Shrubs can add beauty and character to any garden, but not all of them are friendly neighbors. Some shrubs, while enticing at first glance, can become a gardener’s nightmare.
Whether it’s their invasive roots, allergenic properties, or high maintenance requirements, these shrubs can bring more trouble than they’re worth. Here, we outline 28 shrubs that experts advise against planting in your yard!

Additionally, its pollen is a notorious allergen, making it a sneezy nightmare for allergy sufferers. It’s also high maintenance, requiring frequent pruning to keep it in check.
