It feels almost depressing closing the gardens for the summer. We have made a little experiment to how we can get better soil. Last year we sowed cover crop to manage soil and nutrition eruption, although I do not think it worked, because despite our flourishing gardens, the soil felt extremely hard and impenetrable. Organic farmers (in Denmark at least) sow cover crops in autumn to have their fields remain green throughout the winter.
So, this year we are putting out compost on the beds and we made two test beds; one with cover crops and one with compost to see if we can see any difference. The reason for using compost is to give the soil a better structure along with more nutrients to the future vegetables. I hope it helps.
What do you guys usually do when you prepare your garden for the winter?
