It's time to start off some types of vegetable seeds indoors or in a greenhouse. If you don't have a greenhouse (I don't and will never have the room either) this is most easily done on a windowsill in a propagator or in flowerpots inside a sealed plastic bag so that each plant has its own mini-greenhouse. It's a good idea to blow into the bag befote tying the top to give the seedlings headroom. This week get a head start by sowing chillies, sweet peppers, courgettes, tomatoes, cucumbers, globe artichokes, sweetcorn, pumpkins, marrows and melons. I have also bought some Jerusalem Artichoke tubers and will be planting the them in a large container as in a bed or border (I grow my veg and flowers cheek by jowl because of limited space) they can spread where you don't want them and be a bugger to eradicate.
