If you live in a hot climate, you might need to shade your container plants during the heat of the afternoon, so they don’t overheat. It may also help not to use metal or darker colored containers, because they can become very hot and cook your plant’s roots. A shade cloth can help with this on very dark pots. On the other hand, many vegetables do not like cold soil. So, if you live in a cool climate, bring your containers in at night until you know the overnight temperature will be warm from night to night.
