This is one of the busiest months in the vegetable garden with a flurry of sowing. I tend to sow most things in seed trays or modules initially, but the soil should be warm enough now to direct-sow most hardy vegetable varieties, including beetroot, chard, carrots and salad crops, straight into the ground. If doing this, use a traditional garden line to create drills and follow the spacing guidelines on each seed packet. Tender crops can also be sown under cover, in modular seed trays (tomatoes, sweet peppers and chillies) or 6-7cm pots (courgettes and squash). Pot these on as they get larger, or plant outside once the weather is warmer towards the end of May.
