Blackberry, ragwort and Bridal Creeper, attacked with sprays, biological controls or manual labour. These are a regular part of our annual activity schedule. February 's activity was an attempt to use builders plastic to solarize blackbeerry, you can see the result was positive although we tried to use pegs that weere too short and the wind lifted the plastic. When logs or other heavy objects replaced the pegs things worked better. In five months the canes and plants were weakened, if the plastic was held down effectively this appears to be work.
