When the weather is wet and humid, less is more. Apparently, lots of people. Mr. Dodge said he visited many homes this spring where the sprinklers were on either while it was raining or the day after a storm. Too much water encourages root rot and fungus. When the air is wet and heavy, keep the pruning shears in the shed.
Open wounds allow fungi to get in.
Most affected are sycamores and dogwoods. I've seen a lot of wilt in sugar maples. Lou Weinstock, co-owner of Pound Ridge Nurseries in Pound Ridge, N.Y., didn't think this spring was too wet. Plants that are in trouble have probably been planted in the wrong place. The main thing is soil condition.
