RAISING SEEDS
What’s the best medium to raise seeds in?
Seed-raising mix is a bit of a misnomer. While it’s light and friable and easy for germinating seeds to push through, it doesn’t contain the nutrients required to grow healthy seedlings. A seed holds enough stored energy to be able to germinate, but it will quickly need additional nutrients to develop into a strong seedling.
A homemade growing medium of finely sieved compost (or a good-quality potting mix) mixed with a handful of worm castings will provide a nutritious media to plant your seeds into. If you’ve already purchased a bag of seed- raising mix, use it to cover your seeds after planting.
