Everything you need to know about Japanese knotweed dormancy

Plant dormancy is when a plant slows down its activity in response to tough conditions. This helps it save energy and survive challenges like cold weather or lack of water. Different types of dormancy exist, like winter dormancy when trees lose leaves, and summer dormancy when plants in dry areas slow down.
