The growing medium within the Honeycomb blocks should consist of a
free-draining topsoil / compost mixture. Fertilizers should be used
with caution as they may affect the integrity of the concrete.
In addition the growth pockets should allow for free drainage of moisture
in order to prevent root saturation.
Regular watering is essential. For specific plant varieties, water
requirements can be obtained through your local nursery. Excessive or
continual watering should be avoided as this may lead to stability problems
and possible wall failure.
The planting of vegetation should take place as soon as possible after
the construction of the wall. A vegetation plan should ideally form
part of the contract but for smaller projects where professional advice
is too costly, the wall should be planted with hardy evergreen creeping
plants such as ivy.
Single species vegetation should be avoided as variety adds texture
to the wall and reduces the risk of total vegetation failure.
An abridged list of common recommended species for planting in the
Honeycomb Retaining walls appears below.
