Which pungent material can be scattered around asters as a homemade deterrent?
Answer
Blood meal
When physical barriers are deemed impractical or undesirable for aesthetic reasons, gardeners often turn to odor-based repellents. Among the homemade options frequently employed are strong, pungent materials that can be scattered around the base of the target plants. Blood meal is one such material explicitly cited for its strong odor that acts as a deterrent, encouraging rabbits to browse elsewhere. Bone meal is another similar substance suggested for this purpose. It is important to note that these granular odor deterrents often have a short lifespan, necessitating frequent reapplication, particularly following rainfall or heavy watering cycles.
