My notes from the Extension Agent on caring for our large Sylvester: "Palms need slow-release fertilizer. Use Lesco 8-2-12 from John Deere Store at 1201 Thomas Avenue, Leesburg, (352) 748-6555.
Apply 1.5 lbs. per 100 sq. ft. of canopy every two months from March to Sept.
Broadcast the fertilizer out under the canopy to the drip line; Sylvester roots can spread 50 ft.
Don't buy fertilizers with oxides. Don't use Epsom salts for magnesium, can cause potassium deficiency. Don't use iron oxide or magnesium secrete. No cow manure or fertilizer stakes. Palms need boron.
You can use palm fertilizer (8-2-12) on turf and shrubs, as well. If using on shrubs, apply March, July, September. Do not use any other fertilizer on the grass near the palm."
