It has been a month now since i planted my bareroot desert rose , and they have all lots of leaves , just want to know when I should I start fertilizing, and what is best fertilizers to use. I am in Jamaica and the ones mostly available here are 20-20-20 and MiracleGro that are water soluble and then there is Osmocote in both 19-6-12 and 14-14-14 slow release. Some of my branches are very slender.
