A thriving wisteria is suddenly drooping. Could the water from flushing and cleaning cement tools have harmed the roots? About five days before the drooping, a small concrete walk was made at a distance away from the wisteria plant. But when the wheelbarrow and tools were cleaned, they were uphill from the plant and were generously sprayed with a hose. Some of that water (alkaline) probably seeped into the ground. Two ideas are being tried: 1) flood the area to dilute the alkaline water, and 2) mix a solution of Mir-Acid and apply in a patch between the cement water and the plant. Is it too late?
