Bay

Laurus nobilis

A Mediterranean evergreen tree that will reach eight metres if left alone, which is the fact a herb bed cannot accommodate. Grown in a pot and clipped it is a decades-long plant needing almost nothing, and one bush supplies more leaves than any household uses.

What kind of herb this is

Herbs are a kitchen grouping rather than a botanical one, and the plants in it want opposite things. This is the one distinction that decides how to treat it.

Wants sun, poor free-draining ground and very little water once established. Far more of these die from winter wet at the roots than from cold air, so drainage matters more than hardiness ratings suggest.

Treated the same way: borage, chamomile, hyssop, lemon thyme, marjoram, oregano and 7 more in the same group. The herb bed, split by regime

Why winter wet kills a Mediterranean herbTwo soil cross-sections side by side. On the left, a well-drained planting: the crown of a rosemary sits slightly proud of the surrounding soil on a low mound, the root zone is open gritty soil with air between the particles, and arrows show winter rain moving down and away past the roots. The plant above is dense and well furnished. On the right, the same herb in heavy soil in a hollow: the crown sits level with or below the surface, the root zone is dense soil over a compacted pan, and winter rain has nowhere to go so a water table stands in the root zone from November to March. The roots there are drawn broken and dashed to show they have died, and the plant above is sparse and thin. The point is that the plant looks unharmed all winter because an evergreen with a full canopy asks almost nothing of its roots in January, so the loss only shows the following spring when it fails to grow.Sharp drainagecrown proud, water moves throughroots stay firm and paleair between the particles all winterWinter wetcrown in a hollow, water standswater table, Nov–Marcompacted pan — nowhere to goroots dark, soft and sourand the plant above still looks fineopen gritty soilheavy soilstanding waterliving rootsPlanting on a low mound, adding grit, or standing a pot on feet all do the same job: get the crown above the water.
The damage happens in January and shows in May. An evergreen herb asks almost nothing of its roots in winter, so a drowned root system stays invisible until the plant is asked to grow and cannot.

Almost any herb will sit on a windowsill in July. This is about whether it is still there in March, which is the part a pot on a supermarket shelf does not tell you.

What happens when it flowers

On a herb this is rarely a problem and rarely nothing. It is the point at which the plant stops being what you grew it for — by a lot, a little, or not at all.

The normal way to grow it in Britain: a pot restricts the size, allows it to be moved into shelter in a hard winter, and a clipped bay lives happily in the same container for years.

Where and how you can grow it

Each way of growing is assessed separately, and “not assessed” is a real answer rather than a gap we have filled in with a guess.

Growing it

  • ProtectionMove a potted bay into shelter, or wrap the pot, in a hard winter. The roots in a container freeze far more readily than roots in the ground, and that — rather than the air temperature — is what kills bay trees in Britain.
  • PruningClip in summer to keep the shape. Bay tolerates hard pruning and regrows from old wood, so a neglected plant can be brought back rather than replaced.
  • WateringA bay in the ground needs watering only in its first two summers. A bay in a pot is a different plant entirely and is the commonest bay to die: a thirty-litre container holding a mature evergreen dries out fast in summer wind, and the damage shows weeks later as brown leaf edges and leaf drop. Check by weight or by pushing a finger deep into the compost, soak it thoroughly when it is dry, and keep watering lightly through mild winter spells — a pot can dry out in February wind while nobody is looking.
  • FeedingA bay in open ground needs no feeding. A clipped bay in a pot does, because it is being asked to replace the growth you keep cutting off from a fixed volume of compost: give a balanced liquid feed monthly from April to August, and top-dress with fresh loam-based compost each spring. Yellowing older leaves on a potted bay usually mean exhausted compost rather than disease.
  • HarvestingPick leaves in any month — this is a genuinely year-round herb. Take mature leaves rather than the soft pale new ones at the shoot tips, which have far less flavour, and pick from all round the plant so a clipped shape stays even. Leaves dry well and are one of the few herbs that many cooks prefer dried.
  • PropagationTake semi-ripe cuttings of the current season's growth in late summer, about 10 cm long with a heel, and root them in gritty compost in a covered propagator. Bay is slow and unreliable to root — expect a good proportion to fail and take more than you need — but a rooted cutting makes a plant that will outlive most of the garden.

Where to make a pruning cutFour stems compared. The first is cut cleanly on a slope about five millimetres above an outward-facing bud, sloping away from it, and is labelled correct. The second is cut too far above the bud, leaving a long stub that dies back. The third is cut too close, into the bud itself, which loses the shoot. The fourth is cut sloping towards the bud so rain runs onto it rather than away, which rots it. In every case the bud points outwards, away from the centre of the plant.Correct5 mm, sloping awayToo highstub dies backToo closebud lostSloping inrain sits on the bud
The bud you cut to becomes the new shoot, and it grows in the direction it points — which is why an outward-facing bud opens the plant up and an inward-facing one crosses the middle.
Four ways to make more plantsFour propagation operations compared, each showing where the separation is made and what must be present on both sides of it. Division: a clump cut between crowns, with roots and at least one growing point on every piece. Stem cutting: a shoot cut just below a leaf node, because the node is where roots form, with the lower leaves removed. Runner: a plantlet already rooting where it touches the ground, severed from the parent only after its own roots have taken. Offset: a young shoot at the base of the parent, separated with its own roots attached. In each case the cut is marked and the part that must be retained is labelled.Divisioncut between crownsroots on every piececut below a nodeStem cuttingroots form at the nodestrip the lower leavesRunnerlet it root firstthen sever the linkOffseta shoot at the basetake its roots with it
The rule is the same in all four: the new piece needs both a growing point and roots of its own. A cutting is the exception that has to make its roots afterwards, which is why the node matters so much.

Is it worth putting under cover?

Whether it will grow there is on the methods table above. This is whether the space is well spent, which is a different question and usually the one being asked.

 Not a windowsill crop. The reason is given — usually light, root volume or sheer size. It is a shrub. A bay wants a cool winter rest and steadily drops leaves in warm dry indoor air, where it also picks up scale insect that is very hard to clear.A bay in a pot by a door is a good plant. A bay on an indoor windowsill is a slowly declining one.

Growing it without soil

Nearly anything can be grown in a soilless system by somebody with enough equipment. The useful question is whether it is worth it, in which technique, and what goes wrong.

Not worth it

It can be made to grow, but a soilless system is the wrong tool — usually because of rooting volume, running cost, or a result no better than a pot of compost.

Published targets vary by cultivar, growth stage, water source and technique, and the figures that apply to your system are on the product you bought.

Harvesting

  • When it is readyThere is no season to wait for: bay is evergreen and any mature leaf is ready. Take the darker, leathery leaves from wood that is at least a season old rather than the soft pale growth at the shoot tips, which is thin and has noticeably less flavour. Leaves are at their most aromatic in late summer.
  • How to pick itPull or snip individual leaves from all round the plant so a clipped shape stays even. Dry them flat under a weight if you want the dried leaf, which many cooks prefer.
