Apply a balanced, water-soluble fertilizer mixed to half its recommended strength with every other watering after the seedlings produce their first true leaves – the first pair of leaves after the initial seed leaves that emerge at germination. Water enough to keep the potting soil evenly moist, never letting it dry out or become waterlogged.
Transplant the seedlings to separate 1-gallon containers filled with standard potting soil when they have at least three sets of leaves. Allow them to grow in a sheltered area for several weeks before transitioning them to their permanent outdoor location when all danger of frost has passed
