Tip of the week: Create a water buffer

Trees have a positive effect on our green living environment and they improve biodiversity in urban areas. They also serve as filters for urban air pollution and particulate matter. They cool the air by 2 to as much as 8 degrees Celsius and combat climate change by absorbing CO₂. On top of that, the presence of nearby greenery increases residential property values by 4 to no less than 15%.   

Trees make a ‘green contribution’ to our living environment, but the climate is changing faster than trees can counter and this has negative effects on their water management. A gradual flow of water is the one essential thing for optimal healthy tree growth. Urban areas are increasingly subject to a disrupted water balance: flooding due to intense precipitation or water shortages after sustained periods of drought. As a consequence, trees have a hard time staying upright.

A large part of rainwater evaporates and the remainder often ends up in the sewers, because soil and hard surfaces cannot absorb a large quantity of water at once. Slow, steady moisturising of the soil around a tree ensures that the tree has the opportunity to absorb water and extract the nutrients that it carries when needed. With the RootBarrier® WaterBag you can create a water buffer.The WaterBag has a maximum capacity of ca. 75 litres; it releases a trickle of water that lasts ca. 6 to 10 hours. Moreover, multiple WaterBags may be zipped together to increase the capacity.
