Citrus can be grown nearly statewide, but most types require protection when cold weather rolls in.
A good way to protect your tree is by trapping ground heat. Cover the entire tree with a fabric cover, and consider using an electric light bulb for additional heat. If your tree is too large to cover completely, wrap the trunk with several layers of cloth. Either way, be sure the covering reaches all the way to the ground and is secured, and remove it when temperatures rise above freezing.
Newly pruned trees are more susceptible to cold damage, so postpone pruning until spring. In North Florida, choose cold-hardy citrus varieties or keep the plants in containers that can be moved to a protected area. With care, your tree can make it through cold weather.
