Sowing time
It is time to think about sowing brassicas and even tomatoes in seed boxes. for later planting out. I have found this method very successful. Visit you local glazier and ask him to cut some pieces of glass the same size as a standard seed box. A counsel of perfection would be to get them framed, but you can do that later. Put in a cell divider (12 cells is ideal) into the seed box and fill with a good soil base seed compost such as John Innes Seed compost (available at Wilko stores and elsewhere.) Don't fill right to the top, but leave about an inch for the seeds to push up. Firm the compost gently and with small seeds, just put the seed on top of the compost - no need to bury. Place the glass on top and cover with a sheet of brown paper. The seeds should germinate within a few days - perhaps a week. As soon as they have germinated, remove the glass and paper and leave near window or in a green house and water regularly but gently with a spray, preferably with luke warm water.
