Growing bell peppers in USDA Zone 13 is a warm-climate pleasure: peppers love heat, and with average winter lows above 60°F and no frost at all, Zone 13 lets you grow them year-round. A pepper plant in Zone 13 can live and produce for a year or more, rather than the single season a temperate garden allows — but the same heat that keeps the plant alive can pause fruit set in the hottest weeks, so the best crops come from plants set out in the cooler months.
This guide covers when to plant bell peppers in Zone 13, how to start them, and how to keep them fruiting through the heat. Bell peppers take 60–90 days to maturity, so a planting this month is fruiting within three months. Use the Zone 13 planting calendar to see what else to sow alongside them.
Zone 13 at a glance
USDA Zone 13 has average winter lows of above 60°F and is frost-free year-round — there is no last or first frost date to plan around. Plan by heat and by the wet and dry seasons instead: heat lovers grow year-round, while cool-season crops only succeed in the coolest months. These are zone averages, not promises for any one garden, so check your local extension service for your area.

When to plant bell peppers in Zone 13
In Zone 13, bell peppers can be planted at any time of year because there is no frost — average winter lows are above 60°F and the zone is frost-free, so there is no last or first frost date to plan around. The best fruit set comes from plants set out in the cooler months, roughly November to February, when nights are mildest. A hot-season planting is still possible, but choose heat-tolerant varieties, give afternoon shade, and expect setting to pause in the hottest weeks. Bell peppers take 60–90 days to maturity, so work back from when you want fruit. Check your local extension service for the best planting windows in your area.
Starting bell peppers in Zone 13
Bell peppers are started indoors, then transplanted as sturdy seedlings. Sow in trays or small pots, keep them warm — peppers germinate best in warmth — and give them strong light; seeds germinate in 7–14 days. Grow them on until they have several true leaves, harden off for a week, and transplant them out in the cooler months. Handle seedlings by their leaves, never by their delicate stems, and set a stake in place at planting time for taller varieties, since a laden pepper plant can topple in a tropical storm.
Soil, spacing, sun and water
Bell peppers want full sun and rich, well-drained soil with a pH of 6.0–6.8. Dig in well-rotted compost before planting and space plants 18–24 inches apart, since crowded plants stay small and invite disease. Mulch thickly to keep soil moisture even, which helps prevent blossom-end rot — the same problem that affects tomatoes. Bell peppers need moderate water: water deeply and less often rather than lightly every day, water at the base in the morning so leaves dry before night, and check the soil a finger's depth down before watering again. The watering calculator will help you work out a watering routine for your beds.
Companion planting
Good companions for bell peppers include basil, onions, tomatoes, marigolds, carrots. Basil is the classic pepper companion, while marigolds draw pollinators and beneficial insects to the bed. The companion planting finder can suggest combinations for your whole bed. Do not plant peppers where other members of the nightshade family grew last year, and keep them away from fennel, which competes with them.
Pests and problems
The common pests and problems to watch for with bell peppers are aphids, cutworms, flea beetles, whiteflies. Aphids cluster on shoot tips and buds and can be knocked off with water; flea beetles make small holes in young leaves, and whiteflies gather under leaves in hot weather. Cutworms can sever young stems at soil level, so protect new transplants with a collar around the base. In Zone 13's humidity, bacterial spot and other leaf diseases follow wet foliage — water at the base, space plants for air flow, and remove affected leaves promptly.
Harvest and storage
Bell peppers ripen 60–90 days after transplanting. Pick green peppers when they are full-sized and firm, or leave them on the plant to ripen to red, yellow or orange for a sweeter flavour — the longer they stay, the sweeter they get, but the fewer new fruit the plant will set. Pick regularly, using a clean cut rather than pulling, since the stems are brittle and a pulled fruit can break the branch. Store peppers in the fridge for up to two weeks, or freeze them chopped for cooking. In the heat of the hottest months, fruit set can pause, then resume as temperatures ease, so keep plants watered and fed through the pause.
Making the most of Zone 13
Zone 13's advantage is time: with no frost, a pepper plant can produce for a year or more. The trick is to plant for the cooler months for the heaviest crops, use heat-tolerant varieties in the hot season, and keep picking regularly so the plant keeps setting.

Frequently asked questions
When should I plant bell peppers in Zone 13?
In Zone 13, bell peppers can be planted at any time of year because there is no frost — average winter lows are above 60°F and the zone is frost-free, so there is no last or first frost date to plan around. Check your local extension service — these are zone averages, not exact dates for your garden.
How long do bell peppers take to grow in Zone 13?
Seeds germinate in 7–14 days, and the crop takes 60–90 days to maturity. In Zone 13, allow the longer end of the range if conditions are hot at sowing time, since extreme heat can pause fruit set.
Can I grow bell peppers all year in Zone 13?
Yes, Zone 13 is frost-free, so bell peppers can be planted year-round, but fruit sets best in the cooler months from roughly November to February, and setting can pause in extreme heat, so plan your main crop for the cooler season.
What soil and spacing do bell peppers need in Zone 13?
Bell peppers need full sun and soil pH 6.0–6.8, spaced 18–24 inches apart. Dig in well-rotted compost, water deeply, mulch, and test your soil through your local extension service.
