Weeds along fences

Often vegetable gardens need to be fenced to keep out rabbits, groundhogs, deer and dogs. Keeping areas next to fences from becoming weedy is important because (i) annual weeds may shed seeds from there into the garden, (ii) some perennial weeds along fences can spread several feet into the garden by underground roots and rhizomes (for example, quackgrass, hedge bindweed, and Canada thistle), and (iii) tall vegetation along fences may block light from neighboring crop plants. Fences form ideal support for hedge bindweed and other vining weeds.

Various control measures are possible. Brick or concrete pavers, or a heavy layer of bark mulch can be used to reduce weeds by forming a path along the fence. Hoeing is often ineffective because the fence protects the weeds. Hand pulling is effective but laborious. Repeated use of a string trimmer is the most usual method for controlling weeds along garden fences. Flame Weeding is effective if done frequently enough to keep the weeds small and provided no straw or bark mulch is adjacent to the fence to catch fire.
