How to extend raspberry growth until autumn?

2. Water raspberries regularly, especially in hot weather. Raspberries need moisture to grow and develop well. Raspberries should be watered daily or every other day during fruiting. It is better to water less often, but more. It is recommended to soak the soil to a depth of 30 centimeters. It is impossible for a crust to form on the surface of the earth, which indicates that the earth is too dry. The guideline for watering or not watering raspberries is the ground itself: if it crumbles when squeezed in your hand, then watering is necessary.
