those wascally wabbits!
Now that the snow is finally melting here in Central Iowa, the extent of damage to shrubs from rabbits is woefully apparent. Snow cover was deep for so long that bunnies fed on almost any plant that protruded from the white stuff.
It’s discouraging to look at receding snowbanks and see glaring white stems of shrubs stripped of their bark. Often, the shoots near the ground are fine because they were protected under the snow.
It’s too late to protect these shrubs now. But they can be salvaged with a little pruning. If stem tips are gnawed, cut the remaining stem just above a bud. A new shoot will emerge from that bud. If the bark of larger stems is damaged, the amount of pruning needed depends on the extent of the damage. The rule of thumb that I use is, if the bark is stripped more than half way around the stem, remove that shoot. If damage extends only 1/4 (or less) of the way around the stem, it will probably continue to grow fine without any care.
I usually opt for removing damaged stems. Shrubs with multiple shoots resprout readily from the base and grow back fuller and lusher than ever. It’s a great opportunity to rejuvenate old, overgrown shrubs. Make cuts 6 to 12 inches above the ground. If you make the cuts higher, the shrub will develop tufts of new growth at stem tips and be relatively bare at the base.
One technique that I’ve used to protect shrubs from rabbits is to place homemade tomato cages around smaller shrubs. They’re cylinders made of rabbit fencing. The lower wires are close together, preventing rabbits from getting in. Wider wire spacing at the top allows easy access for tomato harvest in summer. Normally this trick not only solves the problem of where to store cages over winter, bit it also prevents rabbit damage to the shrub it encircles. However, deep snow this year let the rabbits wiggle through the wider wires. Next year I’ll be more vigilant and spray rabbit repellent in addition to fencing off favorite plants.
