Wilt Pruf
One of the most effective ways to reduce excessive moisture loss in plants when they are under stress is to apply an anti-transpirant called Wilt Pruf.
Available at your local independent lawn and garden center, Wilt Pruf is a safe to use, non-hazardous, organic and biodegradable natural pine oil emulsion that when sprayed on plants leaves a clear transparent and flexible coating.
Ask your knowledgeable garden center representative for assistance and whether a spray application of Wilt Pruf will help your plants this season.
