Cherries are the fruit least suited to Zone 13, and this guide will be straight about it: sweet cherries need a long, cold winter to flower and fruit, and Zone 13 winters — with lows above 60°F — never come close. No low-chill sweet cherry variety fruits reliably in a frost-free tropical climate, and a cherry tree planted in Zone 13 will usually grow leaves for years and never set a single fruit. That is the climate, not your care. If you want cherry-like fruit in the tropics, grow a tropical substitute instead: Surinam cherry and Barbados cherry are real tropical fruits that thrive in Zone 13 heat. USDA Zone 13 is the hottest hardiness zone in the United States, covering tropical Puerto Rico and similar frost-free places, with average winter lows above 60°F and no frost at all in an average year. That changes how you plan: there is no last or first frost date to work back from, so you plant by heat and by the wet and dry seasons instead. Frost dates are zone averages and vary by microclimate, elevation and year — check your local extension service.
Zone 13 at a glance
Zone 13 is the hottest hardiness zone in the United States, and cherry growing has to be planned around heat and rain rather than frost. There is no last frost date to count back from and no first frost date to race against, so the wet and dry seasons do the job that frost dates do in colder zones. Work with that rhythm and cherries will do far better than if you plant by a calendar date alone.

When to plant cherries in Zone 13
If you still want to try a cherry tree, plant it at the start of the cooler, drier season, when a young tree can establish roots before the wet season. Zone 13 is frost-free, so there is no frost date to plan around; the cooler months are simply the kindest time to transplant. Buy a grafted tree from a nursery — seed takes 30–90 days to germinate and many years to fruit, and seedlings rarely resemble the parent. Published days to maturity are 1095–2555 days, three to seven years, but in Zone 13 most cherry trees never reach fruiting at all. The planting calendar hub gives the Zone 13 picture month by month, and for a cooler-climate comparison see Cherries in Zone 10.
Starting cherries in Zone 13
Start with a grafted tree in a large container or a prepared planting hole, and plant it at the same depth it grew in its pot. Give it a stake for the first year or two, and prune it to an open shape so air and light reach the centre — airflow matters in a humid climate. Plant two different varieties if you can, since cherries fruit better with cross-pollination. Before you buy, ask your local extension service whether any cherry variety has ever fruited in your area — in most of Zone 13 the honest answer is no. The plant spacing calculator helps you plan the tree's footprint.
Soil, spacing, sun and water
Cherries grow best in full sun, in deep, well-drained soil with a pH of 6.0–6.5. Space trees 144–216 inches apart — a cherry is a large tree, and it needs room for its canopy and its roots. Dig in compost before planting and keep the planting hole well drained, since wet feet in the rainy season cause root rot. Mulch thickly to keep roots cool and moist. Test your soil through your local extension service before you amend it.
Cherries need moderate water, and young trees need it most: water deeply and regularly for the first two years until roots are established, then water in dry spells. Water at the base in the morning and keep water off the leaves, which invites fungal disease in humid air. In the wet season, hold back and make sure the planting drains. The watering calculator can help you judge amounts in the dry months.
Companion planting
Good companions for cherries include borage, marigolds, clover and chives. Clover under the tree fixes nitrogen and keeps the soil covered, and marigolds help with soil pests. Keep grass away from the trunk, since it competes for water and harbours pests. A far more reliable Zone 13 fruit tree is figs, which fruit well in a frost-free garden. The companion planting finder can suggest combinations for your whole bed.
Pests and problems
The common pests to watch for with cherries are aphids, Japanese beetles, birds and spider mites. In Zone 13, fungal disease in humid weather is often a bigger problem than insects: prune for airflow, keep leaves dry, and remove diseased leaves promptly. Aphids cluster on new shoots and can be washed off with water. Birds take any fruit that does set, so net the tree if it fruits. The most common Zone 13 problem, though, is not a pest at all but lack of chill — a healthy-looking cherry that never flowers is telling you the climate does not suit it.
Harvest and storage
Be honest with yourself about expectations: in Zone 13, a sweet cherry tree will very likely never fruit. If it does set a few fruit, pick them when they are fully coloured, firm and sweet — about 1095–2555 days after planting from seed, sooner from a grafted nursery tree. Pick in the morning and handle fruit gently. If your tree has not flowered after several years, replace it with a tropical fruit tree that suits the climate — a Surinam cherry or Barbados cherry gives you cherry-like fruit in Zone 13 heat, and a fig or citrus will fruit reliably.
Frequently asked questions
When should I plant cherries in Zone 13?
Plant at the start of the cooler, drier season so the young tree can establish before the wet season. Zone 13 is frost-free, so there is no frost date to wait for.
Can cherries grow in Zone 13?
Honestly, no — sweet cherries need a long, cold winter that Zone 13 never provides, and they very rarely fruit here. Tropical substitutes such as Surinam cherry and Barbados cherry thrive in Zone 13 instead.
How long do cherries take to fruit in Zone 13?
From seed, 1095–2555 days (three to seven years) to maturity in a suitable climate. In Zone 13, most cherry trees never fruit at all.
What soil and spacing do cherries need in Zone 13?
Cherries need full sun and deep, well-drained soil at pH 6.0–6.5, spaced 144–216 inches apart. Test your soil through your local extension service.
