The space between the holes should be at least 30 inches. Then, pinch off the leaves along the tomato start’s stem, leaving the top 1 to 2 sets of leaves.

Spread a 3- to 6-inch layer of compost over the planting site. Mix the compost into the soil, and rototill it to a depth of 12 inches. Smooth the soil with a rake.  Then, spread the seedling roots outward and place it into the hole. Re-fill the hole with soil and water the plant thoroughly.
