Take a pot, new or otherwise. Fill it most of the way with good quality organic potting mix or rich, healthy soil from your garden (worms optional). Sprinkle with fertiliser - Rooster Booster, Blood and Bone, Compost, Worm Castings. Add seedlings, purchased or home grown. Top up with soil or potting mix if needed. Water with liquid fertiliser or worm wee. Put in a sunny spot and water each day. Pick as desired. Enjoy on demand.
