Seminar focuses on Japanese Knotweed
Complete Weed Control franchisees recently held a one day seminar to discuss the control and eradication of Japanese Knotweed.
Industrial estates, building sites, gardens, river banks, roadside verges, cemeteries, schools and hospitals are just a few of the common areas affected, but many more obscure sites cropped up during the course of the day's discussion; on roofs, growing down into a boiler house, pushing through tarmac and concrete, even growing in the front room of a house! This diverse range of sites raised the question of how best to treat it - manual and chemical control being the two main options. Manual is the preferred method if eradication needs to be immediate, chemical being the choice if more time is available. But then, if chemical is the chosen method, it needs to be ascertained which chemical can be used. In the many situations where the weed grows the following questions need to be answered: Is it close to water? Are there other trees and shrubs in the vicinity? Is the soil to be used for other purposes? Given the answers to these questions, the resulting choice of chemical can then be very limited.
During the day, many of these questions were asked and answered, as there was invariably someone in the room who had, at some time, encountered and solved the problem. A manual on Japanese Knotweed control is to be produced as a result of the day's discussion, to ensure that the wealth of experience the franchisees have collectively gained can be shared throughout the Complete Weed Control network.
Richard Minton, Managing Director, commented: "Japanese Knotweed is a major problem and its control and eradication needs to be taken very seriously. Our company has been established for over 30 years and during that time we have had to deal with this invasive weed in every imaginable situation. We've become increasingly frustrated by the vast number of new companies emerging as so-called 'Japanese Knotweed experts', claiming to be able to totally eradicate the problem within very short timescales and with very little understanding of the virulence of the rhizome, which has been proven to still be viable after over 10 years of burial. Experience counts for a great deal when dealing with a plant that can regenerate from as little as four grammes of root mass so it makes sense to use a company with a successful track record of dealing with invasive weeds."
