I have a potted Fig tree, I put it on my balcony, which is northeast facing on the 28th floor. What I could do to make it grow better? There are a couple fruits in May but they has not been growing any bigger since June, and now the leave are turning yellow and falling. Would it helps if I spot light the tree? I have a southeast facing corner inside my apartment, will this be a better location for the fig tree? If so, any advise to avoid insets invading my apartment? I am very new to planting, and the tree is given to me as a gift. I would appreciate any advice, thank you.
