The Green Mound Juniper, Juniperus procumbens 'Nana,' is a versatile and attractive shrub that should be in every gardener's toolbox. It has deep green foliage with just a hint of blue in it that remains on the bush throughout the year. Its superpower is the plant's ability to adapt to whatever form is needed. It's an excellent choice for sloping areas; for example, where it is both ornamental as well as erosion-busting. It looks lovely draped over a retaining wall or in a rock garden. Although it remains petite in height, it can also be grown up a trellis to do the work of much taller shrubs. It is even valued by bonsai artists for the ease with which it assumes desired shapes. Here are a few more reasons to consider the Green Mound Juniper for your garden:
- It is the winner of the prestigious “Award of Garden Merit” from the Royal Horticultural Society.
- It grows easily throughout most of the continental U.S.
- It is low maintenance with little pruning needed.
The Green Mound Juniper does best in full sun—6 to 8 hours of direct sunlight a day.
Water whenever the soil two inches from the surface is dry; more often in very dry weather.
Fertilize in spring and fall with a balanced, slow-release product designed for landscape trees and shrubs.
Planting and Care
Site your Green Mound Juniper in well-drained soil where it will receive at least six hours of direct sunlight a day. Unpot your shrub and tease out any encircling roots, which can girdle the shrub and kill it slowly. Dig a hole that’s as deep as the root ball and twice as wide. Place the shrub in the hole, spreading out the roots. Holding the plant upright and steady, fill in around the root ball with topsoil and tamp down as you go to eliminate air pockets. Water thoroughly. Apply a two to three-inch layer of organic mulch such as bark chips around the root zone to conserve moisture and hinder weed growth, but don’t let it touch the trunk to avoid problems with rot.
Watering and nutrients
When newly planted, water your juniper every few days until you see robust new growth starting on the branches. Then, cut back to only watering once a week and proceed to water for the rest of the first season. An established plant only needs watering when the soil two inches below the surface is dry. This may happen frequently when it is very hot or dry out; so, give the shrub more water at those times. Fertilize according to package directions with a balanced, slow-release fertilizer that is designed for landscape trees and shrubs.
The Green Mound Juniper does not need annual pruning unless you are growing your shrub as a bonsai or wish to use it as a topiary. Monitor your shrub for dead, diseased or damaged limbs, and cut these out whenever you see them. Other than that, you can allow the shrub to grow naturally.
Pests, diseases and animals
The Green Mound Juniper is not prone to many pests or diseases—another reason it’s an easy plant to grow. Spider mites and aphids may show up on the plants, but these should not be a problem for a healthy plant. If insect pressure is severe, consider releasing beneficial insects such as ladybugs and lacewings, which will eat them. Some junipers have a tendency toward blight diseases, such as juniper tip blight, which is most often seen on newly transplanted trees. Plant bushes far enough apart to allow for good air circulation and prune out any diseased branch tips.
Achieving maximum results
The Green Mound Juniper is easily grown as a container planting, where it will naturally begin to spill over the side of the planter as it matures. It can also be pruned into a more formal shape and encouraged to grow in a more vertical fashion. Growing in a container is no different from growing in the ground. Use a high-quality potting mix and pick a container that is roughly twice the size of the root ball with good drainage in the bottom. Note that you may need to water your shrub more often, especially during hot weather, and be diligent about feeding it regularly.
How big will my Green Mound Juniper grow?
When left to grow on its own, the Green Mound Juniper will grow to about a foot tall, and 4 to 6 feet wide. This horizontal attitude makes it an excellent ground cover for slopes or other areas. When planting, however, be careful not to place the shrubs too close together, which hinders air circulation and may encourage fungal diseases.
Where does the Green Mound Juniper grow best?
This hardy little shrub can be grown anywhere where the temperatures do not go below -20 degrees Fahrenheit. That includes most of the continental U.S. except for the most southern and northern sections of the country.
Does the Green Mound Juniper lose its leaves in winter?
No, this bush is an evergreen. Even in the winter garden, when there is little else to interest the eye, your Green Mound Juniper will delight viewers with its deep green foliage, which adds textural interest wherever it's placed.
