Grow tomatoes all winter - just take a clipping of your favorite tomato plant. Continue the growing season by growing tomatoes indoors. Then in the spring, take a cutting to grow another tomato plant outdoors. Use an indeterminate plant, and you can continue on throughout the seasons. You can grow a tomato clone from a sucker or other cutting. This video is an update starting after the clipping has soaked in water for two weeks. Start with an indeterminate tomato plant. Clip the end of an actively growing branch or sucker. Make sure there are only a few leaves and no buds. Remove all lower branches and place the branch in a glass of water making sure to cover all the parts of the branch that were cut. Change the water every few days. In one to two weeks, you should have a good number of roots developing. Plant this is garden soil or potting soil. Keep moist for at least two weeks. You can then plant this for indoor tomatoes. Or slowly harden off the plant by exposing it to wind and more and more sun. There is nothing better than a fresh tomato.
