Why Mulch Matters

Mulching is one of the most beneficial practices for a healthy garden. A proper layer of mulch—usually wood chips, bark, or compost—serves multiple critical functions:

  • Moisture Retention: Mulch slows evaporation, keeping soil moist longer during hot days.
  • Weed Suppression: A layer of 2-3 inches blocks sunlight, preventing most weed seeds from germinating.
  • Temperature Regulation: It insulates the soil, keeping it cooler in summer and warmer in winter.
  • Soil Health: As organic mulch breaks down, it adds nutrients and improves soil structure.

Pro Tip: Avoid "volcano mulching" (piling mulch up against tree trunks). Keep mulch 3-4 inches away from stems and trunks to prevent rot and pests.
