Q.Our indoor avocado tree

Zone Clinton, NJ 08801 | Anonymous added on February 6, 2018 | Answered

We have an avocado tree grown from a pit that is about 4 yrs old. From the floor to its’ top is about 5 and 1/2 feet. Since we live in NJ we put it out in the summer and it grows and looks great. Then we bring it in for the winter and inevitably after a month or so it begins to get a whitish salt look on the leaves and some stems as well as getting brown edges. I could crush a leaf in my hand and most of it crumbles into little pieces. Yet there is a lot of new little leaves. I have looked at the white spots under a magnifying glass and they don’t appear to be insects and you can wipe the stuff away and the leaf looks OK except for the brown crinkely edges. I just noticed it has a bad scale infestation so I’ll treat that with neem oil. But what is the white stuff? We also give our plant old pond water which is not treated with anything. Thanks, Richelle

White deposits could from pests, fungus or even build up of salts from tap water.

Neem Oil is a good organic treatment and works as both an insecticide and fungicide.

I would use distilled water or set your tap water out for 48 hours before using to water your plants. Excess fertilizer can also build up in the soil.
