I plant some bareroot adenium 2 weeks ago and they have started to get leaves. I have them in the sun , and would like to know which is the best fertilizer i should use on them and how soon i can do so also how often I should water bearing in mind that I live in Kingston ,Jamaica. Before planting I had soak them in Superthrive. I read somewhere that I can use superthrive at each water but I am scared to that I may loose beloved plants. Also I brought these plants on sale and caudex in the 2nd picture lost it stem , will it grow back? Thanks for your help.

Your plants should be fine, give them a little time to adjust. Water only when really dry and give them full sun after they have adjusted. You can definitely use superthrive regularly.
Your 'tipless' plant will probably make a new branch or two. If not you can try grafting new branches on to it after it has adjusted and started growing.
