KitCMC aaaargh! I have so many rabbit issues, but not in my dahlia garden, which is fenced, within another fence, with my dog hanging out between the two fences. Ideal!
But in the rest of my yard, I use a few different methods to foil the bunnies. What might work best for you is to buy a bunch of wire wastebaskets from the dollar store and tack them down over the plant with lawn staples. It’s a pretty quick and easy temporary fix.
Liquid fence, or similar pest deterrent products also work well, but you have to reapply religiously, especially after rain or overhead watering.
