Adam sows agretti

In this clip, Adam demonstrates how to sow agretti. This vegetable is very popular in Italy, but seeds can be tricky to germinate. His first batch of seeds only had a 40 per cent germination rate, so he changes the compost to a more open mix of peat-free compost, horticultural sand and perlite with the aim of improving germination rates.

Adam shows how to sow kohlrabi, an unusual-looking member of the cabbage family. Easier to grow than some other brassicas, such as swedes, it is ready to be harvested from around eight weeks. Adam has chosen a purple variety called 'Azure Star', and he suggests some of the different ways this delicious vegetable can be cooked.
