I'm afraid you don't have a lot of options. You can put an electric barrier up, which is less obvious than a rabbit fence.

You can try other kinds of repellents, Tractor Supply has several choices. I haven't used these, so your mileage may vary: https://www.tractorsupply.com/tsc/product/liquid-fence-deer-rabbit-repellent-40-oz?cm_vc=-10005

You could also just start planting stuff that is not appetizing to rabbits. Nothing is truly rabbit-proof, but there are some they will usually pass up, including:

strap-like foliage, esp from bulbs, like daylilies, daffodils, grape hyacinth, iris

columbine

rough foliage like lantanas and verbena

onion family, like alliums

many salvias

mint family, like bee balm, catnip, and, well, mint

herbs like rosemary, basil and lavender

poisonous plants like foxglove, artemisia, oleander (watch out if you have pets/kids)

"fuzzy" plants like lamb's ear

prickly succulents

nightshade family like tomatoes, eggplant

Good luck!

Thanks. I've done some companion planting especially with mint and society garlic. I'll try arranging a little more and check into some repellents.
