All you need is a suitable container, a packet of seeds for
'cut and grow again'' lettuce seeds, and a pack of suitable compost.
You can grow your salad leaves in flower pots, or even use the plastic containers that fruit is supplied in. Fill the container/pot with compost and sprinkle the seeds over the surface, cover to the depth suggested on the seed packet with more compost. Keep watering when needed.
When the leaves are a good size cut them to harvest them, being careful not to damage the roots by tugging at them. If harvested correctly the leaves will regrow once or twice to provide another salad leaf harvest. If you want a useful constant supply do not forget to plant another container of salad leaves every two weeks or so. This is a nice easy healthy way of adding fresh salad leaves to your diet/lunch box. You can cut just enough for a sandwich or salad and there is no waste. When the leaves have ceased to re-grow do not throw the compost into the rubbish bin. The compost will be good for your garden or compost heap. Enjoy growing,harvesting and eating your own grown salad leaves this summer.
