The volume of water required depends on the time of year and the weather. However, a rule of thumb is that the soil must always be sufficiently moist. On the other hand, you must not over-water BrazelBerry® plants. This is very important. A rough rule in summer is: water plants in beds two to three times per week, and pot plants every two days. Daily watering is necessary at the height of summer.
Tip: ideally, water with soft rainwater.
