The United States Department of Agriculture (USDA) reports that tomato plants can withstand temperatures as low as 33 degrees Fahrenheit, but they begin to experience issues when the temperature drops below 50 degrees Fahrenheit. The Agricultural Research Service of the Department of Agriculture.
- The capacity of tomato plants to convert sunlight into sugars through the process of photosynthesis is hindered when nighttime temperatures drop below a certain threshold.
- The generation of pollen is inhibited when temperatures are low, which can lead to a reduction in fruit output or possibly the malformation of fruit.
When overnight temperatures dip below 60 degrees Fahrenheit, the blossom end of the fruit can develop a condition known as cat-facing, which consists of puckers, scars, and fissures.
Is 38 degrees too cold for tomatoes?

After the date of the last frost and the beginning of spring is the ideal time for me to cultivate tomato plants. However, every once in a while, they are visited by an unforeseen frost.
Because of this, it is essential to have a good understanding of how much cold the tomato plants can withstand as well as how to protect them. How cold must it get before tomato plants die off? Temperatures lower than 50 degrees Fahrenheit are fatal to tomato plants. The tomato seeds won’t germinate, the young tomato plants won’t develop properly, and the mature tomato plants won’t produce any fruit even though they’ve reached full maturity.
Frost will form at a temperature lower than 32 degrees Fahrenheit, which will cause the tomato plants and their fruits to perish. When given the appropriate quantity of sunlight and heat, a tomato plant will develop to its full potential. You have to be aware of when the best time is to grow them.
What is the lowest temperature bell peppers can tolerate?
If you are anything like me (and the majority of other gardeners! ), you want to get a head start on planting your pepper plants as soon as you possibly can. At the conclusion of the season, you should extend the time you spend cultivating them for as long as you possibly can.
- However, the weather does not always cooperate, and frosts that occur late in the spring or early in the fall might cause your plants to get damaged or even die.
- Therefore, what is the absolute minimum temperature that pepper plants can withstand? Frost, which may kill pepper plants if it reaches 32 degrees Fahrenheit or below, can occur when the temperature drops below that.
When the temperature drops below 55 degrees, it will hinder the growth of seedling pepper plants and impede the growth of adult pepper plants. It is important to ensure that the soil temperature is at least 75 degrees Fahrenheit while growing peppers from seed.
- Your pepper plants may be protected from the cold and frost in a number of different methods, which is fortunate.
- Your harvest may be prolonged by a few weeks if you took a few of these precautions at the beginning and the end of the growing season.
- In this post, we’ll take a look at some of the ways to protect your peppers from cold, offered in approximately chronological order.
(While you’re at it, you can check out a variety of materials on this page pertaining to cold protection.) Let’s get started.
Is it too early to put tomato plants outside?
When to plant tomatoes outside It is crucial to know when to put tomatoes outside if they were seeded indoors first. When should tomatoes be planted outside? The response is that the plants should be transplanted outside once the danger of frost has gone and the soil has warmed up.
- When this should happen will depend on the growth zone you are in as well as the weather conditions.
- Tomatoes can benefit from companion planting with other plants that can increase their yield and ward off pests.
- Tomatoes are typically transplanted outside anywhere from 0 to 4 weeks after the date when the last frost is expected to occur in your region.
When the overnight temperature lows are at or above 50 degrees Fahrenheit (10 degrees Celsius), the majority of tomato plants are planted outside. According to gardening blogger Mary Jane Duford, this happens often a few weeks after the day that the area saw its last frost.
- Tomato seedlings develop extremely slowly at temperatures below 50 degrees Fahrenheit (10 degrees Celsius), and they may be harmed at temperatures below 43 degrees Fahrenheit (6 degrees Celsius).
- The size of your plants will also determine whether or not they are ready to be moved outside.
- Annie Singer recommends that in order for immature tomato plants to be planted outside, they should be around 9 to 12 inches tall (23 to 30 cm), and they will need to go through a phase in which they are “hardened off.” She advises: “Before planting them directly in the dirt, be sure to gradually expose them to the outer environment over the period of one to two weeks to allow them to adjust to direct sunshine, wind, and temperature variations.” It is important to keep in mind that after the tomato plants have reached a certain size, it is time to begin the work of trimming indeterminate tomato varieties, which include cordon and vine types.
Keep an eye out for any symptoms of illness so that you may treat outdoor-grown tomatoes for tomato blight if required. However, you should be aware that the disease could also affect plants that have been cultivated in greenhouses. (Credit for the image goes to Getty Images)
What nighttime temperatures can tomatoes tolerate?
It is unusual to discover a vegetable garden that does not have at least some tomato plants. Tomatoes require abundant light, fertile soil, and warm temperatures in order to flourish as plants that produce an abundance of tomatoes that can be picked and eaten.
- The question is, then, what kind of weather conditions produce the best tomatoes.
- Is it too chilly for tomatoes to be outside when it’s 40 degrees at night? Tomatoes cannot tolerate temperatures below 40 degrees Fahrenheit at night, which increases the risk of crop failure.
- Tomatoes thrive in environments with daily temperatures ranging from 70 to 85 degrees Fahrenheit and nighttime temperatures ranging from 59 to 68 degrees Fahrenheit.
Temperatures at night that are too low (below 55 degrees) can stifle the production of pollen and retard the maturation of fruit. Gardeners may use the optimal temperature ranges for daytime and nighttime temperature to assist them estimate when the best time will be to sow seeds and set out transplants in their particular location.
