Give these a try. In just 4 weeks you'll have some tasty nutritious micro-winter greens for your salads, sandwiches or to garnish your soups. The Diggers seed mix I used includes beetroot, mustard greens, kale and tatsoi. I sowed them straight into this pot using a good organic potting mix and a little cow manure to give my seedlings a boost. An occasional water and let the sun do the rest!
