Thin the seedlings when they are 3 inches tall, leaving four inches of space between each one.
Apply 3 inches of organic mulch after thinning. Keep the mulch at least three inches from the plants.
Remove weeds that develop around the plants by hand. Eliminate weeds from between the rows, using a garden hoe.
Apply 10-10-10 fertilizer, in the amount indicated on the package, alongside the seedlings when they reach a height of 6 inches. Keep the granules four to six inches from the plants, and water deeply after the application.
