The AquaMax tree irrigation barrier is used to avoid water loss and dry soil that can impair growth especially of young trees. 10 cm of the barrier are laid underground, the remaining 20 cm form an irrigation dyke overground. The over-lapping ends are then simply fixed with the coupling (item no. 44 01 83) or can be nailed to a tree stake. This provides a stable construction keeping the rootball watered effectively. Example: 2.5 m equals 80 cm diameter = approx. 100 ltr filling capacity.
