Can a lemon tree survive a freeze?
Among the citrus types most easily killed or damaged by freezing weather are citrons, lemons and limes. Temperatures in the high 20s will kill or severely damage these plants. Properly hardened bearing trees will withstand temperatures as low as 20 degrees Fahrenheit without appreciable wood damage.
Do lemon trees need frost protection?
Mature citrus trees can survive light frost without a cover, but you should wrap the trunks with insulation to protect against hard frosts.
Can Meyer lemon trees survive a freeze?
Meyer lemons, satsumas, and some kumquats have the highest tolerance for cold among the commonly grown citrus, reportedly surviving down to 20 degrees. They tend to drop leaves and have a thinner leaf canopy than other citrus.
How do you revive a lemon tree after freezing it?
Pull a few fruits, cut them open and see if freeze damage is apparent. If it appears that the fruit has frozen, remove it all from the tree. If you do this immediately after a freeze, the fruit can often be juiced and the juice can be frozen for later use.
How do I protect my citrus trees from freezing?
If a hard freeze is on the way, several things can help to protect young citrus trees from cold damage. Wrap the trunk in cloth or bubble wrap. Use tarps, old blankets or plastic sheeting to wrap the tree. Decorating the tree with the non-LED Christmas lights also helps by generating a bit of heat in the foliage.
How cold is too cold for a potted lemon tree?
Lemon and Meyer Lemon Temperature Lemon trees can be defoliated at around 24 degrees. The young fruits of the plants are killed at 29 degrees, and mature fruit will also die at -4 degrees. In colder areas, growing lemon trees in pots can work, as you can then bring them inside when the weather gets colder.
How do you keep a lemon tree after freezing?

What is too cold for citrus trees?
They go dormant in winter, when temperatures drop to 35 to 55 degrees. Freezing weather, however, damages the fruit at 26 to 30 degrees. Young trees are also damaged and may die during frosts, while mature trees are known to have survived for 10 hours in temperatures below 25 degrees.
Are citrus trees frost tolerant?
The main limiting factor for growing citrus is the lack of significant cold tolerance. The ideal temperature range for citrus is between 60- and 90-degrees F, though depending on the species and cultivar, some have better cold tolerance than others.
How do I protect my lemon tree from frost?
You can protect your tree and the fruit left on it from freezing by covering it with a blanket or heavy tarp on those nights where it is predicted to dip below freezing. To do this, build tripods of light lumber or PVC pipe around the trees and cover them with frost cloth or tarps on the coldest nights.
