Microgreens are fast-growing and nutritious sprouts (like the sprouts that are often used as agarnish in restaurants and cafes). These are sown thickly in containers and looked after as you would any seeds you sow. They are harvested when they are about 3-5cm high before the sprouts start to grow their mature leaves. Use them in salads or sandwiches.
Make your own liquid fertilisers using manure, seaweed, compost or weeds
