Planting A Hedge

 Why Plant A Hedge

• Living privacy fence to provide privacy from street traffic and neighbors
• Sound barrier to reduce noise
• Windbreak to reduce harsh winds
• Snow fence to reduce snow accumulation
• Wildlife sanctuary and feed birds

Planning

Select vigorous disease-free and pest-free and resistant plants that suit your region. Wise plant choices make a healthy hedge that's easy to maintain. Slow- and moderate-growing shrubs and trees are best. Fast growing plants require more pruning (hedging).

Your choice of shrubs or seedling trees also should be guided by the style of hedge you want. Formal hedges, with a solid architectural form, neatly frame a yard or rooms within it. Deciduous flowering shrubs, such as lilac, spiraea, forsythia, and evergreens, such as boxwood, arborvitae, holly, develop into effective hedges although much of the flower power is loss. Set the height and depth of the hedge according to the vigor of the plants chosen.

Planning, Measuring and Staking the length of the planting area is next up, followed by shopping for plants, digging, and watering. 

Planting...

1. Stake and mark the planting area, whether in a straight line or a curved one. Use a measuring tape as a guide. Be sure to consider underground utilities when selecting the planting location. Avoid planting over utilities if possible.

2. Space plants set potted shrubs in place, allowing room for the plants to reach their mature size. Stagger plants in two rows for a thicker hedge that will fill in more quickly.

3. Space accordingly based as on the mature width of the shrub as the spacing between the plants' root balls.

4. Dig the planting holes and remove the shrubs from pots and set them at the same dept. Space according to what shrubs you are setting and refill in the planting holes.

5. Water shrubs as needed throughout the first growing season.

6. Mulch - Spread a 2 to 3 inch layer of shredded pine bark mulch between the plants. Keep the mulch away from the plants' stems to allow water to reach the roots.

Willow Oak - A Fine Street / Landscape Tree

Willow oak (Q. phellos)

Willow Oak (Quercus phellos) is medium to large, deciduous tree, part of the "red oak" group (USDA hardiness zones 5-9). It is distinguished for willow-like oak foliage. Growth rate following a 2 year establishment period is moderate (12-16 inches annually).

Willow oak grows 50-75 feet tall and 30-35 feet wide with a rounded top or canopy. Young trees tend to be pyramidal in form. Individual specimens may reach 90 or more feet under ideal site conditions. Its small ¼ – ½ inch nearly round acorns form almost every year, are not a major maintenance headache, and serve as an important food resource for wildlife.

Long stringy yellow-green long catkin flowers appear in April, a few days before leaves emerge. Unlobed 5-inch long leaves mimic those of willow trees (Salix spp.). Leaves are tipped with a single 1-inch wide bristle. Green summer leaf color turns an undistinguished yellow-brown or dull gold very late in autumn. A young tree has a smooth grayish bark which darkens and becomes furrowed with age.

Native to the Southeastern U.S., willow oak prefers a moist bottomland, organic-rich, well-drained soil. This landscape tree tolerates light shade, but performs best in full sun. Willow oak can handle a wide range of soils including clay. Once established, it copes with summer drought well. Foliage is tolerant of urban air pollution.

Willow oak demonstrates good disease and pest resistance and is a long-lived and low-maintenance tree. In a landscape willow oak fits into large sites, such as in public parks or along wide roadways and avenues with good soil mass for adequate moisture. The narrow leathery leaves abscise very late in the fall and make a great loose mulch scattered under other landscape plants.

Kingpin® - new selection of willow oak introduced by Bold Spring Nursery. It offers uniformity in street tree plantings along with these improved traits: darker leaf color, strong central leader (trunk). Kingpin is large 60 x 45 feet shade tree.

Katsura Tree

'Pendula' Katsura tree

Hooray! In American gardens Katsura tree (Cercidiphyllum  japonicum) is finally becoming more planted as a fine landscape tree. There are a number of great varieties to choose. This medium to large growing tree (height depending on cultivar) commands four-seasons appeal. Rated as a medium-sized 40-60 foot pyramidal, this long-lived majestic specimen may top off at 75 feet in height before its first 100 years. 

Its beautiful heart-shaped soft green summer foliage transforms to purple and gold shades in autumn. After the leaves fall they reveal its lovely symmetrical branching and scaly/shaggy bark. Often, the fall air holds a cinnamon scent reminiscent of cotton candy or a sugar-cookie.

Katsura tree is indigenous to Japan and China where it can grow an incredible 100 feet tall (USDA hardiness zones 4-8). The species is dioecious, e.g. separate male and female trees. The tiny flowers are mostly inconspicuous and small pods with numerous winged seeds are dispersed by female trees in late fall. Katsura tree is also not invasive.

Select Cultivars: some 20 varieties are listed, but I mention only 4 here:

'Pendulum' – lovely weeping form 15 to 25 feet tall and 20 to 25 feet wide. Other weeping forms also lumped as 'Pendula'.

‘Morioka Weeping’ - another weeping form, 20 feet tall and 15 feet wide, with more upright growing branches when young and  large leaves.  

‘Red Fox’ (‘Rotfuchs’) – 30-foot pyramidal tree; new spring reddish purple foliage, turns dark bronze-green in summer and orange-bronze fall color.

‘Claim Jumper’ - a relatively new gold-leaved variety that grows 25-30 feet (8-10 m) and 20 feet wide. Leaves emerge with a pink blush and unfurl to soft golden-yellow. Gold leaf color fades away by late summer.

Katsura tree is easily grown in a moist well-drained soil and in full sun to part-shade. Growth rate is equal to a sugar or red maples. Newly planted 1-2 year old trees are particularly prone to leaf scorch. During its first year or two after planting, katsura is susceptible to long dry spells and will need irrigation in periods of no significant rainfall.

Katsura are rarely troubled by serious pests or disease problems. Katsura tree and cultivars are sold at full-service garden centers, but smart gardeners are likely to quickly buy up the inventory. Rare or new cultivars, like some that are listed here, are sold by on-line specialty nurseries.
