I planted two of these seedlings around one month ago, and the leaves have gradually curled upwards along the edges and developed dark mottled areas. A couple leaves have a whitish cast to the bottom third of the leaf, but none have dropped off as yet.
The clay soil was amended heavily with commercial composted humus, and mulch is covering the 2 X 3' area. Is this normal?
I have one or more at the Valley, and have been responsible for the care of hundreds (thousands?) more. Of course, this is down here in the Ohio River valley and central KY area.
In paying attention over the past few decades as various diseases and insects have wreaked havoc on dogwood populations in landscapes and in native populations, I've learned by reading, listening, and in practice. Proper siting and early care in establishment pays huge dividends toward a long-lived healthy specimen.
