March they say is when the growing season really starts to take off, definitely on a windowsill, in the greenhouse or grow tunnel. Outside is possible too, but as we all know it becomes dependent on the weather. Ideally the soil temperature should be over 10 degrees Celsius. March is also the time when the weeds start to spring up, so the hoe becomes an everyday tool in use. Also slugs & snails seem to emerge. Controlling them early in the season can have a big impact later on by disrupting the breeding numbers.
What you could grow in March in the greenhouse, broad beans, Brussels sprouts, Leeks, broccoli, salad leaves, radish, lettuce, onions, peas, globe artichokes, spring onions, summer cabbage, celery, early cauliflowers, cress. Also start off at home in the house, tomatoes, cucumbers & peppers.

Remember to always read your instructions on seed packets.
