Citrus Trees

Leaf Curl

Zone Norwich,UK | Dillydear added on February 3, 2018 | Answered

I have a small citrus australasica in a pot. It is indoors at present due to cold weather & frosts. The leaves at the outer edges of the plant have started curling up and although still looking green they are dry and crumble. I can find no traces of a pest infestatation. The soil is moist but not soaking wet

This is the natural process indoors. The lack of humidity and direct, unfiltered light causes it to go into a semi dormant state. You can supplement light with about 200 watts of horticultural lighting, and either put a humidifier next to it, or spray a few times daily with a fine mist. This will help out.
