Wilt-Pruf® Guards Against Moisture Loss Year Round!

WILT-PRUF® is a natural product derived from the resin of the pine tree, applied to plant leaves to reduce transpiration of moisture. To read more about the properties of our product, please click here.

Wilt-Pruf® offers various sizes of Concentrate containers and a convenient Ready-To-Use Trigger Sprayer, which are not damaged by freezing or thawing when stored.


When evergreens have been exposed to extreme drying conditions such as frozen roots in the winter or hot drying winds in drought stricken areas, they might not have enough moisture in their foliage to survive without help. Wilt-Pruf® gives them the added protection they need during these long severe periods of water stress.

  • Protects  plants against cold drying winds of winter and hot drying winds of summer.
  • Protects  plants when roots are frozen in the winter depriving them of their normal moisture intake as well as during periods of drought.
  • Protects  tender transplants while their root systems are developing. Tubers and bulbs do better in storage when first sprayed or dipped with Wilt-Pruf®.
  • Protects and extends the life of Christmas trees and wreaths by reducing moisture loss.
