What to Put Over Tomato Plants for Frost

Tomato plants are very sensitive to frost, and protecting them from freezing temperatures is essential for a healthy harvest. Covering the plants is the most effective way to protect them, but there are many options for what to use as a cover. In this article, we'll explore some of the best choices for what to put over tomato plants for frost.

Frost Cloth

Frost cloth, also known as row cover or garden fabric, is a lightweight and breathable material that provides excellent protection for tomato plants. It can be draped directly over the plants or supported by stakes or hoops to create a tent-like structure. Frost cloth allows air and water through while protecting from frost, making it an excellent choice for gardeners in regions with fluctuating temperatures.

Plastic Sheeting

Plastic sheeting is an inexpensive option for protecting tomato plants from frost, but it has its drawbacks. While it does provide a barrier against cold air, it also traps moisture, which can lead to mold and disease. Additionally, plastic sheeting is not breathable, so it must be removed during the day to allow the plants to receive sunlight and ventilation.

Blankets or Tarps

If you're caught in a sudden frost and don't have any frost cloth or plastic sheeting on hand, you can use blankets or tarps to cover your tomato plants. While they're not specifically designed for garden use, blankets and tarps can provide temporary protection from frost. However, they are not as effective as more specialized materials and can be heavy and cumbersome to work with.

Greenhouse or Cold Frame

A greenhouse or cold frame is the ideal solution for protecting tomato plants from frost, but it may not be feasible for all gardeners. If you have a greenhouse or cold frame, you can easily maintain a more consistent temperature and protect your plants from the elements. This option is particularly useful for gardeners in areas with long stretches of cold weather.

Final Thoughts

Protecting your tomato plants from frost is an important part of a successful harvest. While there are many options for what to put over tomato plants for frost, frost cloth is the most effective and efficient choice for most gardeners. However, if you don't have frost cloth on hand, blankets or tarps can be used as a temporary solution while you source a more specialized material. Whatever you choose, be sure to cover your tomato plants before temperatures fall below freezing to ensure a healthy and bountiful harvest.
