LEARN TO PRUNE PLANTS - Understand How Plant Growth and Pruning are Linked. 

Become a "Certified Pruner"

 

Pruning is one of the fundamental skills needed by gardeners and horticulturalists. However, it is much more involved than merely cutting off plant growth. There are many different reasons to prune, and there are many different ways to go about pruning.

What to prune, when to prune, how to prune and why we prune - all these questions can be answered through this short course. For the professional horticulturist to the home gardener, understanding the science and technique of pruning will allow you to support and enhance the growth of plants and improve fruit and flower production.

This short course provides instruction on how to prune range of ornamental plants as well as important species like fruits and roses. Students will learn how to assess the pruning needs of plants and learn about good pruning practices. Furthermore, you’ll learn how to encourage fruiting and flowering, how to create topiary and espaliers, and how to make bonsai.  Upon completion you will feel confident in your knowledge of how and when to prune all sorts of plants.

LEARN HOW AND WHY TO WE PRUNE?

There are lots of different reasons and ways of pruning. Here are some:

Cleaning Out Dead Wood

It is important to remove dead tissue from your plants regularly. This will improve both their appearance and health. Infections (e.g. bacteria, fungal diseases and even insects) attack and gain a foothold in dead or weakened plant tissues with relative ease. Once established, they are able to multiply and spread much more easily into the healthy parts of the plants. Regular pruning can thus be a major way of controlling diseases in plants.

Any dead or rotting plant material still attached to a plant acts as a possible source of infection because it offers a weak point for entry of diseases. As such, it should be removed from the plant and removed form your garden. 
 

Stopping

Stopping (also known as tip-pruning or pinching) is a system of pruning that encourages bushy growth. As we've already seen, when a plant produces apical growth (known as apical dominance) it is because energy is concentrated in a single tip bud and the buds along the stem remain dormant. If the apical tip is removed the buds lower down will start to produce side-shoots. Some plants such as bedding plants usually only need to be tip pruned once whereas shrubby plants will produce very bushy growth and prolific blooms by repeated stopping. Stopping is also a way of diverting energy into fruit crops in plants such as grapes.  When doing this, you must think about how much growth you will be stimulating at the end of the branch.  You must not leave too much bare stem that will not only look unsightly, but which will not be able to support the flush of new growth.  

Disbudding 

This method of pruning involves removing the side or lateral buds as soon as they appear. This serves to focus energy in the terminal (top) bud. It reduces the amount of blooms allowing the remaining blooms to become larger and is a method that is particularly used for roses and camellias. 

This method is also used to prevent crowding of stems in plants such as chrysanthemums and to direct extra energy to root development.  You may also be doing it if you are growing tomatoes in a glasshouse.

Deadheading

Some plants drop their flowers while they’re still fresh whereas others hold on to the spent flowers for weeks, or even months. Deadheading, the action of cutting off dead flowers, is beneficial for garden plants for the following reasons:
 
When you cut off the dead flowers, you are cutting off dead tissue which could be harbouring diseases or attract pathogens.
The pruning cuts encourage side shoots to grow so the plant will produce more flowers.
You are removing unsightly withered flowers and improving the plant’s appearance.
By removing the flowers you are preventing seeds (and fruits) developing - so the plant has more energy for growth and further flower production.

Most flowering plants will benefit from deadheading including: annuals, herbaceous perennials, many flowering bulbs, roses, daisies (including their relatives such as dahlias and chrysanthemums), hydrangeas (leave the final flower heads through the winter months), azaleas, camellias and rhododendrons. The more frequent the deadheading the better because it encourages more flowers and can reduce the risk of disease.



Pollarding

Pollarding is a means of managing trees from an early age. It is carried out to obtain a short ornamental stem and maintain a small crown. The initial crown reduction forms a permanent framework. This is followed by regular (often annual) pruning. The main branches are cut back almost to the main trunk using secateurs or a sharp saw. Growth of thin, new branches is encouraged. Pollarding is commonly used in Europe to maintain the shape of street trees such as lime trees (Tilia species).

 

Who is this Course intended for?

  • Home gardeners who want to do a lot better in their gardens
  • Anyone starting up or wanting to expand the range of services offered in a garden business (e.g. a lawn mowing business, seeking to offer an expanded service. When mowing work declines in winter, you can have another source of income, pruning roses and fruit trees)
  • Anyone seeking employment as a gardener. This course can give you knowledge and skill that sets you apart and gives an employer a reason to consider you above other applicants
  • Garden managers seeking to train their staff
  • Gardeners, nurserymen, landscapers or horticulturists wanting to fill in a gap in their skills set.
