Description
Available at Lowe's and independent garden centers nationwide!
Preen Mulch Plus is a premium quality garden mulch combined with two long-lasting pre-emergence herbicides. One application of Preen Mulch provides 6 months’ control of broadleaf weeds and annual grasses in flower and ornamental beds. Plus, it helps landscaped areas retain moisture – protecting your plants, trees, and shrubs from extreme temperatures.

Preen Mulch Plus provides increased weed control vs. ordinary garden mulches, when used as directed. This garden mulch contains only natural forest products and contains no recycled waste wood. These materials are ideal for garden mulches because they naturally degrade over time, turning into valuable organic matter.
Application
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.
