I have 3 paper barks and 3 japanese maples. The paperbarks I received a few years old and this is my first season with them, and they don't seem to be doing well and have stagnated. I originally had them in a poor soil mix that was staying too wet, so I repotted 1, waited a month or so and it didn't get worse so I repotted a second and the 3rd is still in its original mix. All my maples don't seem capable of putting out new growth, it just turns black and dies. Additionally, the leaves that are there are spotty and grey, and I don't suspect anything pest wise because I have been spraying them intermittently over the summer and it hasn't helped them improve. The Japanese maples' leaves turn out black as well, and what small leaves do form are missformed and stunted looking. I repotted both Japanese maples and originally had success and the new growth was healthy, but that's stopped and now none of my maples seem to be growing properly. Winter is coming, and I really don't want to lose these trees. I have tried everything but it's becoming more and more obvious that I don't know what I'm doing and I really need some help. Thank you in advance, I appreciate it. The paperbarks get a lot of morning sun and then intermittent shade throughout the day. The Japanese maples are mostly shaded with direct morning sun. I dont know if it's a good idea or not, but I grow plants indoors and have it set up for plants this size. Could I keep them inside under grow lights to extend their growing season before winter? I don't know if that would help or hurt them.
