Summer Vegetable Planting Guide

Spring and summer offer a myriad of delicious vegetables you can easily grow in your garden. We’ve put together a planting guide to help you with what to plant, when and where. You can sow your own seeds into seed trays indoors or directly into the garden, depending on the vegetable. As a rule of thumb, plant the seed as deep as the size of the seed, so a 1cm size seed should be planted 1cm deep. If you are planting tiny seeds such as lettuce or radish, just sprinkle the seeds in a line and cover lightly with Daltons Seed Raising Mix. Alternatively, you can purchase seedlings from your local gardening centre.
