Lots of suggestions from Cheryl, they sound good and practical, a sure way to keep the rabbits out is of course a fence started below ground or wire mesh. You need a physical boundary for effective results.
Odor repellants need to be reapplied and that requires vigilance on your part. Best to you.
Create a simple wall around your garden to keep them out.
Hi Joanne - those little monsters! I've had the best luck with a product called Liquid Fence. For really tasty plants, I will make little cylinder type fences to put around the plant for protection. If you having problems with your veggie garden, I would just recommend fencing it in. Just keep trying different things and good luck!
