salvia guaranitica leaf disease question
Has anyone had a problem with leaves on their guaranitica (I am having the problem with Argentine Skies) turning from bright green to a pale lime color starting on the edges of the leaves . Eventually the whole leaf gets pale, some areas on the leaf turn brown, then the leaf shrivels up and fall off.
The plants rarely bloom. New growth looks normal, nice and bright green, but the leaves soon turn a pale blotchy pale green color. No one at the local nursery can figure out what the problem is (Natural Gardener in Austin). I tried spraying last year with insecticidal soap and also an oil of some type that is supposed to be nontoxic but didn't work. The plant freezes back every winter but the new growth always has the same problem. I am ready to dig them out to throw away unless someone has a suggestion. Thanks!
