Why You Should Replace Pine Straw Mulch Annually

Two Reasons to Remove Old Pine Straw

1. Insects: Deep mulch harbors roaches, ants, scorpions near foundations. Dr. Dan Suiter (Urban Pest Management) recommends keeping mulch 12–16 inches from house and replacing yearly.
2. Weeds: Decomposed straw becomes rich soil where weed seeds sprout. Constant moisture grows fungal mats that become water-repellent when dry, blocking irrigation.

Consider these points before adding more mulch.
