I live in New Jersey and its still pretty cold here I just got a white serissa and a barbados cherry maybe 3 weeks ago. I am having some problems right now
the serissa is turning its leaves yellow and losing them pretty fast, and the barbados is brittle and also losing leaves fast. I have them on the window sill of my bay window where they receive direct mormning sunlight and indirect sun the rest of the day I bought a moisture meter meaturing 0 to 10 and ive been keeping them at a 5.
I was wondering if I should repot them with better soil than what they came in and if I should maybe get the gro lights and is miracle grow good for them? Help I'm new to this and I really don't want to kill these trees
