How to Sow
Whether you are growing cress in containers or soil, sow it where it is to grow. You can start harvesting really early, so theres not much point in transplanting it. Give it rich soil and plenty of moisture. Sow every 10 days for a constant supply.
How to Harvest
As soon as you have leaves on your cress seedlings, you can start using them as a source of microgreens. Pinch or trim out the tips, leaving a piece of stem and a pair of leaves for resprouting. If you use them as microgreens, they may not resprout.
