What Is Wrong With My In Doors Lemon

Question

recently our dwarf lemon tree, having previously an abundance of leaves and very young fruit, has lost all its leaves and all but one of its fruit. I have looked through a multitude of books we have and have yet no idea what is wrong.

Answer 1

Unfortunately, your photos did not come through. I have even less information than you have!

It could be a multitude of issues, and likely, is more than one of them. If the light, humidity, temperatures, or soil moisture changes rapidly, or is no longer in a state that promotes the growth of citrus, it will shed all of its leaves and fruit.

Unfortunately, there are a lot of factors to pick through. I would start by using a horticultural grade bulb 100 watts or greater. Do not use cheap LED panels, as they will not suffice for citrus.

Make sure to feed with citrus fertilizers, and plant into a citrus soil to take the guesswork out of preparing for the picky trees.
