I’m letting the Yellowwood tough it out. Previous years of seeing leafdrop on this tree make me think this is a tough tree, and will make it fine. The salvia is a spare plant out in the distant, neglected part of the garden, far from a hose. She will have to make it on her own. The Amsonia I will force into dormancy by pruning off all the foliage at the ground. Experience has taught me I can rely on her emerging next spring even after such treatment.
