- Use with Mulch
The most effective use of Preen Garden Weed Preventer with mulch varies
depending on the situation.
If you are top dressing 1 to 2 inches of mulch over existing
mulch, apply Preen Garden Weed Preventer before you add the new
mulch.
If you are mulching 2 to 3 inches for the first time over bare
soil, it is preferable to apply Preen Garden Weed Preventer to
the soil first. If weeds appear, it is likely that there were
weed seeds in the mulch. In this case, remove these existing weeds,
apply Preen Garden Weed Preventer, and water or rake it into the
top layer of mulch.
If you have already mulched, Preen Garden Weed Preventer will
still be effective if applied on top of the mulch. Simply sprinkle
Preen Garden Weed Preventer on the mulch, and then water or lightly
rake it into the top layer.
