PRUNING DECIDUOUS SHRUBS

To prune or not to prune? That is one of the most often asked questions. One of the first chores that we attack in our gardens each spring is pruning, but I find that most people are not quite sure what it is that they are supposed to do. Knowing the proper pruning times and proper pruning techniques seem to be the most misunderstood areas of gardening. Pruning promotes flowering, reduces pests and contributes to the plant’s overall health, all while helping it maintain an attractive shape. The longevity of a plant, its productivity and the overall health of a plant is mainly determined by how well it has been pruned over the years, so it is very important to know and understand the proper way to prune your shrubs. 

When To Prune

In general, the best time to prune most deciduous woody plants is just before the new growth starts in the spring or, in other words, late dormant period (early March to mid -April). Pruning at other times can rob the plant of its stored food and energy. It may also mean a loss of flowers or fruit.

With that said, all rules have some exceptions. Here are those exceptions:

  1. Any early spring flowering plants (plants that bloom off old wood) should be pruned immediately after flowering and before leaves unfold. These are some plants that this exception applies to: Magnolia, Forsythia, Wisteria, Serviceberry, Lilac, Quince, Bridal Wreath Spirea, Viburnums, Serviceberry and Wisteria
  2. Trees such as Maples (including Japanese Maples), Flowering Dogwoods, Birch and Elm, Poplar, Laburnum and Lindens will bleed if pruned in late winter or early spring. A better time to prune these trees would be mid-summer to early fall.

Where To Start – THE 3 D’s OF PRUNING

Many people, when pruning deciduous trees and shrubs, will just shear back the top of the plant to reduce the overall height of the plant, but this is only a part of proper pruning techniques. So what else is involved in pruning? What steps should be taken when starting to prune?

Step 1. When pruning any shrub or tree, you always start out with the 3 D’s of pruning. This means that you prune out any DEAD, DISEASED or DAMAGED branches first.CrossingBranches

Step 2.   Remove any branches that closely cross with other branches or that cross through the middles of the plant. You want to have branches that come from the center of the plant and heads outward.

Step 3. The next step is to consider your pruning goal.  Read below to discover your goal.

How To Prune – Knowing Your Pruning Goal

When pruning any plant, it is always good to know what your goal is and that will help you determine how to best prune your shrub. Here are the 5 main goals of pruning and the questions that you should be asking yourself before you begin:

GOAL 1 – Control the Size of PlantPruning

The best way to control the size of a plant is by natural pruning. Natural pruning means that you are making selective cuts in order to thin or reduce the overall size of the plant. This cannot be done with shears, but with secateurs or loppers. It means cutting one stem at a time and not just shearing off the tips. When all you do is shear back the tips, the plant loses its natural form because it increases the number of branches and creates a branch structure that resembles a candelabra. Your shrubs will become very wide at the top because of this increased branching, giving your shrub an ice cream cone-like appearance. And because the top is so wide, it stops the sunlight from hitting the base of the plant and you are left with a plant that is bare at the base. Always prune back to a point just above a side shoot or back to just above a bud. When pruning is completed it should look like no cuts have been made. It should still have its natural form.

GOAL 2 – Increase the Amount of Flowers and Fruit

Proper pruning will aid in the production of more flowers and more flowers produce more fruit. Most flowers are produced on the tips of the stems, therefore, the more tips that there are, the more flowers that the plant will produce and the more flowers you have the fruit will be produced. In order to accomplish this goal, you cut back the stem tips, stimulating the side branches and developing more tips for the flowers to form on. Just remember that the more flowers that a plant produces the smaller the flowers will be. Fewer flowers usually mean larger flowers.

GOAL 3 – Maintain a Certain ShapeFormal Hedge Pruning

One of the goals of pruning might be to maintain a certain shape such as a hedge, a globe form, or specimen plants like spirals and pompons. This is best achieved by shearing. With shearing you are just removing new tip growth, creating a full dense look. Even though electric shears makes the job easier, hand shears make a much nicer job of things. Electric shears just tear the plant tissue while hand shears makes a cleaner cut. When the plant tissue is torn there is more die back at the tips giving the sheared shrub a brownish tinge. Always make sure that any pruning tool is sharp and clean before using to prevent this from happening.

GOAL 4 – Encourage Colourful Bark

There are certain plants, such as red or yellow twig Dogwoods and Japanese Kerria, which have colourful bark. In order to keep the colours as intense as possible special pruning is required. It is the youngest stems that will give you the brightest colour. As the stems age, they start to lose their colour. So the best way to encourage colourful bark is by pruning out (right to the ground) one third of the oldest growth every year. You will be able to tell which ones are the oldest stems because they will be thicker and more grayish/brown in colour. This encourages new growth to come up from the base, which will then give you more colourful bark.

GOAL 5 – Rejuvenate an Older ShrubRemoving Old Wood

In most cases, we tend to let shrubs grow and grow and once they become too large, we hack them back hoping that they will survive and become beautiful again. It is much easier to do a bit of pruning every year than to wait until the shrub is out of control. It is sometimes very hard to rejuvenate an old shrub that has been ignored for too long. The best way to rejuvenate an old flowering shrub is to do so over a three-year period. This can be achieved by removing one third of the oldest growth every year right back to the base, which will then stimulate growth to come from lower down. In three years you will have completely rejuvenated the entire shrub. With some flowering shrubs you can drastically cut the stems back to about 4”-6” above the ground. It may look funny for that season, but it will fill back in eventually.

I hope that this helps you to tackle your pruning chores this spring.  Happy pruning!

The Five Senses Of Garden Design

Picture this….you walk into a beautiful garden. Your eyes immediately begin to take in the beautiful array of bold colours; from the bright golden yellow Coreopsis to the deep, violet, spiked flowers of the Salvia. You are drawn in by the overwhelming sweet fragrance of a lilac in bloom. In the background, a cluster of birds are twittering back and forth with excitement. As you stroll around the gardens you can’t help but to reach down and touch the soft, fuzzy, silver leaves of the Lamb’s Ear.

All of your senses are alert in the garden, taking in all that nature has to offer you. The garden stimulates your senses of sight, sound, smell, touch and taste. When speaking of gardens and their design, though, there is another set of 5 senses to consider:

A Sense of Entry Before you even arrive in the garden you need to create an entrance, something that invites you to enter and entices you to want to see more. This can be achieved in various ways through the use of an arbour, gate, and portal or with the use of plants. The entrance should be welcoming, giving glimpses of the garden without giving up all of the garden’s secrets.

A Sense of Welcome  A garden must welcome you in. As soon as you enter the garden you should feel your blood pressure going down, feel relaxed and instantly at home. It should be a place where you would just want to find a comfortable seat in a shaded corner and spend the day. Your guests will not want to go home. If your garden is lacking organization, unity and a sense of balance it will leave you feeling chaotic and uneasy. One of the best ways to create a sense of welcome is to make sure that you add elements that stimulate the sense of sight, sound, smell, touch and taste; whether it be the soft trickle of a water feature or brushing by a hedge of lavender as you stroll along the walkway.

A Sense of Enclosure   A small city garden as well as a large country estate with wide open spaces can leave you feeling exposed to your surroundings. For one to feel at home and at peace in the garden, you need something that defines the garden space; to clarify the perimeters of a garden area. When sitting out in middle of your backyard leaves you feeling totally exposed to neighbouring houses, you are unlikely to spend time enjoying your garden. Disguise any unwanted views using a mixture of privacy plants or constructed screens. A larger shade tree that provides an overhead canopy can also give you that feeling of enclosure.

A Sense of Flow   The flow of a garden refers to the way that people move through the space.   It can be the mere outline of the beds that visually leads the eye continuously around the garden. It can be in the form of a path that leads the eye and the feet in ways that maintains your interest and possibly offers the odd hidden surprise. The repetitive use of certain plants throughout the garden can also create a sense of flow and helps your eye to move around the yard. When the lines in the garden abruptly stop, so do your eyes. Simply flaring the line of a bed or walkway out ward instead of inward can make all the difference.

A Sense of Place  A well designed garden has a sense of place. Your garden should look like it belongs there or that it always has been there. It should share some of the same characteristics of the house or its’ surroundings. For example, if you live on or near the Niagara Escarpment you may want to consider incorporating mossy, limestone rocks into your landscape. Maybe you are lucky enough to have a lake front property – adding in a dry river bed would be a way of uniting the lake and your garden. If you live in old Victorian home, it would be very difficult to create a Japanese style garden in front of it and make it look like they belong together. Take some time to reflect on the unique characteristics of your home and surroundings and draw you inspiration from them.

As we begin a new gardening season and start to work in our yards, take the opportunity to look at your garden in a new way and consider what changes you can make to create your own paradise. Remember, you never know what treasures are hidden in your own backyard until you begin to dig.
