People always underestimate the difference in the taste of home grown lettuce. It really does taste so much better than shop bought. I like to sow a variety of different colours and shapes, that way the salad looks much more interesting.

You can so directly into the soil, but I prefer to sow mine in a seed tray. Here’s how I sow mine.
