Growing conditions across the UK in March can vary dramatically. By mid-March your soil might be starting to warm up, or it could still be too cold to sow. It is always worth checking your soil temperature with a soil thermometer before you start to plant seedlings directly into the soil.

There are still a few seed varieties you will need to sow inside. If you have a propagator or greenhouse, this is ideal. But if not, then a warm and bright windowsill works well too.
