Q.Magnesium Deficiency In Date Palms In Winter- How To Treat
Phoenix canariensis in 300 litre bags have been fed in both Spring and Autumn. All good throughout the year until Winter when those Date Palms in 300 litre bags have yellow fronds. The ones in the ground are very green as opposed to those in the 300 litre bags. How do I treat this problem at the cold time of the year and why has this occured when they have been adequately fed in both Autumn and Spring? Is there something about those palms in the bags that makes them suffer more than those in the ground that are looking beautiful. Two thirds of the fronds are affected. The middle fronds are still green at this stage. Would appreciate any assistance. Thanks Sue

Do the bags have holes for drainage? The fertilizer will drain through with the water. Slow release fertilizer will not flush out as quickly as water soluble fertilizer. This article (although about growing in Florida) should help.
