I planted this grafted fuyu persimmon two months ago. About a month ago it started budding and has been putting out large, healthy stems and beautiful new leaves. Just overnight about half the tree started wilting. Mostly the bottom leaves are soft, curling, drooping and have irregular brown patches. The top few stems are still looking very good (except for one tiny brown spot). I've never had a plant go from vigorous, healthy growth to almost completely blighted within 24 hours. Could this be transplant shock? It's newly planted, but could that occur even after having an initially strong 'leafing out?'
It's on an automatic watering system. About 10 minutes steady trickle every other day.
