I have two 10-gallon Smart Pots that I used last year (very successfully) to grow bell peppers and microgreens. I used Fafard organic potting soil (http://fafard.com/products?productID=165) in both. I added a little bit of fertilizer during the growing season (fish emulsion, I think). What should I do to prepare the pots for the spring/summer growing season? You can either answer the question or direct me to an earlier post that addresses the same issue.
