This biodiversity roof is very easy to maintain.
Additional water and nutrients are not needed for this green roof, as this would otherwise disturb the natural balance.
Only in very extreme periods can you water the roof once a week.
We also recommend mowing the roof in September.
Please take into account the presence of insects.
We therefore recommend that you mow in phases.
