Our gal's are working on our fall garden now. We want to expand the fall garden a bit and have them in the area where it will be. They're doing the weed and grass removal, some pre-tilling, and a little bit of fertilizing. When they get that area bare, we'll move them to another spot that we want to expand and till the area they're now in. Will probably bring them back to the tilled area for grub and insect removal prior to planting for the fall.
Our fall plan is to move them into different sections of the garden as veggie production ends for "clean up". We then use green metal fencing stakes and 4 ft. tall plastic poultry netting to keep them in the area we want them to work in. The stakes and netting are easy to move and re-arrange for the next section.
We don't want them in the garden while it's actively growing as we don't want them to eat the veggies or destroy the plants. We have them assist us with before and after growing season chores. We do share veggies with them and they look forward to their morning cucumber treat but I'm not sharing the tomato's!
