When to plant beets zone 13 — in USDA Zone 13, that question has a different answer from almost anywhere else in the United States. Zone 13 is the hottest USDA zone, frost-free year-round with average winter lows above 60°F, so there is no last frost to wait for and no first frost to beat. Instead you plant by heat and by the wet and dry seasons, and beets is a cool-season crop, and in Zone 13 it is a coolest-months-only crop. This guide gives the timing and the honest limits, using published crop ranges — and, as always, check your local extension service for varieties suited to your area.
When to plant beets in Zone 13
Beets are a cool-season root crop, and in Zone 13 they belong in the coolest months, roughly December through February. They cope with warmth better than carrots, and the leaves are edible too, so even a modest crop is useful — but hot soil makes roots woody and slow to swell. Sow at the start of the cool season, choose fast-maturing varieties, and harvest young, because a beet left too long in the heat turns tough rather than tender.
Zone 13 covers only the hottest tropical parts of the United States, so these are zone averages, not a promise for any single garden — microclimate, elevation, rainfall and soil all shift the details.
Zone 13 planting data for beets
Published ranges from standard horticultural references — germination and maturity vary by variety, soil and weather, so treat them as guides, not guarantees. Zone 13 is frost-free, with average winter lows above 60°F, so no frost dates appear here: there are none to give.

Starting beets in Zone 13
Sow beets directly where they will grow — they dislike transplanting — in the coolest months. Germination takes 7–14 days, and each wrinkled seed is actually a cluster that produces several seedlings, so thinning is essential. Sow into moist soil, keep the seed bed damp until germination, and thin seedlings to the spacing in the table below, eating the thinnings as baby greens. A light mulch once seedlings are up keeps the soil cool and moist.
Soil, spacing and sun for beets
Beets want full sun in the cool season and loose, well-drained soil with a pH of 6.0–7.0. Dig in compost before sowing, but avoid fresh manure, which makes roots fork and grow hairy. Space plants 3–4 inches apart, with rows wide enough for air to move, and keep the bed weed-free while plants are young. Raised beds help in heavy tropical soils, where clay stops roots from swelling evenly.
Watering beets in Zone 13
Beets have moderate water needs, with even moisture the key to tender roots: alternating wet and dry spells makes roots woody and cracked. Water deeply and regularly at the base, mulch to slow evaporation, and in the dry season water thoroughly a few times a week. In the wet season, drainage matters more than watering, because waterlogged soil rots roots. If leaves wilt in the afternoon sun, water in the morning rather than the evening.
Companion planting for beets
Good companions for beets include marigolds, basil, onions and lettuce. These pairings come from standard companion-planting references. Keep companions low and open so air can move, and avoid planting beets next to other members of the Amaranthaceae family in the same season, since they share pests and diseases. For a quick check, try the companion planting finder.
Pests and problems in Zone 13
The common pests for beets are aphids, slugs and cutworms. In Zone 13, warm, humid weather means pests and diseases are active all year — there is no winter to knock them back — so check plants every few days and act early. A strong jet of water knocks most aphids off, hand-pick larger pests in the morning, and remove badly infested leaves before a small problem becomes a large one. If damage is severe or you cannot identify the culprit, ask your local extension service — and use the pest identifier helper to narrow it down.
Harvest and storage
Beets take 50–70 days to maturity. Pull roots when they are about the size of a golf ball — young beets are tender and sweet, while oversized ones turn woody in the heat. Loosen the soil with a fork before pulling, twist off the tops rather than cutting them (which makes roots bleed), and eat the leaves too — they cook like chard. Eat fresh or store in a cool, damp place; in tropical warmth they do not keep long, so harvest as you need them.

Frequently asked questions
Can you grow beets in Zone 13?
Yes, in the coolest months, roughly December through February. Zone 13 is frost-free with winter lows above 60°F, so hot soil makes roots woody. Sow early, keep moisture even, and harvest young.
Why are my beets woody?
Uneven watering and heat are the usual causes. Keep the soil evenly moist with mulch and regular watering, and pull roots young — about golf-ball size — rather than leaving them to grow large.
Do I need to thin beets?
Yes — each beet seed is a cluster that produces several seedlings. Thin to 3–4 inches apart, and eat the thinnings as baby greens. Crowded beets stay small and thin.
Can you eat beet leaves?
Yes — cook them like chard. They are one of the best reasons to grow beets in Zone 13, since the leaves crop even when the roots are modest.
