No Needles!

Never Inject fertilizers

When cleaning out the cluster of Chinese Fan Palms on the southeast corner of the clubhouse, several ‘bullet’ shaped things were discovered in one somewhat sick looking coconut palm. It appears that someone had thought this was the proper way to fertilize a palm! There are times to inject trees, such as fungicides to respond to Dutch Elm Disease – but this was clearly someone out of the main stream in proper horticulture. Sadly – the side of the tree with the plugs in it is so damaged that the tree is scheduled to be removed.

Well, then, some say “of course not” – inject INTO THE GROUND. Sadly, that, too, is not good plant culture. Why? Here is what the University of Florida Institute for Food and Agriculture has to say:

” Injecting water-soluble fertilizers into the “root zone” of palms is never recommended because 1) water-soluble fertilizers are readily lost to leaching, 2) lateral movement of injected fertilizer is minimal, and 3) injecting any nutrients deeply enough to avoid turfgrass roots will also miss the majority of the palm’s fine feeder roots, which tend to intermingle with turf roots near the soil surface. ” Source:
