| we have approx; 40 acreca baby palms installed in our front yard, about feet tall. what type of fertilizer shoud we be using and how often?
According to the Florida Extension Service palms in home landscapes need a fertilizer with the nutrients nitrogen, phosphorus, potassium and Magnesium in a 2:1:3:1 ratio and contain sulfur You can purchase special palm blends that are close to this, or use a standard turf fertilizer that has a 3:1:2 ratio of nutrients (such as 15-5-10 or similar blend) and supplement it with a fertilizier called potassium magnesium sulfate (may also be called K-Mag or Sul-Po-Mag) which contains about 22% potassium, 11% magnesium, and 21-22% sulfur.
Use 2 cups of the turf fertilizer and 1 cup of the potassium magnesium sulfate per 100 square feet of surface area around the plants. Fertilize at least a 10 foot diameter area around each plant and as they grow this area can be expanded accordingly. Repeat 4 times per year, or possibly more if the soil is very sandy.
Thanks for the question. Please stop in again soon!
