Good luck! I've never found anything that works except a fence at least two feet high. Or cats and dogs with a taste for rabbit. : )

We aren't seeing very many this year after decades of them everywhere. And we have part of our back fence down due to some construction work so they have access to all my roses and perennials. I'm giving credit to my neighbor's cats. They come up and hang out with mine, then stay at night when mine come in. I think they're having a furry midnight snack. ; )

High velocity, air-propelled lead projectiles work well against the ground squirrels in my yard.

I have (or had) 'colonies' of rabbits when I moved into this house here in san clemente 5 yrs ago. Every product on the market did nothing to help. Then I read an article about rabbits in the UK and how they were inately afraid of the smell of fox urine...they knew to stay away for fear of being eaten. Anyway, long story short, If you blend cooking oil, garlic, cayenne pepper, mustard, salt and vinegar together in a blender and zap until smooth, you will create a mixture that has the same smell profiles as fox urine. I know this sounds more like a vinegarette recipe than a rabbit cure, but I swear it works incredibly well. Those rabbits will move out of your yard and as far away as they can get.
2 cups veg oil
1 cup white vinegar
2 heads of garlic (husks removed)
3 tablespoons of cayenne pepper
1 teaspoons of yellow mustard
2 tablespoons of salt

Blend this mixture for quite a while until smooth. Place in an old ketchup container and squirt your rose bushes as well as the soil all around them. Make several batches and be sure to keep the roses and surrounding soil covered for at least a week if not two weeks. Even the most daring rabbit who ignores the smell will be unimpressed with the cayenne pepper if he ventures close...and the oil ensures the mixture sticks to whatever you spray it on. Your garden may smell like garlicy salad dressing for a while, but the rabbits will eventually move out and then you can stop squirting it. Be sure to rinse your roses well to remove the oil once your rabbit problem subsides. Once my rabbits were gone (week and a half later) I followed up with squirting this mixture on the ground around my plants once a month just to repel any new bunnies that might move into the neighborhood. Good luck...I swear it works!

I've had good success at discouraging rabbits using blood meal, which is also an excellent fertilizer. Main problems are that it is attractive to dogs (who shouldn't eat it) and that you need to re-apply it every few weeks. In my last garden I had to resort to rabbit-wire cages for many new plants until they got large enough to withstand a little nibble from the !@#$%^& rabbits. Good luck!
