Delurking to ask if anyone has used coffee grounds as fertilizer for the desert rose. I have access to alot of grounds from work and was just wondering.
Hello and welcome to the forum.
I have heard of using coffee grounds as a fertiliser on the palm forum and also for helping to rid palm scale. They are a good source of nitrogen, but one thing against them is their ability to hold water...something you don't really want to do in the case of an Adenium as they need especially well draining soil. If sprinkled too liberally they also tend to go mouldy under certain conditions...also not a good idea either. So yes, they do have their uses, but I wouldn't think they are good to use with your DR's.
