After the last frost set your tomato plants outside to start adapting to the environment.
Your plants should be about ten inches high without flowers or fruit.
Prepare a hole about eight inches deep.
Put a banana peel in the bottom of the hole and cover it with a little bit of compost or potting soil.
Strip off the lower leaves and put the plant into the hole.
Fill in with soil that has been amended with compost.
Fertilize with Vitamin B
Roots will grow from the entire buried stem.
