Suppose you have plenty of decent gardening and realize that the weather is threatening with an early frost you have to protect it. Tomatoes and peppers are some of the crops that do not do well in the winter season. You have to harvest them before the frost falls and try to ripen them indoors.
According to the USDA Research Service, tomatoes show problems when temperatures drop below 50 degrees Fahrenheit. Cool nighttime temperatures interfere with the tomato’s ability to convert the sunlight into sugars via a process known as photosynthesis.
Generally, tomatoes require a favorable temperature between 15 degrees to 32 degrees Centigrade to survive. However, there are specific tomato varieties purposely bred for cooler climates with the ability to tolerate temperatures below 55 degrees Fahrenheit.
Temperatures that rise above 27 degrees centigrade, cause both tomatoes and peppers to suffer from too much heat. When they hit 32 degrees centigrade, the fruits will fail to set, and you will lose productivity on your plants.
