Earth up potatoes, keep drawing the soil up to a ridge every time they grow six inches, this will prevent sunlight getting to the tubers which will turn them green and make them poisonous. It will also increase the yield. Do this every two to three weeks, depending on how fast your potatoes are growing.
Broad bean tips can now be pinched out to prevent encouraging blackfly – be sure to provide adequate support now ready for when they produce pods. You can buy ready made support systems or make your own from garden canes and string. Peas will also now need supporting.
Now is the time to plant runner beans, they’re very easy to plant in seed trays and grow really quickly in the warm soil. Once again be sure to put supports in ready for them as they quickly climb and produce an abundance of delicious beans that are so much tastier than the ones you buy in the supermarket.
If you haven't already, then conditions look good to sow the seeds of beetroot, parsnips, turnips, peas, onions, mangetout and broad bean. Mixed salad, lettuce, watercress and rocket can be sown every two weeks; don’t sow it all at once or you will have so much salad that you won’t know what do with it.
Marrow, courgettes and squash seeds can be planted toward the end of this month.
