Pricking out lettuce seedlings

In this activity we used dibblers to gently lift individual lettuce seedlings from seed trays. It was important to handle seedlings by their cotyledons and not by the stem. Each individual seedling was placed in a propagation mix consisting of 50% compost, 50% pasteurised sand, 250gm of dolomite, 250gm of crushed biopellets per 50L of mixture.
