Bay is the quiet workhorse of the herb garden: a few dried leaves transform soups, stews, rice and braises, and the plant itself is a handsome evergreen shrub or small tree. In Zone 12 it grows happily outdoors year-round, but be warned — bay is a slow grower. This is a plant you buy once, plant well, and harvest from for decades, not a quick seasonal crop.
Like every crop in the tropics, bay leaves rewards gardeners who work with Zone 12's seasons — the cooler, drier months and the hot, wet months — rather than against them. The planting calendar hub gives the Zone 12 picture month by month, and our guide to when to plant bay leaves in Zone 11 shows how the timing shifts in a cooler zone.
Zone 12 at a glance
USDA Zone 12 covers the warmest, most tropical parts of the United States — Hawaii, Puerto Rico, Guam and the U.S. Virgin Islands. Winters are warm, with average winter lows of 50 to 60°F, and the growing season never really ends.
Zone 12 is frost-free year-round: there is no average last spring frost and no average first autumn frost. That means you plant by heat and by the wet and dry seasons, not by frost dates. These are USDA zone averages, not exact figures for any one garden — always check your local extension service and the forecast before planting.

When to plant bay leaves in Zone 12
Plant bay in Zone 12 in spring or early autumn, at the start of a rainy spell, so young plants establish with the help of natural rain. Because Zone 12 is frost-free, with winter lows of 50 to 60°F, there is no frost date to wait for — any month with warm soil and reliable moisture will do. Seed germinates slowly, in 14–28 days, and a bay grown from seed takes 1 to 2 years to reach a useful size, which is why most gardeners buy a young plant. Check your local extension service for the best local planting window. See the Zone 12 March planting guide for what else to plant that month.
Starting bay leaves in Zone 12
Start bay indoors from seed, or far more sensibly buy a small plant from a nursery. Seed is slow and erratic, germinating in 14–28 days, and seedlings grow slowly for their first year. A nursery plant a foot tall is already a year or two old and will establish much faster. Plant it out in spring, spacing plants 36–48 inches apart — or much further if you plan to let it grow into a tree. Bay also grows well in a large pot, which keeps its size manageable and lets you move it.
Soil, spacing, sun and water
Bay needs full sun and well-drained soil with a pH of 6.0–7.0. It tolerates poor soil and even some shade, but it will not tolerate waterlogged roots, so in Zone 12 plant it on a slight mound or in a raised bed where the rainy season drains away. Water needs are low once established — water young plants regularly for the first year, then only in dry spells. A mulch of compost keeps the roots cool and the soil moist.
Companion planting
Good companions for bay include tomatoes, peppers, marigolds and cabbage. As a slow-growing shrub it makes a useful windbreak or backdrop at the sunny edge of a vegetable garden, and its aromatic leaves are said to deter some pests. Give it room: a mature bay will shade out anything planted too close. The companion planting finder can suggest combinations for your whole bed.
Pests and problems
The common pests to watch for with bay are aphids, slugs and cutworms. Aphids may cluster on soft spring growth — wash them off with water. Slugs nibble young plants in wet weather, so keep mulch away from the stem. Cutworms can damage young transplants at soil level. Bay is otherwise remarkably trouble-free in Zone 12; its tough, aromatic leaves are unappealing to most pests, and scale insects are the main thing to watch for on older plants.
Harvest and storage
Harvest bay 1 to 2 years after planting, once the plant is well established — and then harvest lightly, taking only a few leaves at a time. Pick mature, dark green leaves, which have the strongest flavour, and dry them for two weeks in a warm, airy place before using; dried bay is actually more flavourful than fresh. Store dried leaves in a sealed jar away from light. A single mature plant produces more bay than most households can use, so one plant is enough. Use the herb drying calculator to work out drying times for your harvest.
Growing bay in a pot in Zone 12
A pot is the best way to grow bay in Zone 12 if space is limited or you want to keep the plant small. Choose a large, heavy pot with drainage holes, fill it with a gritty, free-draining mix, and plant your bay in spring. Water it well for the first year, then let it dry out between waterings — bay in a pot rots quickly if it stays wet.
Prune lightly in spring to keep the shape you want: a standard on a single stem, a bush, or a neat cone. Potted bay can live for decades with an occasional top-dressing of compost and a feed in spring, and it is easy to bring under cover in the worst of a storm.

Frequently asked questions
When should I plant bay in Zone 12?
Plant in spring or early autumn, at the start of a rainy spell, so young plants establish well. Zone 12 is frost-free, so any warm month with reliable moisture works.
How long does bay take to grow?
Bay is slow: seed takes 14–28 days to germinate and a plant takes 1 to 2 years to reach a useful harvest size. Buy a nursery plant to save a year or more.
Can I grow bay in a pot?
Yes — bay grows very well in a large pot with free-draining soil, and a pot keeps its size manageable. Water well in the first year, then let it dry between waterings.
Are fresh or dried bay leaves better?
Dried leaves are more flavourful than fresh, so dry picked leaves for two weeks in a warm, airy place before using, and store them in a sealed jar.
