Bindweed is another problem weed that tends to get into well established plant formations.
This weed has white trumpet-flowers and twines around other plant stems, smothering
them in the process.
They are not easy to remove as they persist from a perennial root system. The roots
are usually white and brittle and, if broken, are able to regenerate from the smallest
sections. Like couch grass the roots need to be removed without leaving any of the
root system in the soil.
Nettles are one the least problem weeds in the allotment as they can be easily removed
by pulling out the complete plant. Obviously make sure when you do this you are wearing
thick garden groves as they do tend to bite. The annual nettle does not have long-lasting
roots, but does produce very large numbers of seeds from an early age. They tend
to relishes fertile soils rich in organic matter.
