Late as usual

Hello dirty minded peeps! Well, as usual, I’m a bit late in my planting schedule. I was hoping to start my winter garden last month but have been swamped with other projects. This would be a poor time for most of you out there to start with the impending frost heading your way, but to folk living in SoCal it’s a moot point! This will be the first time I’ve ever tried doing a winter cover crop that wasn’t specifically just for the dinner table.

What is a Winter Cover Crop?

A winter cover crop consists of plants that are perfectly designed to repair the soil after all the leaching of nutrients that occurred during your spring and summer growing season. Not only do they add precious nitrogen to the soil, but many of the plants roots are perfect for reaching deep into the earth to break up the soil that your normal crops can’t reach. They then pull up the nutrients to make them accessible for the next spring/summer growing season. Then all you have to do is turn everything into the soil for a perfect green manure. It’s a win win situation! For more information on nitrogen fixing plants, check out my article on legumes!

Prepping the space

So the first thing I needed to do was to get the garden ready. I was getting tired of the many rows I made before and how inaccessible the whole garden was when everything was growing madly. I decided that I wanted to consolidate everything into one, easy to get around, raised bed. I had a bunch of scrap cedar planks left over from an exhibition at The San Diego Museum of Art that were used for our Piranesi exhibit as rustic wood flooring. I used some of it to build my chicken coop, a compost staging bin as well as other yard projects. One of the many perks of working at the museum is repurposed materials!

I began by pulling all the weeds out, removing the spent summer crops and raking the soil into a pile instead of the 4 rows it used to be. I had to move the micro drip irrigation in order to do all of this.

I then used a level to create some irrigation slopes that I wanted to do for so long now. See that green hose in the corner? Well, it’s attached to my rain barrel which collects all the water from my washing machine. I use safe laundry soap that actually adds some beneficial nutrients to my soil. That, and the nutrient rich dirty underwear water makes for a great sustainable water use system! Now the water will flow all the way around my raised bed and deposit itself in the strawberry patch at the end of the line. Kinda like this…

As you can see, I’ve already been adding the cedar planks and supporting them with some simple 17″ pine stakes. I wanted this bed to be easy to remove if I ever want to go back to the row system again. This way at least, the soil can all be fixed in one nice package. The cedar planks simply slide into the stakes as such…

I used two rows of cedar on this side because of the slope I have off of the back of my garage. I also left a channel between the cedar planks and the concrete slab so the gray-water irrigation has a place to go as it seeps underneath into my garden. I’m trying to keep this very low-tech and very cheap. The only thing I bought for the project were the wood stakes for $3.27 at the Home Depot as well as manure and mulch to add to the soil.

Here we have the finished cedar set up ready for the soil amendments.

Now I raked the soil to a more level state and added two bags of manure and 3 cubic feet of soil enhancing mulch.

Mmmm, stinky! This may have been overkill, but I really want to have better yields next season as well as get this late planted winter cover crop a nice boost of nutrients to grow big and strong. I’m serious about soil amendment! Look how serious I am about it…

And now it’s time to till the soil to mix everything together.

I really need a photographer with me when I work. This could’ve been a sweet action shot but I was too dirty to go inside and get the tripod and remote for my camera. So this is what you get. A staged and tightly cropped image of me about to till. Use your imagination and picture me tilling away. I’ll wait…

We reap what we sow.

Great! All done. Now to broadcast my seed mixture. I went with the Sustain Seed Winter blend from The Dirty Gardener available on Amazon.





Here’s the mix of my winter work force. I may add radishes as well because I’ve read that their roots penetrate deeply into the ground. I’ll see what the above ingredients do first though. I simply broadcast the seeds by hand after mixing up the bag to get a nice even species mix.

I then lightly raked the seeds into the first inch of soil so the birds don’t eat up all my crops!

Once that was done, I waited to see if anything would sprout up right away like Jack and the beanstalk. Spoiler alert, it didn’t. So it goes. The next step was to adjust the micro irrigation set up so to better fit in my new garden space.

Much better! I use 1/2 gallon drippers every 16″ inches as well as a few adjustable sprayers that move around as needed. This bed is officially ready to grow! But I’m not done yet. I also wanted to do something to the pathways around the bed to help save some future weed headaches. This is also a new method for me that I’ve been reading about on other blogs. Using wet cardboard and straw as a weed barrier on the footpaths. I hope it works, because I’m growing weary of all the weeding I have to do in this garden.

First thing I did was to soak the cardboard in water. This helps make it permeable and easily conforms to the surface of the dirt. If it were dry, all the water would move off of it like a shingle. I want to incorporate it into the system and allow it to break down over time.

I began layering the cardboard around making sure it overlapped everywhere. If any sunlight gets through, then so do the weeds!

I left spaces around my existing grape vines as well as a single carrot that survived the pig apocalypse last month. Ha Hamilton! You missed one! It’s important to not cover these areas with cardboard so you can add fertilizer when needed. Eventually the cardboard will break down and the grape vine roots are all over the place now anyways. Another reason why I wanted to have a raised bed!

After I finished with the cardboard, I added a layer of straw to help retain moisture as well as give my knees a comfy bed when I work in the garden. It also gives the whole space a cleaner look.

And voilà, there you have it! I’ll post some photos when things begin to grow due to the fact that I will be watching it daily. A nice watering and it’s germination time. I’m really excited to see the results of this winter cover crop and I hope it bears much fruit next growing season. If you live somewhere where winter is upon you, you can start this project in the early fall as soon as your summer harvest is completed. Let it grow as long as you can, or let the frost kill it off. Then chop it down and leave everything on top of the soil or till it in. the winter snow will take care of the rest and come next spring you will have nutrient rich repaired soil ready for your veggies!

In my Mediterranean climate, I’ll just let it go to seed or harvest whatever fruit it bears. If I do let it go to seed, I will save the seeds for next fall and cut out the middle man. Well folks, that was this weekends project. I could’ve done more but the Halloween festivities have somehow made me weaker and in search of much aspirin, water and couch naps. Getting old really takes a toll on you. Until next time, keep those hands dirty!
