We finally grew some beautiful garlic in the green house. The soil was really lacking and it showed. Never take good soil for granted. We had basically crumbled up rocks when we started. There was virtually no organic matter to hold water. So, we have been composting for 3 years and adding it to the beds to get something close to soil. In addition, I have been bringing home buckets of used coffee grounds from the local coffee shop and adding to the beds. Coffee grounds add much needed nitrogen to the soil. This garlic is powerful!
