I'm growing a tree in a pot inside...it's too cold in the winter to try to grow it outside. I realize I'll probably never get fruit from it, but it's a nice tree to have for decorative purposes. It's over 4 feet tall now and is 9 months old. It has extremely droopy leaves. Otherwise it looks fine. The leaves are a nice uniform dark green. The pot is a 13.9 diam. x 10.75 H self-watering pot. I'm guessing this is about 5 gallons. I'm not sure if I should transplant it again...I've already transplanted it once. It has a moon valley houseplant in with it (see my previous post). I could not detangle the roots when I transplanted so they are still living together in the same pot. Anway. I would like to see the leaves lift.
I also have another young tree that's about a month or so old now. I've had to prune some leaves from it already due to browning on the edges. I have read that it is a potassium deficiency. Does this sound accurate? If so, should I use some fertilizer sticks, or something more specific? Any help for my two trees would be appreciated.
