Ideal Temperatures for Thriving Microgreens Outdoors

Microgreens are young vegetable greens that are harvested just after the cotyledon leaves have developed. They are a nutrient-rich food source that can be easily grown at home. When growing microgreens outdoors, it is important to consider the temperature requirements of the specific type of microgreen you are growing. Most microgreens prefer to grow in cool weather, with temperatures between 60-70F (15-21C). However, some microgreens, such as arugula and mustard, can tolerate cooler temperatures, while others, such as basil and cilantro, prefer warmer temperatures.

It is important to protect microgreens from extreme temperatures, such as frost or heat waves. If the temperature drops below 40F (4C), the microgreens may be damaged or killed. If the temperature rises above 85F (29C), the microgreens may bolt, which means they will start to produce flowers and seeds. Bolting makes the microgreens bitter and less nutritious.

By understanding the temperature requirements of the specific type of microgreen you are growing, you can ensure that you are providing the best possible conditions for growth. This will help you to produce a bountiful harvest of nutrient-rich microgreens that you can enjoy all season long.
