Delighted to share my next feature on Richard Jackson's Garden website.
Japanese knotweed or Fallopia japonica is a very vigorous herbaceous perennial that spreads via deep rhizomes (underground stems). Its bamboo-like hallow canes can reach three metres high and grow 10cm a day in the summer, smothering surrounding plant growth.
If you've heard the horror stories about Japanese knotweed you might want to know how to identify it and whether it's really as bad as everyone makes out?
