• Gardens Love Organic Mulch
    Friday, July 18, 2008 at

  • Organic mulch offers tremendous advantages when placed around your garden flowers and vegetables. A 2" layer of mulch prevents moisture from evaporating, so less watering is needed. Mulch blocks weed growth and reduces the amount of insects and other pests.

    Mulch acts as an insulator to protect soil from extreme heat or cold so a layer of mulch around your plants is a smart idea year round. Plus, mulch makes an attractive groundcover. Mulch comes in a variety of colors from blond to red to dark brown (depending on the source wood). The size of the materials ranges from 1/4" to 3".

    Organic mulches contain only natural wood materials. Depending on the blend, mulches can include fir, buckwheat hulls, redwood bark, evergreen boughs, hops, ground corncobs, sugar cane and cottonseed hulls. Avoid buying mulch that contains hay, manure and straw. These types might contain weeds.

    Mulches that contain more wood will provide fewer nutrients and decompose slowly. Softer mulches will provide more nutrients but decompose more quickly.

    How to Lay Down Mulch

    1) Apply a 2" to 4" layer of mulch over the planting beds of already established plants. Leave a 5-inch radius around each plant. Do not put mulch over recently planted seeds because it will hinder their growth.

    2) Rake the mulch every so often to expose new mulch.

    3) The mulch will decompose over time. When only a thin layer is left, add more.
