Asparagus
Although it has only a short season, asparagus has to be one of the tastiest veg you can grow yourself. It needs space in full sun as well as shelter from wind. If your soil is very wet or heavy, grow it in a raised bed. The crowns are best planted between March and May. Dig in lots of well-rotted manure or compost and make a trench about 30cm wide and 20cm deep, then make a 10cm high ridge along the length of the trench. Sit the crowns on top of the ridge with the roots hanging down, then backfill. Cut only a few spears from April to June (but not in the first year, to allow the plant to build itself up), and mulch well each autumn
