Plastic Tomato Tee Pees
Tomato TeePees are a modern variation of the Tomato cage, they are excellent for growing determinate tomatoes, they help provide heat during cooler weather. The tomato teepee wraps around the plants, supporting them off the ground. They also contain water cells or chambers that you fill yourself. The water will heat up during the day, keeping the plants warm during cool nights or in early and late season temperatures.
This warming action promotes quicker growth and better yields. Some manufacturers claim you can plant tomatoes outdoors up to 6 weeks earlier, personally - I wouldn't go that early - I've been doing 3-4 weeks . You can also extend your growing season several weeks further into the Autumn . They can be used on Tomatoes, Eggplants and Pepper - they would probably work on Okra and a few other plants as well, but I haven't experimented yet.
Red Tomato Tee Pees are said to work best. As is the case with Red Mulch , the red plastic reflects red light wavelengths into the tomato plants. This triggers the release of natural plant proteins that stimulate rapid growth and development.
