Sow and plant
Sow heirloom pumpkins and zucchini. The ribbed zucchini Costata Romanesco is an Italian classic with firm, flavoursome flesh. • Sow a new row of dwarf beans every fortnight for a constant supply. • Plant lettuces for summer. Crispheads like Iceberg don’t like the heat, whereas Cos and Buttercrunch varieties are summer stalwarts. • Sow quick crops of baby kale, microgreens, radishes and rocket for salads.
