or simply scraping off the top layer and replacing it when the plant is too large to lift, renews nutrients without fertilizer.
Prune in summer to shape, and rejuvenate old plants gradually in late spring
Bay’s resilience to clipping is exactly why it has been a classic topiary plant for centuries, used as lollipop standards, cones, spirals, and pyramids on either side of a doorway. It responds well to regular trimming and holds a clean formal shape, which is why it is now a popular replacement for box where box blight and box tree caterpillar have taken hold.
Do routine shaping in summer. Pinch or cut the growing tips to keep the plant bushy, and trim topiary several times through the growing season to keep the lines crisp. Use sharp secateurs or hand pruners and cut individual stems rather than running hedge shears across the surface, because shears slice through the large leaves and leave an unsightly fringe of cut, browning foliage. Never remove more than about a quarter of the foliage at one time, and tidy plants at the end of summer to set them up for winter.
Mature, overgrown, or leggy bays take hard pruning well, but they are slow to recover, so stage a heavy renovation over two to three years. Cut back roughly half the stems hard in late spring of the first year, let the plant respond with fresh growth, then cut the rest the following year. Late spring is the safest time for hard cuts because the plant has the whole growing season ahead to push new shoots. Always clean your blades with a dilute bleach solution between plants to avoid spreading disease, and save every healthy clipping, because those pruned leaves are exactly what you dry for the kitchen.
Overwinter container bays indoors with a slow acclimation and a cool, bright dormancy
In zone 7 and colder, the make-or-break season is winter, and the routine is straightforward once you know it. Bring the pot indoors before the first hard frost, when nights approach freezing. Rushing a plant from a cool patio into a hot, dry room shocks it, so acclimate it gradually over two to three weeks: set it in a shadier, more sheltered spot first, or shade it with cloth for a few hours a day, lengthening the time each day before the move inside. Before it comes in, prune off any dead or discolored leaves and check carefully for hitchhiking pests so you do not import an infestation.
Indoors, you have two workable approaches. The simplest is a cool, bright dormancy: place the plant somewhere cool with only a few hours of indirect light, where it will essentially rest. While dormant, do not feed it, and water only about once every two weeks, letting the mix dry out completely in between. Alternatively, keep the plant in a warm room with strong direct sun and treat it almost as you would outdoors, watering when the surface dries, though it will still grow little until spring. Either way, keep bay away from cold drafts and from the parched air directly above radiators. Do not be alarmed if a few leaves drop while the plant adjusts to lower light and indoor conditions, this is normal.
In spring, after the danger of frost has passed, harden the plant back off in reverse, inspect it for winter damage, prune away anything dead or unhealthy, resume regular feeding, and return it to its summer position outdoors.
Propagate bay from semi-ripe cuttings or layering rather than slow, unreliable seed
Once you have one bay you like, you can make more, though patience is essential because every method is slow. Three approaches are practical for home gardeners.
- Semi-ripe cuttings are the most reliable route. Take them in late summer from the current year’s growth that has begun to firm at the base but is still flexible at the tip. Strip the lower leaves, insert the cuttings into a gritty, free-draining mix, and keep them in a moist but not soggy environment out of direct sun. Bay roots slowly, often taking six to nine months, so do not disturb the cuttings while they work.
- Layering in spring is even slower but very hands-off. Bend a low, flexible branch down to the soil, nick the underside, pin it in contact with the ground, and leave it to root over a long period before severing it from the parent.
- Seed is possible but frustrating. Germination is poor and erratic, sometimes taking as little as 28 days at a warm soil temperature around 75 degrees Fahrenheit, but often dragging out to a year, and you then face years more growth before the plant is usable. For most people, buying an established plant or taking a cutting is far more sensible.
Bay is largely trouble-free, but watch for suckers, scale, aphids, and spider mites
Bay laurel is a tough, low-maintenance plant with few serious problems, and most of what does go wrong traces back to overwatering or cold. Still, a handful of pests turn up often enough to recognize.
The bay sucker (Trioza alacris) is the most common outdoor culprit. This sap-feeding insect attacks young foliage, causing leaf edges to curl, thicken, and yellow, and the grey-white nymphs hide on the undersides of leaves under a woolly white wax, secreting sticky honeydew. Promptly picking off and destroying affected leaves usually keeps minor outbreaks in check, and natural predators such as ladybirds, hoverflies, and wasps often deal with the rest, so heavy spraying is rarely needed. Scale insects also appear on bay; treat them with horticultural oil or wipe them off individually with a cotton swab dipped in rubbing alcohol.
Indoor and greenhouse plants are more prone to aphids and spider mites. Aphids are tiny sap-suckers that cluster on the undersides of leaves and leave honeydew; dislodge them by spraying the plant with water in a sink or shower, and follow up with neem oil if needed. Spider mites announce themselves with fine webbing and cause stippled, browning, shriveling leaves; they thrive in dry air, so misting and steady watering discourage them, neem oil treats them, and you should prune away heavily webbed foliage. With any pest, clean tools between plants and isolate a badly affected plant until it recovers.
If a bay looks scorched and bare after a hard winter, do not give up too soon. Nick a branch or the trunk with a knife: green tissue underneath means the plant is alive and may push fresh buds in spring. Repot a struggling container plant into fresh, free-draining mix, soak the roots, tease out any that have circled, and give it time.
Harvest mature leaves any time, then dry them slowly to concentrate the flavor
You can harvest bay leaves at any time of year, which is one of the great advantages of an evergreen herb. For the best flavor, pick the larger, older, fully dark green leaves rather than small, soft new growth, because the mature leaves carry the most aromatic oil. Many cooks find the fragrance is strongest as the plant comes into bloom and through summer. Cut leaves cleanly with sharp snips or scissors, and on a young plant take only a leaf or two at a time so you do not stress it. An established plant can spare far more, and in warm climates you can eventually cut whole small branches to dry at once.
Fresh bay leaves are usable straight away and are actually more pungent than dried, but drying is how you build a year-round supply and is the form most recipes assume. Curing for a couple of weeks also mellows the slight bitterness of a fresh leaf into the rounded, savory note prized in soups, stews, sauces, braises, and a classic bouquet garni. Pick leaves in the morning once the dew has dried so they are not damp going in. Then choose a method:
- Air drying gives the best flavor. Either lay the leaves in a single layer on a paper-towel-lined tray or strip the lower leaves from cut stems, tie the stems in small bundles, and hang them upside down. Keep them in a warm, dry, well-ventilated room out of bright light, which can bleach the green and drive off aroma. They will be crisp and brittle in about two to three weeks.
- Microwave drying suits a few leaves in a hurry. Spread clean leaves in a single layer on a microwave-safe plate and run short 30-second bursts, turning the leaves between each, for roughly four to six rounds until brittle.
Once fully dry, strip the leaves from any stems and seal them in an airtight jar, kept away from light and heat. Stored this way, dried bay leaves hold good flavor for up to a year or two before the aroma fades, at which point they are still safe but worth replacing. Press the jar to your nose now and then: when a crushed leaf no longer smells warmly fragrant, it is time to dry a fresh batch from your plant, which, kept in a sunny spot and watered with a light hand, will keep supplying you for many years.
