Can you grow tomatoes in cool weather?

Tomatoes need to be kept well above freezing to survive. There's no point trying to put them outside – or even into a greenhouse – until your last expected frost date has safely passed. Temperatures below 10ºC (50ºF) can result in slow growth and problems with flowering and fruiting.

What is the lowest temperature tomato plants can tolerate?

Low Temperatures

Although tomato plants can survive temperatures down to 33 degrees Fahrenheit, they show problems when temperatures drop below 50 degrees F, according to the U.S. Department of Agriculture Research Service.

Should I cover my tomatoes at 40 degrees?

Tomatoes thrive when they receive consistently warm temperatures, between 70°F to 85°F during the day and between 59°F to 68°F during the night. Now, since 40°F is way off the mark even for nighttime temperatures, covering the plants is an excellent idea to protect them from cold damage.

What temp will kill tomato plants?

Tomato plants will survive temperatures down to freezing, so a low temperature of 35 degrees will not kill them. Insulate the plant with sheets or cloches if frost threatens. To ensure plant safety, protect tomato plants any time a temperature of 35 degrees or below is expected.

Can tomatoes grow in 60 degree weather?

Tomatoes flower and set fruit best when the air and soil temperatures range between 60 and 70 F. ... Above 95 F, the flowers abort and will not produce fruit. Growers at either extreme can extend the tomatoes' temperature range by providing warmth and shelter in cool areas, or shade and air circulation in warm areas.

What is the best climate to grow tomatoes?

Tomatoes need consistent night temperatures between 55°F and 75°F to set fruit. (A few varieties will set fruit at lower or higher temperatures.)

Is morning or afternoon sun better for tomatoes?

For healthy growth, tomato plants require at least 8 hours of direct sunlight a day. However, the hours of sunlight do not need to be consecutive. This means that tomatoes can be grown successfully in both morning and afternoon sun as long as the number of hours adds up to 8 or more.

Can tomato plants get too much sun?

Tomato plants that receive too much sun and heat become stressed and fail to flower or drop the flowers and fruits. With proper care, when daytime temperatures drop below 95 degrees Fahrenheit, the plants will recover.

When should you cover tomatoes at night?

Although tomato plants start out pint-sized, by autumn they can be absolutely massive – especially if they are of the indeterminate variety! To keep your tomato plants productive for as long into autumn as possible, they will need to be covered up each evening when temperatures dip below 50°F (10°C).
