The raised beds are done. They are all filled with soil mix. The last one got about 2/3 soil from where the neighbor built a road on his easement on my property. It's good soil, unimproved and fallow. That got mixed with some raised bed soil from an old bed that has been improved with lots of compost over the years. I added some wood ashes and crushed eggshell to the mix.
The middle bed also settled, so got a wheelbarrow of that same soil on top of the prior mix. I added it on top of the maple leaf mulch, which I want to compost itself. Both beds will get a leaf mulch for the rest of the winter. I hope the earthworms will like that and do their thing.
The first bed was planted with garlic after I filled it in Sept or Oct. These are the big, "Music" garlic, and also some others. One row had germinated shortly after, but the most did not. Now they are poking through the soil. Winter wont hurt them. Currently they are getting all of the coffee grounds, which in my case is quite a bit. I used to collect coffee grounds from Starbucks, which sometimes they were nice about and sometimes they were put off by that. With the pandemic, I haven't been to a Starbucks in a year. So these are all from my own coffee pot. They also got quite a bit of compost mixed into the upper soil layers, which I figure they will like.
I also salvaged some garlic plants from an old raised bed, planting them in the new one. I don't know how they will do. But if they grow, that's good. If they don't, nothing lost.
I think these taller raised beds will benefit my gardening a lot. They don't take nearly the amount of leaning and crouching and back-straining. They were still a lot of work to fill. That is an investment into a gardening future. Having three beds, one gets garlic, one gets peppers and pickle cukes, and one gets scallions and leaf crops, or bush beans. That makes a good rotation, one year on / two years off for each crop.
So far, I like this style of raised bed better than any other that I've tried. They are less heavy work to put together. Boards take less garden real estate than cement blocks, although there are advantages to those.
