Gardentalk – Mulch it!

It’s not just the bulbs and vegetables that are sprouting. Weeds are also making a comeback. One way to slow them down or preclude their growth is by laying down adequate mulch.

Master Gardener Ed Buyarski says several types of mulch can do the trick:

  • Bark or wood chip mulch placed around rhododendrons and other plants release nutrients as they decompose and keeps the soil acidic
  • Layers of recycled newspaper or cardboard can inhibit grass or weed growth for a prospective garden plot or  placement of a planter
  • Seaweed mulch releases nutrients as it decomposes and the salt keeps slugs away
  • Heavy duty landscaping fabric or woven plastic create permanent layers of ground cover
  • Gravel mulch, usually placed on top of landscaping fabric or plastic, is useful for landscaping and lining garden paths
