What is the best temperature to keep a Black Olive tree at?
Black Olives love the heat. The black olive is native to the Caribbean. It hates being colder than 70F at any time – keeping it warm will keep it happy. ^ TOP Q. While on vacation my ficus bonsai dried out. I have been watering it alot but new growth just withers up. Reviving a ficus. If the trunk is still alive the best course of action would be to keep the tree warm and not over water it. Trees with very few or no leaves use much less water than a tree fully leafed out, so water it less frequently until it leafs back out. It may take 8-12 weeks for the tree to leaf back out. But ficus are pretty tough so have patience.
