Trimming your landscape hedges will not only keep them looking beautiful but it also helps their growth form over time.
A hedge is a naturally trimmed shrub planted in line to form aesthetic living fences. These all-natural borders create privacy and establish boundaries.
There are multiple options when creating a hedge. An informal hedge is low maintenance, while the formal hedge requires heavy pruning of shrubs, as seen in most traditional gardens.
There is no exact rule of when to trim your hedge. However, knowing what type of trim it needs will allow you to determine when the perfect time will be and how to do it. After all, providing good care will make your hedge the best hedge it can be.
So, let’s learn how and when to trim your hedges.
When Should I Trim My Hedges?
Keeping your hedges in good shape requires a few simple steps. One important aspect to keep in mind is what are you trimming? Is it a newly planted hedge, or are you trying to reform the aging established bush? If so, when to trim will be entirely different in those two scenarios.
Also, knowing the perfect time to trim bushes depends on the plant you have. Cutting back species like forsythia is done annually to maintain shape. In fact, these branches spread like a beautiful perimeter for your spring designs.
Slow-growing shrubs like viburnum require pruning every five years, which is why only prune when necessary. Climbing roses, on the other hand, need pruning when roots are fully established after three years.
With that being said, do your pruning when you see dead and diseased branches or when plants have overgrown and are out of shape.
The primary goal of formative pruning is to control the future shape of the plant and develop a balanced structure and an equal spread of branches and foliage.
- Newly Planted Hedge
New hedges need formative pruning to keep the plant in shape while the roots establish gradually.
This type of pruning is usually done in early spring or winter before plants are actively growing in summer or the fall.
Trimming newly planted hedges before the buds break or before the plants go dormant, will encourage a more developed branching and a more compact shape when it resumes growth in the spring. Besides, it will take less effort to shape and maintain the plant when it reaches maturity.
- Deciduous Hedge
Most deciduous hedges like hawthorn and hazel are best cut in June and September. However, trimming beech and hornbeam should be no later than mid-July if you want the persistent winter leaves. Pruning projects when the plants go dormant give better results, so avoid cutting back plants during a dry summer.
Barberry shrubs hardy in USDA zones 5 through 9 only require light heading to maintain the height and width.
Pruning in the spring to eliminate broken and overgrown branches can keep these hedges healthy and compact and remain attractive throughout the summer.
- Evergreen Hedge
Evergreen hedges are vigorous plants you can trim at least twice a year. But frequent pruning may result in a denser hedge.
Trimming in late spring or early summer gets your project done quickly by targeting the new growth branches using shears or a powered trimmer.
Cutting later in summer needs a more time-consuming cut with pruners because of a looser hedge.
- Flowering Hedge
Flowering hedges are delicate, and pruning at the wrong time can prevent them from producing flowers the following season. Flowering shrubs like camellias hardy in USDA zones 6 through 9 require spring pruning.
Trimming the plants that produce new buds on old wood right after they finish the season blooming will ensure plenty of flowers to carry the following display.
Maintenance trimming helps to keep the balance between healthy growth and beautiful shape, this is quite essential. Usually, trimming happens about three times over the entire summer.
However, you should not cut back more than 25% of the growth and a depth of 1 to 3 inches on your hedges to avoid damage. Unnecessary extensive trimming can likely cause a detrimental condition to your borders.
Maintaining specific shapes like balls in your shrubbery requires an initial trim in early summer and is best done with multiple attempts the entire season.
Topiaries and hedges in Japanese gardens receive a simple trim while they are young. It helps train an attractive tree in several shapes.
An old hedge can receive a new form with more modification to its shapes, and with regular trimming maintenance.
But remember to observe the weather impacts upon your topiary. Calculate your heading approach frequently to prevent adverse consequences on your shrub foliage due to over trimming.
- Maintaining a Formal Hedge
Keeping a well kept and tidy look of formal hedges adds style and aesthetic value to your property. However, a well-shaped shrub is no accident. It was trained carefully since the beginning of the plant’s life.
Regardless of the type and species, new hedges should undergo formative pruning in their early years to form shapes and make them healthy. And then, low maintenance is necessary when hedges are fully established.
Maintaining overgrown and poorly shaped hedges is time-consuming and requires proper techniques. So, let’s not have our hedge get to that point.
Regular pruning is essential to achieve the desired shape and you must keep the top of the hedge narrower than the bottom section, this will help in shaping your hedge the right way.
Hedges are often shaped with flat tops and vertical sides, but these shapes aren’t always successful. Rounded and pyramidal shapes are found to be the most flourishing in shaping hedges.
Sunlight is essential to keep these plants healthy, and the pyramid shape allows the lower branches and foliage to receive an adequate amount to produce a denser hedge.
Knowing the natural growth habit of your hedge species is also a factor you have to consider. Getting plants that grow fast and require frequent pruning to maintain the height you prefer is exhausting and can be very frustrating.
- Pruning Large Leave Hedges
Broad leaves, camellias, azaleas, pyracantha, and hollies require slight pruning to remove weak and old stems. These plants flourish with very minimal pruning to keep them neat.
Over-trimming of the hedge will cause lesser flowers the following season. But cutting back about 6 to 8 inches from the ground, when the plant is old and misshaped before the spring growth begins will encourage fresh shoots.
Some gardeners prefer to prune ⅓ of the branches and retain the general shape of the plant, and this technique is effective short-term. In the long run, overgrown broad-leaved evergreens are best to be removed and replaced.
Properly trimmed hedges are not only attractive, but they are lush and healthy. Cutting back recent shoots can make the living fence dense and crisp, and these are possible upon using the right trimmers.
