Installing your landscape fabric properly ensures real, long term weed proofing.
When installed properly, your weed suppressant can act as a long term barrier against tough perennial weeds such as couch grass, bindweed, horsetail and nettles.
While it doesn't take a master's degree in weed proofing to install, there are several key factors to bear in mind when installing your ground cover membrane. These are just three key points to think about.
Overlap and fold over at the edges to prevent fraying.
Too often we see landscape fabric cut with edges exposed, resulting in the woven fabric fraying and decaying much faster than it should. When left exposed, it only takes a few scuffs or windy days to untangle the weaves in your fabric.
A long term solution is to fold over the edge and pin down the membrane securely. This ensures the exposed edge of the weed proof fabric is a solid, woven end with no loose edges for fraying.
Ensure there are no air pockets under the fabric
Air pockets give room for weeds to grow into, allowing prolific growers such as couch grass and horsetail to grow into with momentum. This is one of the main reasons for thick polypropylene landscape fabrics failing to keep weeds down.
Another by-product of allowing air pockets is increased slug and snail population. These air pockets provide warm, damp conditions that are perfect for slugs and snails to breed and hide. Removing these air pockets deprives them of breeding sites, thus removing the need for slug and snail control.
Selectively plant using the smallest hole necessary and cover up to the stem.
Making sure that only your selected plants grow is important in ensuring healthy growth in weed free conditions. However, there are many weeds that propagate by growing their root systems to find exposed sites where they can throw shoots up. Always ensure that any soil that isn't holding a stem is covered with mulch or fabric. This stops weeds growing up your selected plants and improves the health of the plant.
