Hello, I am wondering if my tangerine tree is growing properly. It is a little over 5 years old, has 13 leaves, is 10 inches tall and 1/8 of an inch wide at the base. Two of the lower leaves have fallen off in the past year and a half because the leaves above it blocked them from recieving any light. I water it twice a week and keep it indoors all year round. I am wondering how many nodes my tangerine tree needs before it will bear fruit. Also, I am wondering how to train it to be outdoors in the summer. I would also be interested to know the ideal conditions to keep it healthy and how fast it should be growing.
