The garden is frost free by June, which means it is safe to plant out all remaining veg. Plant out Peas, Beans of all types, salad crops, rocket, carrots, everything not yet planted out including the more tender of crops such as courgettes, squashes, cucumbers, French beans and Tomatoes. All types of beans can be planted out now and also seeded directly into the veg plot for later crops. Beans and Peas all have different growing requirements check out which you need before planting.
June is planting time. Plants which are seeded or planted together, will produce fruit together, i.e. all at the same time which will produce a glut. To avoid gluts it is better to sow and plant regularly, and easy to remember rule of thumb is to plant every fortnight. Keep sowing and planting each fortnight until late in the season, depending on the vegetable. Seed packets will give a guide for last planting dates but always adjust dates by your garden aspect. The South has a longer growing season than the North of England. Some veg grow more quickly and can be sown again late in the season, such as radish and lettuces others, for example squash need the whole season to come to fruit and are usually sown at the beginning of the year.
