Weed removal and control?
I am a relatively new gardener living in coastal Sounthern California, using permaculture and sustainable methods for replacing existing lawns with edible landscape. My problem is weeds.
This property, which was purchased last year, had been neglected for over 30 years and all of the lawn areas consist of kikuyu, bermuda, crab grass, and other weeds. In some areas I've manually removed the lawn and placed heavy sheet mulch down only to have bindweed, kikuyu, and crab grasses come up through the mulch. In these areas, I've had some success removing individual weeds as they emerge, but bindweed is especially difficult to remove.
Recently I met with a local Master Gardener who identified herself as organic and sustainable, yet she stated that the only way get rid of weeds is to use products such as Round-Up, fluazifop-butyl, or sethoxydim. I was shocked and disappointed that the only solution she had was to use these chemicals.
Is there a better way to get rid of these weeds? What do you suggest for large areas? Would love to hear your suggestions on organic methods for weed removal.
