Crisp spring vegetables and herbs can be planted in your bed from March: radishes, rocket, and leaf lettuce are all suitable for planting in the spring and will be ready to harvest by summer. Spinach can also be planted now.
A little later, around the end of April, you can plant spring onions, other onions and leeks.
If you leave a little extra space, you can also plant peppers and chillies from May. If you build multiple raised beds, you might include courgettes or summer squash, which are a good growing choice but need a lot of space: we recommend leaving 1 metre in all directions between plants. If you plan to grow tomatoes in your raised bed, compact bush varieties are ideal.
