I have 4 SNOWBERRY/ CANDY CORALBERRY. Two look great while one is almost nonexistent (very few leaves and kind of a dull green with some brown and only 6” tall compared to others that are 2.5’ at least). This is year 3 and over the winter each year it seems and animals (deer or rabbit?) are eating all the berries off and chewing the stems down. The shrub that is the worst seemed to have gotten chewed down the most in the winter. Will it never come back?
That’s frustrating! You are right, it might be so stressed by the repeated damage that it won’t come back. Or, won’t ever catch up with the other ones. If you replace it, look at using a deer or rabbit repellent. They do a great job but need to be reapplied throughout the year.
