Florida's reputation is sunshine, but anyone who has gardened here for a few years knows the other side: the January cold front that drops temperatures below freezing overnight and leaves tropical trees with brown, crispy leaves by morning. Freezes are rare in Key West, occasional in Miami, regular in Orlando and a yearly event in Jacksonville. The trick is matching your trees to your winters, then knowing how to protect the tender ones.
How cold-hardy is your tree?
Every fruit tree has its own cold tolerance, and young trees are always more vulnerable than established ones. Here's a general way to think about common Florida fruit trees, from toughest to most tender.
Cold-hardy: good choices statewide
- Mulberry: fast-growing, productive and hardy far beyond Florida. Our Everbearing Mulberry is one of the easiest fruit trees for any part of the state.
- Fig: deciduous and cold-hardy. In a severe freeze, a young fig may die back, but it often regrows from the base. The Brown Turkey Fig is a dependable choice.
- Pomegranate: drops its leaves and rests through winter, then blooms in spring. The Azadi Pomegranate is a good one to try.
- Persimmon, blueberry, low-chill peach, pear and muscadine grape: well suited to Central and North Florida with the right varieties for your chill hours.
Moderately hardy: take some cold, appreciate protection
- Loquat: the tree is fairly hardy, but flowers and young fruit can be lost in a hard freeze.
- Satsuma and kumquat: among the most cold-tolerant citrus. Buy certified trees from a registered Florida nursery.
- Starfruit: established trees can often handle a brief light freeze with some damage. Young trees need covering. See our starfruit care guide.
- Mexican-type avocado hybrids: the most cold-tolerant avocados, better for Central and North Florida than West Indian types.
Tender: protect every freeze, or grow in containers
- Mango: young trees can be killed by a freeze, and even mature trees lose leaves, twigs and flowers. Read growing mango trees outside South Florida.
- Guava: grows fast but can be killed back by a hard freeze.
- West Indian avocados: like Catalina, these are best in South Florida.
- Papaya, soursop, jackfruit, tamarind seedlings and cacao: very cold-sensitive. Cacao in particular dislikes even chilly nights well above freezing.
How to protect fruit trees from a freeze
When a freeze is in the forecast, a little preparation goes a long way. These steps follow standard UF/IFAS guidance for home landscapes.
1. Water a day or two before
Moist soil holds and releases more heat than dry soil. Water your trees thoroughly a day or two before the cold arrives. Don't water during the freeze itself.
2. Cover all the way to the ground
The ground releases warmth overnight. A cover that drapes all the way down to the soil traps that heat around the tree. A cover that only wraps the canopy, like an umbrella, does little. Use frost cloth or an old sheet or blanket, and weigh down the edges. Avoid plastic touching the leaves, because it conducts cold and can damage them.
3. Add gentle heat for very tender trees
For small, tender trees, a string of old-style incandescent holiday lights under the cover adds a bit of warmth. Use outdoor-rated lights and cords and keep everything away from water. Modern LED lights give off very little heat, so they won't help much.
4. Protect the trunk of young trees
The trunk and graft union are the most important parts of a young tree. If the top freezes but the graft survives, the tree can regrow true to type. Wrapping the lower trunk with insulating material or banking clean soil around the base for the duration of the cold snap can help. Remove soil banks afterward.
5. Move containers inside
Container trees are the easiest to protect. Roll them into a garage, porch or shed for the night, or cluster them against a south-facing wall and cover them together.
6. Uncover in the morning
Once temperatures climb above freezing, remove covers so the tree doesn't overheat in the sun.
After the freeze: be patient
The day after a freeze, leaves may look wilted, dark or bronze. Resist the urge to prune right away. Damaged leaves and twigs still protect the tree from the next cold night, and it can take weeks to know which branches are truly dead. Wait until spring, when new growth shows you where live wood begins, then prune back to healthy tissue. A quick scratch test also helps: lightly scrape the bark with a thumbnail. Green underneath means alive. Brown and dry means dead.
Hold off on fertilizer until the tree is clearly pushing new growth in spring. Feeding a damaged tree in winter can trigger tender growth that the next cold front will hit.
Plan your planting around the cold
- Plant tender trees in spring so they have a full warm season to establish before winter.
- Stop fertilizing by late summer so new growth hardens before the first front. Our guide on fertilizing fruit trees in Florida explains why.
- Use microclimates. Plant tender trees on the south side of the house, near paving or water, and away from low spots.
