QUESTION: My fox palms new prawns are very green but VERY quickly turn brown and the stem seems to be spotted.

I have fertilized and added magnesium. What is needed for these trees to look healthier.

Is fertilization every 6 months sufficient.

ANSWER: Hi Debra, the spots are normal, its a phenomonon with Foxtails, many think its insects at first; the fronds turning brown howver is a problem. How long have they been in the ground? let me know..Nick

QUESTION: They are almost 4 years old

Answer
The fronds turning brown is usually a problem with too much moisture at the root ball, make sure they are not being over watered, and fertilizing should be done 3 times a year with a well balanced palm fertilizer with all the micro nurtients such as magnesium sulphate and iron etc. 4 year old palms this time of year can pretty much be left alone as far as irrigation goes, only during the dry season do they need attention.
