So did the bugs do it?
•Enough sun? 
Gardens need at least six hours of sunlight.
•Over or under watering? 
Should be about 1 inch per week.
•Bad weather? 
Hail, wind , extreme heat, cold, or humidity.
•Critter problems?
Rabbits, voles, mice, dogs, cats
Before blaming the bugs check out the plant’s environment.
Not one of these?
