I see Mollison suggesting canna and lemongrass plantings around gardens to block invasive weeds from spreading in.
There are weeds around my place that could really use a good thick barrier as well! Any ideas?
I likely need about 120-150'.... I guess it gets really expensive if you need to buy plants doesn't it?
Thanks for any ideas!
Thanks for the reply.
Trying to keep out canary reed grass, super invasive yet shallow rooted. Mollison mentioned how tropical weeds were pretty awful so maybe they are as bad as CRG.
Comfrey is a good idea- I'm guessing it spreads if you damage the roots? It spreads quite well for me without any fiddling- however maybe just hoeing around the edge of the barrier monthly will keep it from encroaching. Hmm. Weeds.
Bulbs our great for keeping the weeds out: garlic, flowers (lily), and even onions. Last year I used a comfrey in one corner of my garden, but it got really large so I used taller flowers such as lemon balm or black-eyed susan to provide some break between weeds and garden area.
