I've some weeds growing out from underneath the hoppers up in the guttering. They grow in the sight cracks and joints and must love the constant supply of water and nutrients from the decomposing leaves. I've pulled them out as best I can but they keep coming back.
My question is, can anyone recommend a ridiculously strong weedkiller that will kill them off once and for all?
