Using seed can be an easy and cheap way to grow your own flowers and veg. If you are growing vegetables from seed you can pick varieties you like and also get a head start on the growing season, by early sowing such as cucumbers, courgettes and other vegetables in February.
To germinate and grow well, seeds need a controlled environment with as much light as possible. The light is as important as warmth /being frost free which is why sowing early in the year is more difficult when light levels are low. If you sow veg in February/March, you will also need somewhere frost free and warm for the seeds to grow and unheated greenhouse is likely to be too cold at this time of year. It is a balance; sow too early and the seedlings may struggle and be leggy, too late with some crops such as sweetcorn and tomatoes you may struggle to get a decent crop before the Autumn arrives if we have a bad summer or you garden in an exposed area.
