I was wondering where my bunnies had gone! Seriously, I usually don't fertilize at all in summer since we are on fert restrictions here so I 'feed' my plants with alfalfa pellets. A nice slow-release nitrogen boost with soil amending qualities.
I had run out of pellets and finally the feed store got a new shipment. As soon as I started putting down the pellets again, the bunnies have re-appeared. I have cottontails like yours, Bill and also marsh rabbits that are darker brown, smaller and very cute.
If the bunnies are eating my alfalfa pellets, I guess the plants are probably benefiting anyway from their poop. Maybe I'll need to train them where to go . . .
