Last summer I germinated an avocado plant, it did Ok through the winter
but now is drying out from low humidity. I've been spraying tap water on
it but it's turning the leaves yellow like the minerals in the water is
hurting the leaves.

I plan to start using distilled water to spray on the leaves, but I was
wondering if there is something I can put on the leaves or spray on to
keep it hydrated better?

Any suggestions?

Thanks
