With short daylight hours and not much happening in the garden outside why not cheer up a kitchen window ledge with a pretty pot of cress, the new micro salad. It is super speedy to germinate and for under 2 pounds, a packet of seeds will last you through the winter if you make a succession of small sowings. Scatter a few seeds on top of damp multi purpose compost in a small pot, place in a light, warm environment and soon you will see the seeds literally growing. Keep a small pair of scissors handy for harvesting, water regularly but not too much and in under 10 days you will be picking tasty leaves. I sow cress every 2/3 weeks throughout the winter months. Try mustard leaves too, they will add a kick to your salad.
