Last year my property and surrounding area was rather free from Ambrosia ie common ragweed (Ambrosia artemisiifolia) and now it is everywhere... probably because no-one in this country (Bosnia) is really trying to eradicate (regardless it is required by law).
Is there efficient way to eradicate or at least keep Ambrosia under control, since it is highly allergenic and very invasive?
Should I even bother to fight against it (mowing and pulling before flowering), if no-one else is trying? Would herbicides help (although I'd rather not use them)? Is this lost battle?
