I have seen several freeze damaged palm trees in the central Texas area this year after the relatively cold winter. Now that spring is here, it is a great time to start getting them back into shape. Now that the damage has been done, the first thing you need to do is prune all of the dead fronds from the tree. Sometimes, this means removing all fronds from the tree. A fairly accurate test to assess the extent of the damage is too gently tug on a leaf newly emerging from the trunk. If the spear pulls out, there is damage to the tissue of the palm, and can result in the loss of your palm tree. Palm trees will typically grow out of the cold damage but they could take up to 6 months to completely recover.
Palm trees obviously do not like frost or freezing temperatures, and are made to be in a more tropical climate. We can't control the weather here, but we can control how we prepare for the cold weather in advance. Your palm trees should be fertilized 3 to 4 times per year. When shopping for a palm tree food or fertilizer, I recommend using one that is high in manganese, nitrogen, magnesium, potassium, and iron. When you give your palm trees the nutrients that they need, they will be healthier and more likely to be able to make it through the next winter. Palm trees should be pruned twice per year, but you should avoid pruning them in the winter. We typically use the 3 to 9 method when pruning palms. Overpruning palms can do more damage than good. Hopefully this information has been useful to you, and maybe it can help save many palms in the central Texas area for years to come.
