Growing Oats as a Cover Crop

Although growing unprotected crops over the winter is not much of an option for those living in colder climates, for those living in more mild climates - winter gardening is can provide many opportunities. Growing over the winter can provide the opportunity to incorporate additional fertility or to grow additional crops. Fertility can be added through compost and amendments or through growing a “green manure” cover crop.

 

 

 

Cool wet conditions in the maritime northwest can make interesting challenges for growing over the winter. Especially if slugs persist and squirrels dig everything up. Slugs mow lots of lower leaves down while squirrels love to bury and dig up all manner of things in my garden on a daily basis. Because of these factors, some of the best things I can grow are larger cover crops. However, in my 2019-2020 winter garden, I chose to grow some oats. Because I had previously grown fava beans, I felt changing to another, shorter crop would be good.

 

 

 

At first this was true. The oats were relatively small to begin with. However, given time, the oats grew to be at least as tall as the Robin Hood fava beans. At the end of the season, I cut down all of the oats in the garden except those which were the most shaded. I left those to grow a seed crop for the next time I want to grow oats as a cover crop.

 

Looking back on the experience, I’m glad that I decided to use oats as a green manure this last year. They were relatively easy to cut down and enabled me to keep my garden weed free. In moderate climates, it can often be a situation of “seed it or weed it” meaning that if the gardener does not cover the ground, weeds will quickly spring up.

2020 in the Backyard Garden

What a year 2020 was - even for my backyard garden. Prior to winter setting in, I stocked up on leaves. When I say stocked up, I really mean it. 2019 was the year of leaves. I probably gathered at least 50 bags of leaves. I had so many leaves that I had leaves stored at the side of the house, waiting to be put into the compost. This year I decided to grow oats as a cover crop.

Meanwhile, the squirrels kept either digging up or eating my lettuce plants, no matter what I did – so I eventually decided to grow my lettuce on our upstairs balcony with aluminum foil around it. I’ll discuss the joys of this experiment later. As the weather warmed, I brought out some banana trees, which I nurtured in my greenhouse along with some trial cucumber varieties. While growing out these varieties I also started my spring transplants in 2 inch soil blocks in the greenhouse.

Clearing the garden for the summer crop

 

 

 Over time, the lettuce bolted and the summer cucumbers were put out. I grew a round Carosello variety this year called Carosello Tondo Massafra. I transplanted the bananas off to the side yard where I had previously grown sweet potatoes and tomatoes. Unfortunately, due to further squirrel damage (a child chose not to heed my request to not give the squirrels nuts), I had to set out another round of Carosello Massafra transplants. This really ate up my light hours and made my Massafra harvest last through late July to early August.

As our new neighbors were growing very tall corn, my August garden was really shaded my garden in the afternoon. Unfortunately, powdery mildew was already starting to kick in near the end of the season when I decided to transplant the long dark Armenian cucumber - so it was only a matter of time before the plants succumbed to its effects.

Meanwhile, in the small corner garden, I grew out my little banana trees and Taxi tomatoes. Both the banana trees and the tomatoes suffered until I applied some biologically-based bacterial fungicide on the plants. Then they went from dying to thriving.

 

This whole time, I was also trying out cucamelons. Not that I am a huge fan, but since a lot of people seem to like them, I decided to try growing them out.

Around June, I put out sweet potato sets out of my Dingess purple sweet potatoes which I later harvested after Thanksgiving. In the autumn of 2020, I was unable to harvest as many leaves, due to the fact that they all comedown at once. We had a combination of high winds and cold nights that brought all the leaves down. The neighborhood in which the leaves fell called up the city and they were quickly removed before I could gather very much, so I am glad that I had plenty of leaves to compost from my 2019 leaf harvest.

Another look at the harvest

 As for my winter garden, I decided it was finally time for a rest. I had tried planting out some Bolero carrots, but the pressure from squirrels was too great. Instead, I would compost my garden and focus on finishing the cucamelon harvest and seed processing.
