|Readers tulip bed attacked by probably ground squirrels.|
A. You have an interesting story to tell. To my knowledge, rabbits typically focus on foliage. I have not heard of them digging for tulip bulbs.
We have both jackrabbits and the desert cottontail. The Jackrabbit will stand on its hind legs and eat fruit tree limbs and stems up to nearly an inch in diameter. Damage to fruit trees can extend to nearly 3 feet above ground from jackrabbits. I have never had them go after root crops in the Orchard, only the leafy greens including garlic and onions.
Our biggest pest problems for underground crops have been ground squirrels and gophers. As you know golfers attack from the ground but the ground squirrels can do damage similar to what you have observed.
