Wilt Pruf is a natural nontoxic product derived from the resin of pine trees. Wilt Pruf forms a soft, clear, flexible film on treated plants. This film protects plants from drying out, drought, wind burn, sun scald, winter kill, transplant shock and salt damage, while at the same time allowing them to grow naturally. May be used on evergreens, trees, shrubs, turf, flowers, vegetables, bulbs, houseplants, transplant and dormant growing plants.
One application should last all season (3-4 months). May also be used to extend the life of Christmas trees.
