We have a problem with flax bushes, green ones and red ones. If they're not growing at tghe back of us then they're poping out of the front of the house. Might I add they do a good jovb at the front. They don't look too good with the rose bushes and the otyher flowers that are trying to grow there as well. Does anyone know how to get rid of them - we are wanting to weed mat the garden and then bark it, but can't do anything until we deal with the flax first.
