Mulch: Multitude of Benefits

Reader Contribution by Charlyn Ellis

The Willamette Valley, usually known for it’s darn near perfect summers—dry, breezy, in the eighties with cool nights—has seen two serious heat waves this summer. One came at the end of June, the second at the end of July. Both were problematic for crops, as they came right when many young transplants were settling into the fields. My own small scale fall and winter garden went in about four days before the second heat wave. How could I keep them alive in the blazing afternoon sun when their roots were not reaching deep into the soil? I mulched. First, I worked all of the residual mulch from the early potato crop into the bed. Then I nested each start in a base of straw mulch laid over the ground and soaker hoses. They all came through. Mulch. Straw, leaves, winter cover crops, cardboard or woodshavings … it’s useful stuff. Placed neatly around the base of young plants and later worked into the soil, it has a multitude of benefits.

1. Mulch keeps the weeds at bay. If the garden bed is thoroughly weeded before the mulch is laid down, the organic matter keeps new weed seeds from sprouting as quickly by blocking the light. And, when they do sprout, they are often more loosely attached to the soil and thus easy to pull.
