Bay Leaves repay a little planning around what grows beside them. Bay Leaves are a slow-growing evergreen shrub or small tree whose leaves are a kitchen staple, grown for cooking, and a long-lived plant for a large pot or a sheltered corner. They need full sun, soil with a pH of 6.0–7.0, 36–48 inches of space and 365–730 days to reach maturity, so their neighbours need to suit the same bed and the same season. This guide lists the companions for bay leaves from our crop data, how each one is thought to help, and which close relatives to keep apart.
There are 4 companions listed for bay leaves here: Tomatoes, Peppers, Marigolds and Cabbage. Companion planting is traditional garden practice rather than proven science, so benefits below are described in those terms — what gardeners have long said and done. Bay Leaves are in the Lauraceae family, need low water, and are started indoors and transplanted out once the weather warms; they are tender, so frost will kill them and they should only go outside once all danger of frost has passed. Check any pairing first with the companion-planting finder.
Best companion plants for bay leaves
| Companion | Why it is grown with bay leaves |
|---|---|
| Tomatoes | A tall, sun-loving neighbour for the same warm bed; plant the herb at the sunny edge so it is not shaded out, and keep spacing generous for airflow. |
| Peppers | Another heat-lover for the same sunny bed; its upright habit leaves room at its feet for low herbs. |
| Marigolds | Grown as a border or dotted through the bed; its roots are traditionally said to discourage some soil pests, and its flowers attract beneficial insects. |
| Cabbage | Bay's aromatic leaves are traditionally said to help mask neighbouring plants from pests that hunt by smell. |
Tomatoes are the first companion to reach for with bay leaves, and it is a slow, long-term plant, so companions are best thought of as neighbours for its first years while it sizes up. It is the tall neighbour that sets the shape of the bed: stake it well, keep the lower leaves clear, and plant the herb at its sunny base where it gets light without being shaded out.
How companion planting works
Companion planting works through four overlapping mechanisms.
Pest confusion. Many pests find their host plant by scent. Strong-smelling companions such as aromatic herbs are traditionally said to mask that scent, so the pest passes by. It is a delaying effect, not a barrier.
Pollinator and beneficial-insect attraction. Several companions here flower — Marigolds — drawing pollinators and beneficial insects in. Let a few flower.
Nitrogen fixing. Nitrogen fixing does not apply here — none of the listed companions is a legume.
Ground cover and root layers. No companion here is a ground-cover plant, so mulch does that job instead. Deep roots beside shallow ones also compete less for water and nutrients.
None of this replaces the basics. Spacing, watering, rotation and weekly inspection matter more than any pairing.
Plants to avoid near bay leaves
The plants to keep away from bay leaves are its own relatives — but bay leaves have none in our crop data. Bay Leaves belong to the Lauraceae family, and no other crop in our 120-crop data set shares that family, so there is no same-family neighbour to avoid on that basis.
That does not mean anything goes. The rule that still matters is rotation: do not plant bay leaves in the same spot year after year, because the pests that bother them — aphids, slugs, cutworms — build up in the soil and on old plant debris. Move them to a fresh bed each season and clear old stems at the end of the year.
Planting layout and spacing
Give it 36–48 inches — or a large container you can move under cover in winter — and be patient: bay takes 365–730 days to reach maturity.
Give bay leaves their full spacing of 36–48 inches between plants. Crowded bay leaves mean poor airflow, more disease and smaller harvests, and no companion plant compensates for it. Work out how many plants fit your bed with the plant-spacing calculator or the square-foot garden planner.
Plant companions in the spaces the spacing leaves, not instead of it. Low companions go in the gaps and along the bed edges; taller ones go at the north side so they do not shade the bay leaves; scented herbs go closest to the crop, dotted through the row.
Bay Leaves are started indoors and transplanted out once the weather warms: sow under cover where needed, expect germination in 14–28 days, and set plants out once the weather is right. Work backwards from your last frost date with the seed-starting calculator. Bay Leaves need full sun and soil with a pH of 6.0–7.0. Water needs are low, so water sparingly once established and never let the soil stay wet — most failures come from too much water, not too little. The watering calculator gives a starting point for your bed size. Expect 365–730 days from sowing to maturity.
Common problems and fixes
The pests most often reported on bay leaves are aphids, slugs, cutworms. Companions may reduce pressure, but they do not prevent them — inspect leaf undersides and new growth weekly and act while numbers are low.
| Problem | What you see | First fix |
|---|---|---|
| Aphids | Sap-sucking insects on new growth; leaves curl. | Wash off with water; encourage ladybirds. |
| Slugs | Chewed leaves and silvery trails, worst in damp weather. | Beer traps or copper tape; clear debris. |
| Cutworms | Caterpillars that fell seedlings by chewing stems at soil level. | Cardboard collar around each young stem. |
Aphids
Wash them off with a strong jet of water and leave ladybirds and lacewings alone to eat them. Check the undersides of young leaves, where colonies start.
Slugs
Slugs feed at night in damp weather. Clear boards, pots and debris where they hide by day, and set beer traps at soil level near the worst-hit plants.
Cutworms
Push a cardboard collar an inch into the soil around each young stem. Check beds at night with a torch when seedlings start falling.

Frequently asked questions
What is the best companion plant for bay leaves?
The most widely recommended companions are tomatoes. A tall, sun-loving neighbour for the same warm bed; plant the herb at the sunny edge so it is not shaded out, and keep spacing generous for airflow.
What should not be planted near bay leaves?
No other crop in our data shares the Lauraceae family with bay leaves, so there is no same-family neighbour to avoid. The thing to avoid is replanting bay leaves in the same spot year after year, which lets its pests build up in the soil.
Can I plant bay leaves with peppers?
Yes. Peppers are on the companion list for bay leaves. Another heat-lover for the same sunny bed; its upright habit leaves room at its feet for low herbs.
How far apart should bay leaves and their companions be planted?
Space bay leaves plants 36–48 inches apart, and put companions in the gaps, along the edges and at the ends of rows. The plant-spacing calculator works out how many plants fit your bed.
Does companion planting replace pest control?
No. It may reduce pest pressure, but it does not replace inspection, spacing, watering, rotation and good airflow. Check plants weekly and act early.
