I have been running an experiment weeding the Garlic with ducks, as it is just too much for My daughter and I [mostly her] to keep up with, and now that it is expanding -something must change, so-- the only options I could think of were- weeding geese , or ducks, [and geese are a pain] and khaki Campbell ducks lay good eggs- or selective herbicide [and I hate chemicals, and have done everything organically ] - so-- the duck experiment began- I fenced off a section of the garic field and put our 8 ducks in it, and monitored them to see what they ate and how much garlic they ate, --- The ducks ate very little garlic, and lots of weeds, almost all of the weed varieties ,-but they need water close as they don't want to eat much before they want to "wash it down" - I noticed that when the sprinklers were on they ate a lot more weeds further out in the field when they were wet, so- I will have to think about that one as water is scarce here and we have watering days about every 2 weeks,[for farmers, not house gardens] -but I might be able to turn it on for just a few min in the am to wet the weeds and then turn it off. But- my garlic patch is a little too big to get by calling it a "house, or kitchen garden"-- any way I now have more duck eggs in the incubator.....
