Trees, Shrubs, and Vines for Low Maintenance Landscapes
Trees, shrubs and vines are integral parts of the landscape, providing wildlife habitat, beauty and shade to a property. Plants modify the immediate environment by altering the microclimate surrounding them, reducing noise and trapping air pollutants. In addition to their aesthetic and environmental value, woody ornamentals often represent a considerable financial investment in the landscape.
When choosing woody ornamentals for the landscape, it is important to look for characteristics that make a plant a " high value" selection. The ideal plant is one that is tolerant of environmental stress factors such as drought, poor soil conditions and air pollution. It would have few insect or disease problems that might require management. In addition, it would have good form and multi-seasonal interest. While no one plant can be considered ideal, plants that are structurally weak, short lived or intolerant of environmental stresses will require a higher degree of maintenance.
The axiom "the right plant for the right place" is particularly true for woody ornamentals. When selecting plants for the landscape, mature height and spread must be considered as well as the conditions and limitations of the planting site. A woody ornamental planted in the wrong location may fail to thrive, need increased maintenance or become an out-of-scale landscape feature, thus losing its value to the property.
The first step in ensuring good plant health is choosing a recommended low maintenance plant and planting it in the correct location. However, planting practices will also affect plant health. Improper planting techniques or inadequate site preparations usually cause woody plants to decline in vigor or fail. Some common practices that often result in plant failure are:
- planting at the wrong depth (too deep/too shallow)
- soil compaction from heavy equipment, etc.
- insufficient removal of burlap, twine, etc.
- deep mulching up to and against the bark
- mower damage, string trimmer injury or herbicide damage as a result of turf growing up to the trunk
- too much or too little water
The following list of woody ornamentals shares certain characteristics that make them deserving of increased use: reduced maintenance requirements, increased drought tolerance, non-invasive nature, winter hardiness and year round interest. Many are native to North America and would be useful alternatives for invasive species. Unless noted, they have no significant insect or disease problems.
Some may be difficult to locate but their desirable traits make the search worthwhile.

New hybrids of C. kousa x C. nuttalli (the “Jersey Star” series) are also resistant to dogwood anthracnose as well as powdery mildew; check for hardiness. C. florida ‘Appalachian Spring’ is reputed to be resistant to dogwood anthracnose. |

PinesMany two and three needled pines (Pinus species) are commonly used in the landscape. While ornamentally useful, these pines have a complement of insects and diseases that make them high maintenance trees due to the need for annual and timely applications of pesticides. Pines such as the Austrian pine (Pinus nigra), Red pine (P. resinosa), Mugo pine (P. mugo) and Japanese Black pine (P. thunbergii) are subject to shoot blight (Sphaeropsis/Diplodia), pine shoot moths, scale insects and borers such as the black turpentine beetle; all of which may disfigure or kill these pines. The following five needle pines, while not entirely pest free, may be subject to insects that cause damage that is mainly aesthetic and not usually fatal. The primary insect pest of five needle pines is the white pine weevil, which attacks the central leader, causing it to die back to a lower set of lateral branches. While temporarily disfiguring, a new leader may be established by bracing one of the lateral branches into an upright position or, if left alone, will often produce a new leader from a lateral on its own. |

Witch HazelsThe witch hazels (Hamamelis species) are a group of hardy shrubs that deserve greater use in the landscape. These shrubs are generally problem free and offer color in the garden at a time of year when little else is of interest. The following species are listed in sequence of bloom from January, February, March and November. Each is in bloom for an extended period of time as the ribbon-like petals curl up during freezing weather. |

SumacsThe Sumacs (Rhus species) are a group of durable shrubs that can form large colonies as they sucker freely from the base. Many of the best species for landscape application are native to North America. Excellent for massing on embankments or for naturalized areas, they should be sited with care due to suckering. |
