Rooting Tomato Cuttings For Cloning
Rooting tomato cuttings is easy. Take a new growth or a sucker cutting a few inches long. Put the cutting in an inch or two of water.
Within a week or two, you should see roots start to grow along the stem.
When you see plenty of roots growing, remove the cutting from the water and put in a soft seedling mix, burying it about half way.
