get rid of them ? I've tried repellents, both commercial and homemade varieties and don't want to resort to using my.22 . Fencing is not a viable option either. Any suggestions ?
While I appreciate the suggestions a cat is not possible as the garden is at a school. I've tried the hair trick in many forms to no avail and am willing to try the other mixture suggested but fear it is just another variation on a theme which has yet to work for me.

Mix 1 tablespoon of baby shampoo and 1 tablespoon of ammonia in a quart of water, and spray every third evening.

You can also wrap bunches of dog and cat hair (available from a local groomer) in old pantyhose, and hang them from various areas in and around your garden.

you could stop by a barber and get some hair from someones haircut or cut your own. this has human scent that will not go away, therefore scaring rabbits off. simple and cost effective.

Get that time-tested varmint-catcher, the cat. >^..^<

i don't know about all these other methods but I do know that there is a .....i believe it's dried deer blood that u sprinkle around u'r garden along w/ marigolds. My folks used it for their garden & it keep the bunnies from have din-din @ u'r expense. Ck. w/ u'r local garden shop. They should have it. Don't use chemicals... this does work.

If you cut 1-2 foot lengths of old garden hose, and place them amoungst the plants, it's supposed to repel rabbits. The hose is meant to look like a snake to the rabbits, so they stay away. You would probably need to move the hose around every few days, just to keep them from becoming accustomed to it.

We used ivory soap.
cut it up and put it on sticks around the garden.
Also, marigolds are supposed to be helpful.
