I have a Dragon Tree which has yellow leaves which are falling off and I'm not sure if it's too much water or too little! That might sound odd I know, the reason I find it hard to tell is because when I buy plants from Home Depot they are in soil which is also full of lava rocks and so a) my moisture meter won't work and b) I find it hard to tell if it's wet or dry to the touch due to the rocks.
Also.....I should keep a better track of when I water it......I think it's been a while since I watered it so possibly it's too little water but I'm not sure.
Any advice?
