Japanese Knot Weed - specialist removal of this rampant disease!

Japanese knotweed is an invasive weed which must be dealt with professionally - and to very strict guidelines. We are fully proficient in this.
Despite the government's efforts to control weed legislation, this rampant weed has now integrated itself widely into the English landscape. Rooting to a depth of 5m plus, it sends up growing tips capable of pushing through tarmac or disabling drains, establishing itself on any type of soil and locality very easily. This weed is a serious problem and should be dealt with as a fundamental part of any landscape maintenance.
Being a licensed sprayer and horticultural specialist Garden-Scape is able to identify, eradicate and make good all occurrences of Japanese knotweed very effectively. And with associated earth-moving colleagues, able to dispose of contaminated soil to landfill site which are specifically licensed for this purpose.

Garden-Scape can offer the following options:

Option 1: Spraying the infestation. A highly effective and affordable option - although, this is not recommended if you plan to build on the area, as there is a risk of reoccurrence.
When treating large infestations of Japanese Knotweed in this manor it takes 3 years and therefore is not convenient for the developer. Also when not removing the soil from the site there is a danger that mature plants have set seeds on the top soil and this will go unnoticed. Just one small piece of stem no larger than a paper clip can grow back into a plant capable of penetrating the ground to a depth of 5 meters and with a spread of up to 7 meters in circumference. Spraying only option is suitable in large gardens, estate grounds, railway lines & road verges and land not intended for building or land not intended to bare vegetative growth such as car parks and foot paths.

Where there is a real danger that spraying may harm surrounding cultivated or native plants of value we would recommend direct injection of Japanese knot weed stems. Situations, such as native hedge rows and flower borders of parks benefit well from this method.
Option 2: Extraction of soil and spraying: This is our recommended route. We'll make a special area at the location called a 'bund' which is lined with a heavy gauge plastic membrane. This is where we will place the extracted soil which is contaminated with Japanese knotweed roots and seeds. Plants and roots can be stored away and treated three or four times a year with weed killer for at least three years. After this period, the site will be inspected for the presence of Japanese knotweed and the all clear will be issued, the infestation will have been removed from the soil, which can now be reused.
