I wish I could get more rabbit droppings for my lawn. It is great fertilizer. Do rake it into your lawn. You will notice that part of your lawn looking better than the rest over time.

Yeah, its free fertilizer. If you've got ornamentals you want to keep them out of there are waxy hot pepper sprays that will deter them. Bloodmeal sometimes acts as a repellant and if you wanna get hardcore human urine usually does the trick too.

One of the benefits of an organic program is that you get more critters coming to your lawn to leave droppings. At most I would get a rake to spread them around.

If you really want to discourage bunnies, give them something to do and then criticize them for no reason both while they are doing it and after they have finished the task. Or if they use their own initiative to do something, you have another opportunity to criticize them for not paying attention to what they were supposed to be doing. Oh, here's another way. Give them a task and then take it away from them when they don't finish it early. Then give the same task to a second bunny that the first bunny does not respect. Ooooooh, that will really discourage them.

Its good to know even organic gardeners have a sense of humour! I tried your advice but whenever I opened the patio door to start criticizing them, they just bolted. Apparently they know whats coming and they are very sensitive to such personal attacks. I'll try raking instead.
