Our recommendation is to use the 14-14-14 wax coated slow release fertilizer, which includes all your minor elements.

This fertilizer lasts up to 3-4 months and it will not burn the plant due to the wax coating and slow release. There are many other
fertilizers on the market and some state “fast release.”
This will green up your plants quicker and for a shorter period of time, but they can also burn/ruin the foliage on many softer leaved plants. 14-14-14 slow release fertilizer is safe on all plants including palms and citrus. Great all around fertilizer!
