Dead plants - weird root thing?!

The green netting you suggest sounds like a plan. We used similar to keep the chickens out of the borders when they were freshly planted - under supervision they were fine with it. Just make sure you make the fencing high enough to discourage inquisitive rabbits leaning on the top of the netting to get to the plants about them and bringing the whole fencing down.

You can buy rolls of tough plastic netting at Homebase. I think it's used for ground protection on grass where cars drive frequently. Can't remember the price, but it comes in a roll and can be cut in half with secateurs or sharp scissors - at this height it was able to discourage the chickens so it should work with rabbits. Use bamboo cut into required amounts, threaded through the netting as "fence" poles and bingo. If you put it up early in the year, the plants will mask 95% of it when they grow.

HTH?

 

Whatever netting you choose, make sure the holes are no more than about an inch across, we don;t want your bunnies getting their head stuck in it when you're not looking do we. Also, if you choose plastic netting, just be aware that rabbits can chew through it if they are determined enough. That probably won't be a problem in you case, as I can't imagine well fed rabbits being determined enough to go to such great lengths, but it is something to be aware of.
