I have planted most of the tomatoes. Part of me can't believe it is already time and the other part of me is chomping at the bit.
To plant my tomatoes I dig really deep holes, about 10-12 inches and then adjust based on the plant size. I like to bury most of my plant because it creates a better root system and then you are left with a short sturdy plant to grow in.
I amend the soil in the hole with eggshells, aspirin, bonemeal and tomato tone. This is a mix that I have picked up along the way. I do about a palmful of each except the aspirin, I use about 2 per plant. Put a little soil above the amendments, plant the tomato, fill in with dirt, and water.
