Japanese Knotweed update 14 May 2017

The big clump

 Normally by mid May, Japanese Knotweed is much greener and much bushier than this, so unfortunately, the Knotweed in the chosen location has not grown as dense and prolific as I was expecting. The young shoots below have distinct yellow stripes and the leaves are limp. The native vegetation growing alongside looks healthy, so it is not likely that it has been affected by any chemical treatment.

Limp and yellow leaves of young shoot

 Will return here once more, then will wait for several weeks to see if the Knotweed has bushed out. It is probable that a tree canopy above is the cause of the weaker than expected growth.
