Having a beautiful garden takes patience and a lot of time. Indeed, to constitute a natural and flowering garden is a considerable work. However, it should not become a nightmare if certain plants invade your land. It is therefore important to control and contain plants that may be “harmful” to others.
The barrier embedded in the ground
You are going to plant plants with tracer roots and you don’t want them to spread everywhere in your pretty garden? The root barrier is an ideal protection against invasive plants. Indeed, this barrier will prevent the roots from spreading out in your garden. For optimal efficiency, you must first dig your hole and put the protective cover around it. This will delimit the space of your plant and fight against the propagation of roots. Depending on the species of your plant you will need to install a thicker or thinner root barrier. You can find tarpaulins from 325g/m2 to more than 1900g/m2.
Commonly used for bamboo plantations, rhizome barriers work wonders for this type of plant. Known to be evasive, bamboo has very invasive roots and can harm the beauty of your garden if it is not framed.
Nevertheless, this protection is useless against plants with deep roots. Indeed, this protection has no effect against plants such as Japanese knotweed which can have roots up to more than 3m deep.
The sun barrier
As you know, all plants need light to flourish. A thick tarpaulin that deprives plants of light is therefore a good way to protect the soil from weeds or other plants. Be careful, do not put a geotextile tarpaulin, this type of “protection” lets a little light through. However if you wish, to preserve your ground of all harmful plants it is imperative to put a protection of impermeable quality with the sun.
After the tarpaulin has been installed on the ground, you will have to wait several months (from spring to autumn) for optimal efficiency.
Pruning your plants
You don’t want to sacrifice the natural beauty of your garden by inserting an unsightly black tarpaulin. Nothing simpler, a little elbow grease and a good pair of shears and you are off to prune your plant. The action of cutting will densify your plant and make it more resistant in the long term. Continuously cutting the regrowth will eventually discourage your plant from undermining its energy in its photosynthesis phase. Maintaining your plants regularly will ensure a clean and well structured garden.
All that remains is to choose a method and be patient.
