DeweyRooter said:I used the plastic fork method to protect my veggie seedlings from my cats, who like to dig in the raised bed. So far it has really worked. I have heard the forks also discourage rabbits and other critters. It might be worth a try.

I've just pulled out the forks recently as the seedlings are now big enough.
I do this with packets of cocktail sticks. I can buy a pack of 500 for a buck at the dollar store then plant them all round my plants in defensive positions. wooden BBQ skewers also work really well in amongst the cocktail sticks (pointy bit facing up and outwards), as do defensive rings of chicken-wire. However, they may work too well. When it comes to weeding I stab myself oh-so-many times! Another great thing is chilli or cayenne powder sprinkled around the plants you want to save (I use 100,000 on the Scoville scale
https://www.amazon.com/dp/B01BE05NUQ/). Rabbits have super-sensitive noses, so detest anything strong smelling. We also plant a defensive ring of marigolds around our vegetable patch as those plants stink. That works really well to deter rabbits and skunks (and is said to also deter the bad nematodes underground, but I have no evidence of that). Squirrels we occasionally will still get a visitor, however. For those I use a 1% peppermint oil spray, which may or may-not also work for rabbits.
There are also systemic repellents which are supposed to make plants taste yucky once absorbed:

Lots of interesting strategies out there. Even solar-powered ultrasonic motion-detection repellers (or equivalent using a sensor linked to a water sprayer).
Or you can buy female cayote urine and attract males to come and then eat the rabbits while looking for a mate.
But the absolute cheapest way to deter rabbits may be to just pee on your own garden! Humans are apex predators, and rabbits apparently do not like the smell of human urine (and the nitrogen is awesome for the plants).
