Mulch helps retain water around plants and adds a layer of organic material. Mulching every year improves the soil in a garden.
Gardening expert Don Engebretson gives mulching tips.
  • Put a one to two-inch layer of mulch on vegetable and flower gardens after plants have emerged in the spring.

  • Mulch slows evaporation of moisture from the soil, which means less watering, and keeps roots cooler and less stressed. It also acts as a weed barrier to block out weeds.

  • Mulch helps maintain soil structure by keeping topsoil from cracking in the heat. It breaks down over the season and adds organic matter to soil during the winter.

  • Mulches range from inexpensive to free, and there is a wide variety of materials that can be used as mulch.

  • Coco-bean husks are available by the bag. Water after applying, and they form a porous crust and make great mulch. They're also easiest to use in tight areas.

  • Black plastic works for vegetable gardens and warms the soil quickly as well as acting as a weed barrier.

  • Grass clippings are free, and should be bagged during the first few times the lawn is mowed in the spring. Do not use the clippings on a garden if weed killers have been applied to the lawn in the past.

  • Mulch made from shredded leaves is also free, and can be made using a leaf chipper or lawn mower. However, leaves are not good for use in windy areas.

  • Compost is also free and is the best mulch for adding organic matter to soil over time.

  • Avoid mulching with hay, especially rye grass straw. It has too many seeds that will eventually sprout and could create a serious weed problem in the garden.
