In the lastblog, I wrote about my decision to not plant any vegetable plants this winter season.  I instead opted to plant cover crops since it was already late in the season, and I have limited time for garden maintenance over the next few months. Plus, cover crops provide other benefits to the soil in my raised garden beds, such as increasing nutrients and organic matter, reducing the chances for erosion, minimizing compaction and improving air circulation, suffocating and suppressing weed growth, AND providing some visually appealing color in the garden throughout winter.

I purchased a mix of organic cover crop seeds and planted these in late-November. Once the seeds were in, we headed out on a road trip to Oregon for some play. When we returned, I was happy to find a full bed of healthy seedlings poking their little green heads out of the soil: What a beautiful sight!

The mix of organic seeds I purchased contains nine varieties of cover crops. I did a little research to better understand the growth cycle of these plants and when they would go to seed. As I noted in my lastblog, I want to avoid having the crop reseed and spread throughout my garden. I discovered that the seed mix will grow and flower simultaneously in a few months, so I can sit back and relax a bit before I even need to think about preparing for the spring season.

There are many choices when it comes to cover crops.  This is just a quick outline of good ones for our local Solano County.

I am looking forward to watching them grow and knowing that they are preparing the soil for spring and summer veggie gardens in the future.
