If I harvest bell pepper, will it grow back? (I control the temperature in my small greenhouse)

Will the pepper grow back? Not exactly. However, after you harvest the pepper the plant likely will produce more flowers, which can be pollinated and grow into more peppers.

No, it doesn't. If the ground is frozen, you're a long way until the last frost. Frost is an icy substance that forms on the ground, plants, car windshields, and things. It tends to form in the early ...
