Like all nightshades, peppers love the heat. They thrive in daytime temps between 70 and 80 degrees. At night, they don’t like to get much cooler.
If you plan to plant more than one pepper in each pot–something that is possible with non-bushy varieties of bell peppers and others–pick a pot with at least a foot in diameter.
The soil inside pots is subject to a much different environment than the soil in a garden bed. There are no earthworms or other bugs available to aerate it.
Most pepper varieties take some time to mature, and all prefer to produce during the hottest months of the year.
