Basil Cold Hardiness The cold tolerance of basil begins to suffer when the mercury drops into the 40’s (F.) but really affects the plant at 32 degrees F. (0 C.). The herb may not die, but basil cold damage will be in evidence.
What outside temperature is too cold for basil?
Basil is the most healthy and productive at temperatures of 80 to 90 degrees F (27 to 32 degrees C). Chilly weather below 50 degrees F (10 degrees C) will begin to stunt the health of your basil. Once temperatures hit freezing (32 degrees F or 0 degrees C), your basil isn’t likely to survive for long.
What temperature should you bring basil inside?
As for temperature, many professional gardeners have concluded that the optimal temperature range for basil is around 72.5°–82.4°F (24°–28°C). At this temperature, you can harvest basil in bulk up to 5 times each season, and if you’re growing it year-round, you’ll be harvesting it numerous times.
How cold can basil get at night?
Staying Warm Basil grows best when daytime temperatures are consistently above 70 degrees Fahrenheit and night temperatures stay about 50 F, but it can survive and tolerate lower temperatures if there is no frost.
What temperature kills basil?
Basil plants are sensitive to frost, and any prolonged exposure to subfreezing temperature can kill the plant. But even temperatures below 50 degrees Fahrenheit can stunt the plant’s growth and might damage leaves.
What is the lowest temperature that basil will tolerate?
The cold tolerance of basil begins to suffer when the mercury drops into the 40’s (F.) but really affects the plant at 32 degrees F. (0 C.). The herb may not die, but basil cold damage will be in evidence.
What temperature can Peppers tolerate?
Most pepper plants can only tolerate temperatures down to 32 degrees Fahrenheit (0 degrees Celsius) before they succumb to frost. Even at more mild temperatures of 55 degrees Fahrenheit (13 degrees Celsius), pepper plants will show slower growth. As such, it is important to keep them warm at all times.
Is 100 degrees too hot for basil?
A study conducted in 2014 confirmed the effect of temperature on herb growth. For example, Basil will grow best when the soil temperature is at least 70°F (21°C). However, even at just 50°F (10°C) the Basil plant can be damaged by the cold and it’s leaves may blacken.
Does basil need direct sunlight?
Basil grows best with at least 6 to 8 hours of sunlight each day. Part of knowing how to care for basil is watching the sun patterns in the location you are growing this aromatic herb. With proper sunlight, your plant will be big and beautiful for several months out of the year.

Will basil come back after frost?
Also known as common or sweet basil, basil (U.S. Department of Agriculture plant hardiness zones 2 through 11 for outdoor gardens) is a true annual, which means it needs to be replanted each season. In most circumstances, it does not grow back after a year. Basil plants are sensitive to cold weather and frost.
How do you keep basil alive in the winter?
Wash the leaves and dry them with a paper towel. Then gather them in bunches and wrap the stems with a twist tie. Hang them upside down for a week or two and then break the leaves off the stems into an airtight container and you will have dried basil for the winter. Basil lasts this way for about a year.
How do you prepare basil for winter?
You can freeze entire leaves in small batches in small plastic bags or chop them and place them in an ice cube tray with a bit of water. Or, mix the chopped basil with a bit of olive oil and then freeze in ice cube trays.
Does basil like coffee grounds?
Coffee grounds do have a place in the growth of basil. You just have to be careful when you use it. We know that basil likes soil that is neutral to slightly acidic. It’s best to use compost that has coffee grounds in it rather than incorporate them directly into the soil.
At what temperature does basil turn black?
Basil plants can tolerate temperatures down to 50 degrees Fahrenheit (10 degrees Celsius). Basil is frost sensitive, so temperatures of 32 degrees Fahrenheit (0 degrees Celsius) or below will damage the plant. Any temperature below 50 degrees Fahrenheit can harm the plant or turn the leaves black.
Will basil grow back after cutting?
When you clip basil stems back to a fresh set of leaves, you force those leaves to grow, doubling the basil produced on that stem. And as those stems grow, you can pinch them back and double their production – it’s exponential! To remove flowers. Eventually most basil plants produce flowers.
What temperature is too cold for parsley?
It can tolerate temperatures as low as 20 degrees Fahrenheit, making it winter hardy in USDA zone 9 and above. Parsley dislikes humid weather and may die if temperatures rise above 90 degrees Fahrenheit.
What temperature is too cold for Rosemary?
Temperature: While rosemary survives below 30 degrees outside, inside keep the temperature in the 55 to 80 degree range. About 60 to 65 degrees is best. Air circulation: While not something usually mentioned, air circulation is important. Stagnant air allows mold and mildew spores to settle on plant leaves.

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.
What is the lowest temperature cucumbers can tolerate?
Any temperature below 50 degrees Fahrenheit (10 degrees Celsius) will result in slower growth of cucumber plants, and will eventually damage them. Cucumber seeds will not germinate (sprout) in soil colder than 60 degrees Fahrenheit (15.6 degrees Celsius).
