What Temp Should You Cover Tomato Plants?

Tomatoes are a popular and delicious addition to gardens and homegrown produce. However, they are sensitive to temperature changes and can be damaged by frost or extreme heat. To keep your tomato plants healthy and thriving, it’s important to know what temperature you should cover them. In this article, we will discuss the optimal temperature range for tomato plants and the best ways to protect them from extreme temperatures.

The Optimal Temperature Range for Tomato Plants

Tomato plants prefer moderate temperatures between 70-80°F during the day and 60-70°F at night. Temperatures that are too high or too low can stunt growth, reduce yields, and damage the fruit. During the day, temperatures above 85°F can cause the flowers to drop and prevent fruit from setting. Nighttime temperatures below 50°F can also lead to flower drop and fruit damage.

Protecting Tomato Plants from Frost

Frost can cause severe damage to tomato plants and should be avoided at all costs. Tomatoes are particularly vulnerable to frost as their leaves and stems are delicate and easily damaged by ice crystals. The best way to protect tomato plants from frost is to cover them with a protective material such as burlap, blankets, or frost cloth. Covering the plants before sunset can help trap warm air close to the ground and prevent frost from settling on the leaves and stems.

If you live in an area with frequent frost, consider planting tomatoes in containers that can be moved inside during cold nights. Alternatively, you can use a greenhouse or cold frame to provide a controlled environment for your tomato plants.

Protecting Tomato Plants from Extreme Heat

Tomato plants can also suffer from heat stress during hot summer months. High temperatures can cause the leaves to wilt, reduce yields, and damage the fruit. To protect tomato plants from extreme heat, provide shade during the hottest parts of the day by using shade cloth, umbrellas, or planting them near taller plants that can provide natural shade.

Watering regularly is also crucial during hot spells. Tomatoes need consistent moisture throughout the growing season to produce healthy fruits. Water deeply and frequently in the morning or evening to ensure the soil stays moist but not waterlogged.

Conclusion

Tomatoes are a sensitive plant that requires optimal growing conditions to produce healthy and tasty fruits. Temperature fluctuations can cause damage to tomato plants and limit their growth potential. By understanding the optimal temperature range for tomato plants and using protective measures, you can ensure your tomato plants thrive and produce abundant fruits.
