Palm Trees
 

Being new to palm trees. Can anyone give me advice about why the palm trees look yellow? I have fertilized them but they don't seem to green up. Is this normal for this time of year??

Did you use a specific palm tree fertilizer?

The roots go some distance from the tree, so don't just fertilize near the trunk

Assume you are watering them regularly?

You could try contacting the master gardener and ask your questions. We have 4 palms, 2 Sylvester's and 2 canary. All have been fertilized and regularly watered. The 2 Sylvester's are green, especially when compared to the neighbors, the 2 canary's have very slight yellowing. I get specific palm fertilizer from One Site in Leesburg, 50 pound bag, $50, but I understand there is a firm that delivers for the same price.

The bottom branches turn yellow and then start dying off. These are the branches that get cut off. My landscaper said to look inside the tree, it should be green. The top of the tree with the new growth should also be green. According to my landscaper, Palm trees should be fertilized twice a year. Once in the spring after the potential for frost is gone, sometime after March 15 and 6 months later. If your a snowbird whenever you get back after September 15. If your concerned about you tree take some pictures to the big nursery on 301, just nothing of 466. They are very helpful and sell a good quality palm fertilizer.

Yes They have bubblers on regularly

Epsom salt used only as a supplement to Palm fertilizer ( boron essential )

Palm trees can vary from yard to yard. There's not one patent answer as to what causes yellowing, or why yours might not look like your neighbors. Factor in the age of the tree, when it was planted, etc. Use a good quality fertilizer (Lesco 8-2-12) 1/2 to 1 pound of fert per 1" of tree diameter. Don't skimp on the fertilizer. SiteOne in Leesburg has the fertilizer you'll need. $50 a bag.

They need magnesium. Google yellowing palm trees. I use epsom salt and water it in around the tree.

Lesco 8-2-12 has magnesium.

Palm trees also need manganese. A deficiency can also cause yellowing leaves.

Palm trees should actually be fertilized 3 times a year starting in March. Then June, and then September. Use Lesco 8-2-12 +4 or Palm Gain 8-2-12 +4. The first number is nitrogen, then phosphorus, then potassium. The + 4 is trace elements such as boron, magnesium etc. Lesco can be purchased from John Deere or Fertilizer Direct and Palm Gain can be purchased from Home Depot. This information is research based from University of Florida and UF Extension.

As can potassium and magnesium deficiency.

The use of epsom salts is not recommended by University of Florida research. It can cause too much magnesium in the soil. Best to use a complete fertilizer such as Lesco 8-2-12 +4 or Palm Gain 8-2-12- +4.
