Shrubs to Avoid
The following shrubs are often offered as hedge plants, but actually make poor choices in most cases:
- Honeysuckle (Lonicera spp.): Avoid varieties subject to witch’s broom.
- Siberian elm, also called Chinese elm (Ulmus pumila): Popularly sold as a “fast-growing hedge”, Siberian elm is actually a tree and will quickly outgrow its role. It soon loses its lower branches and is highly subject to diseases when heavily pruned.
- Spruce (Picea spp.): Their tendency to thin out at the base and to react badly to harsh pruning make them poor hedge specimens.
- Yew (Taxus spp.): They make excellent hedges in zone 6 and above, but are subject to winter burn in colder climates.
