When to Grow A Spring Cover Crop

Cover crops are the perfect way to prepare your garden for a plentiful fall harvest if you are skipping the early spring vegetables this year. Instead of letting the weeds go rampant, reduce and suppress them with a cover crop. If your garden isn’t feeding you, it might as well feed itself. Right? Spring cover crops are meant to help boost nutrients in the soil, suppress weeds, increase biomass (organic matter), and attract pollinators and other beneficial insects. You don’t need to look at a garden full of weeds before you are ready to start planting in the summer.

To help you plan and prepare your garden for the best season yet, we have provided a list of cover crops based on the benefits they provide. To get started, plant your seeds by broadcasting them over your home growing space. Alfalfa, barley, and spring wheat do well when planted in the early spring (mid-March to early April in areas without a frost). You should wait to plant all others until just past your last spring frost date for your location.

If you are interested in learning more about what cover crops or don’t know where to start, read our “What Are Cover Crops And Green Manures Used For?” article. The big reason we use cover crops is to prevent soil erosion and restore soils. This does not only apply to large farms, it is also essential in the home garden. Cover crop practices can also be used to feed animals such as chickens.

For a complete look at how to grow individual cover crops, we recommend reading through our free cover crop grow guide for advice tailored to each crop. Here you will find many of your questions answered.
