This wilt pruf concentrate plant protector acts as a protective coating, holding in moisture in plant foliage and stems, substantially reducing water loss during periods of plant stress. Excessive moisture loss in plants causes stress, shock, wilting and plant failure. It strikes during periods of drought, or when the plant roots are disturbed during transplanting. It also occurs in winter when drying winds and frozen ground deprive plants of their natural moisture intake. This product contents 32 ounces.
