The benefits of using a living mulchThere are many benefits of growing living mulch in your garden. Living mulch can provide shade, help retain soil moisture, control weeds, help reduce disease issues, and help to control some insect pests. The best reason to use living mulch is because most cover crops, such as clovers, feed nitrogen into the soil which in turn benefits your vegetable plants. Typically the cover crop is left in place until the end of its life cycle, and then is tilled or turned over into the garden soil for the next growing season. Using a living mulch can also give your garden a better appearance. Talk about getting your money's worth! Living mulches are not appropriate in every situation. Make sure the cover crop is complementary of the other plants around it before planting. Never use a cover crop that is susceptible to the same diseases as the main vegetable plant.
How to plant a living mulchLiving mulches can be planted before or after the main vegetable crop. It is generally easier to plant the cover crop four to five weeks after the main crop has been planted. Here are some steps to establish a living mulch:
- Make sure your vegetable garden is free of weeds before planting any vegetables or cover crops.
- Let the main vegetable grow alone for four to five weeks. This will help keep the cover crop from competing with the vegetable.
- Take care with planting cover crop seeds. Do not broadcast the seeds as this could lead to the cover crop dominating the garden. Take care when planting cover crop seeds between planting. Sow seeds in dedicated areas.
