Cold Damage Palm Tree and Shrub Care

By Kurt On February 19, 2009 34 Comments

Did You Receive Cold Damage in Your Florida Landscape?

Now that Florida has experienced freezing temperatures many people are wondering…“Will I need to replace my trees and shrubs?”

Most likely you won’t have to replace all of them. They can bounce back from the cold even if they have been hit hard. “What can I do and how can I tell what to expect?“  are questions many of you have.

How about my Shrubs?

First you will see the leaves turning brown and dropping off. This is a normal and natural process for them to do. Don’t be alarmed if all that is left are branches and stems. The way to check if they are still alive is to scrape off the bark with your fingernail going all the way down to the base of the shrub. If you see green tissue, they are still alive. Also remember the roots can still be alive so don’t remove them right away.

Pruning Cold Damaged Shrubs:

If part of the stems or branches are brown or hollow they will need to cut back to where the green begins. Even if this means cutting them back all the way down to the base of the shrub. The tops can be dead but the bottoms can be still alive. Do Not begin to prune now. Wait until Springtime begins which should be towards the end of March. The shrub is still in shock and plus you you don’t want to stimulate new growth for another freeze can still happen. Just be patient and hold off pruning for now.

Fertilizing Your Shrubs After a Freeze:

Do Not fertilize your shrubs right now, wait until spring arrives. It is best to leave them alone for now. When springtime begins, apply a “Slow-Release” Granular Fertilizer such as “6-6-6″ or “8-10-10″. It is okay to continue to water as you normally would even if a freeze has occurred. By Spring you will know what survived and those that did not.

Palm Tree Cold Damage Treatment:

Palm trees that have been hit by cold damage need to be immediately treated with a Fungicide such as “Liquid Copper“. Spray them two times fourteen days between each treatment. Do Not treat more than twice.

Make sure the trunk gets treated thoroughly so the tree will get a drink, soaking it up. Spray the leaves where they are still green with a Nutritional Palm Liquid Fertilizer. There is no need to treat the brown areas on the leaves. Wait until Springtime to apply a Slow-Release Granular Fertilizer formulated for Palm Trees.

Pruning Cold Damaged Palm Trees:

Prune off all dead branches to where they are all eliminated. Cut back brown tips to where green begins. Leave the green portions of the branches even if they are spotted yellow. If newly grown branches and leaves appear to be deformed, brown, or abnormal, the tree has been severely damaged. Any sudden collapse of some or all branches emerging in the crown will indicate the trunk is damaged. This can result in a loss of the palm tree.

Palm trees should grow out of the cold damage but will take some time to completely recover. It can take four to six months well into the summer to return to normal. Only time will tell just how bad they have been affected by freezing temperatures.

Conclusion:

Don’t give up and throw in the towel because it is not a hopeless case. Good chances are your trees and shrubs will bounce back and be fine. Don’t panic. Just wait patiently to find out how bad it realy is. By springtime you will know if any need to be replaced.

Look forward to spring! To begin a new garden with colorful Annuals to complete your landscape.

Spring is ahead!
