How to Apply
Bulbs and Perennials: Spread Preen Mulch Plus over the area to a depth of two inches. Do not plant flowers directly into garden mulch. If additional planting is desired after Preen Mulch has been applied, first remove the mulch from the selected area. Avoid getting treated garden mulch into the planting hole. Once the plant is firmly embedded in the soil, replace the mulch around the plant.
Annuals: After plants have been set in the soil bed, spread Preen Mulch Plus over the area to a depth of two inches. Make no more than one application per site per year.
When to Apply
Preen Mulch Plus contains pre-emergent herbicides and for best results, remove all weeds in the beds prior to applying the garden mulch. You may apply anytime in the spring and fall after renovating beds, but for best results, apply Preen Mulch Plus after flowers and ornamentals have been planted into the soil. Do not apply over flower seeds.
For ornamental bulbs, apply 2 to 4 weeks after planting, or before or after flowering. Do not apply to bulbs when flowering.
How Much Mulch Do You Need?
Although most mulches temporarily suppress weeds when applied at a minimum depth of 3 inches, only Preen Mulch Plus, with its weed barrier technology, blocks weeds for up to 6 months when applied 2 inches deep.
When applied according to label directions, one 2 cu. ft. bag of Preen Mulch Plus covers 12 sq. ft. at 2 inches deep. Other brands recommend 2 cu. ft. bags be applied at 3 inches deep, which will cover 8 sq. ft. With Preen Mulch Plus, you'll use fewer bags to cover more space than other brands and get much better weed control.
