Wilt Pruf is sprayed over the foliage and stems of a newly planted tree, where it dries to a clear film that slows water loss while new roots grow out into the soil. It works alongside regular deep watering rather than replacing it, and one application typically protects for three to four months.

Why does a newly planted tree need help holding water?

Because transplanting leaves a tree with a small root system that cannot yet replace the water its leaves and needles lose, a stress known as transplant shock. Wind, heat, and strong sun widen that gap, which often shows up as wilting, scorched leaf edges, or browning needles.

When and how is Wilt Pruf applied after planting?

Soon after the tree is planted and given a deep watering, on a dry day when the spray has time to dry on the foliage. The spray covers leaves, needles, and stems evenly, undersides included, since the film protects only the surfaces it coats. A tree planted in fall can be treated again before winter at the stronger winter rate.

Should a new tree get ready to use spray or concentrate?

Either works, depending on how many trees are being planted. Unlike the concentrate, Wilt Pruf Plant Protector Ready to Use Spray needs no mixing, making it practical for a single new tree. Where several trees are planted at once, Wilt Pruf Plant Protector Concentrate is diluted 1 part to 10 parts water during the growing season, or 1 to 5 for winter protection.
