Hedges and screens can add beauty and privacy to the home landscape. Some people clip hedges for a formal look, and others choose to keep them loosely informal with arching branches. Depending upon the height of the plant materials used in your hedge, they serve many uses:
Figure 1.—A row of crabapples provides a pleasant view from this bank—much more attractive than the adjacent parking lot view, which the trees screen.
If placed close enough, any plant will form a hedge. However, the growth habits of some plants are more conducive than others for hedge-type growth.
Evergreen plants, both broad leaved and narrow leaved, are effective year-around screens, but they are also generally more expensive to install. They stay dense and green all winter long, so you will have the benefit of privacy throughout the whole year. Yews, hollies, and boxwoods make excellent evergreen hedges. Hemlock is a conifer that can be left natural in form,or it can be clipped without the problem of shoot dieback.
Figure 2.—For a thick, interwoven shield of branches, stagger young plants in a double row and place the plants in each row 2-4 feet apart, depending upon the mature size of the plants.
Informal flowering or berrying shrubs are often used as hedges if a year-around visual boundary is not a must. Annual thinning of this type of hedge is necessary to keep it healthy and in vigorous flower-fruit production. Do not shear these plants, but allow them to assume their natural shape. Flowering quinces, forsythias, mock oranges, and barberries are common hedges of this type.
Figure 3.—Prevent wind damage to plants by tying them to a horizontal wire.
Figure 4.—For a formal hedge, shorten newly planted shrubs by half after planting.
Trees can be giant hedges and windbreaks simultaneously. They allow air to filter through and slow it down gradually. Lindens, katsura trees, crabapples, and arborvitaes are examples of tree hedges. An informal staggered arrangement of katsura trees makes a grove-type hedge that can be seen through.
Mixed plantings of trees and shrubs (evergreen and deciduous) make very attractive screens and provide variety that a single plant-type cannot.
Plants may be purchased growing in containers, balled and burlapped (B and B), or bare-root. Bare-root material should be planted only during the spring. Container or B and B plants may be planted anytime the soil is workable. Evergreens should be purchased only as B and B or containerized nursery stock.
Spacings for individual plants vary with the type of nursery stock and their use. For low formal hedges, space the plants 12 to 18 inches apart. Larger plants may be spaced 18 to 30 inches apart. Conifers may be spaced 4 to 6 feet apart if they grow wide at the base. The time required to achieve a hedge effect can be reduced by planting on narrower spacings.
For a double row of hedging, space the rows 18 inches apart. Stagger the plants so no two are directly in front of each other.
A length of cord or twine is useful in defining the location of your row or rows.
The length of time necessary to achieve the desired size of your hedge depends upon the type of plant chosen and its vigor. A dense hedge must be developed slowly. Never try to make the hedge reach its effective height in a single season.
Rapidly growing plants such as privet should be pruned severely the first and second season after planting. Shorten the plants by one-third to one-half their height after planting and after the first growing season. Subsequently, stems should be cut back at least 6 inches every time they grow 1 foot until the desired height is reached. During the entire life of the plant, thinning cuts need to be made to remove old wood.
Figure 5.—Thinning cuts are made as close to the soil as possible. Choose the oldest branches for removal at ground level. Remove any branches that rub others or tend to crowd toward the middle of the plant.
A good hedge is well filled at the base. In formal pruning, trim so that the base is wider than the top. Otherwise, the base of the hedge will be shaded and become thin and open.
Informal plants should be pruned by thinning branches within the shrub and at ground level.
Figure 6.—Keep the base of the plant wider than the top, since light and air make for compact growth top to bottom.
Pine, spruce, and fir screens should be pruned annually by removing the tip bud or shoot on each branch. This technique encourages more compact, denser growth.
Broad-leaved evergreens such as hollies should be pruned just enough to keep the branches in line. Always cut back to side branches or buds.
New plantings should be cultivated frequently or mulched to keep them free of weeds and grass. An annual fertilization of 2 to 4 pounds of 10-10-10 or similar fertilizer per 100 feet of hedge will help to maintain healthy, vigorous plants. The best time to fertilize woody plants is in the late fall. Fertilizer applications should not begin until the first year after planting.
Overgrown, neglected hedges should be removed and replaced with a new, desirable hedge. Neglected hedges are generally impossible to rejuvenate. With the exception of yews, most evergreen plants will not produce new shoots from the old, brown growth. Cutting plants back to within 6 to 12 inches of the soil line is usually a waste of time. Privets are an exception.
|Guidelines for Choosing Hedging-Types of Plant Materials|
|Small Hedges (1 to 5 feet)|

'Prostrata': a prostrate form
'Sherwoodii': a selected dwarf form to 3 ft
'Edward Goucher': has abundant lavender-pink flowers
|Semi-evergreen||White-flushed||Zone 6 plant, but in unusually bad winters, may show dieback. Glossy leaves. Blooms almost continually in summer. Use as informal hedge. Excellent for textural effects. May be a little slow to make a thick hedge. Used often as bank cover, massing, or facing plant. Combines well with broadleaf evergreens.|
|Barberry, Japanese (Berberis thunbergii)
'Atropurpurea': leaves, dark purple.
'Aurea': leaves, citron-yellow.
'Crimson Pygmy': dwarf form, red to purplish leaves in full sun.
'Kobold': dwarf form, green leaves.
'Rosy Glow': green-white leaves overcast with red, new growth is exceptionally red.
'Erecta': upright, compact form. A 28-year-old plant never clipped was 5 ft tall, 10 ft across.
|Deciduous||Yellow outside; 2 to 5 flowered clusters, not showy since borne under leaves.||Red, lustrous||Forms dense, impenetrable border because of single spines.|
