I'm getting ready to prepare my raised garden beds for the fall and winter. Last year, I mostly used leaf mold, but in one section, I planted mustard greens. In the spring, I added compost and some fertilizer throughout the season. Overall, things did okay, but I noticed some beds were a lot more productive than others. I'm curious about what techniques or materials other gardeners find most effective for improving soil fertility over the cooler months. What are your go-to methods?

I've had great success by mixing in native soil into my raised beds. Initially, I used topsoil mixed with compost and some chicken and rabbit manure, but the plants struggled because they didn't have anything to anchor their roots in. After digging out a fish pond last winter, I added my excess native clay soil to the beds, which really helped. After soaking and screening out the rocks, I mixed this clay into the organic materials, and the plants thrived this year! I think the clay gave the roots something to grip while also introducing beneficial microbes essential for plant growth. This winter, I plan to just add rabbit manure and chopped leaves.
I make my own compost and apply about an inch each fall to all my beds. This way, I can grow through spring, summer, and fall without the need for extra fertilizers. It really boosts soil fertility and keeps everything healthy!

That's awesome! I make compost too, but I can't keep up with how much I need for all my beds. Any tips on boosting production?
