Become a Professional Gardener

We usually think of garden maintenance as a spring and summer priority when lawns, weeds and plants grow vigorously but even in fall and winter a garden may deteriorate without regular maintenance.

Plants that are fed well are healthier, resist disease and pest problems, and generally require less maintenance. If a plant is unhealthy, it may be because of a lack of good nutrition, but it can just as easily be because of something else. Healthy plants resist pest and disease problems.

Heat, cold, wind, rain, frost, shade, pollution and other environmental problems can have disastrous effects on plants. Plant varieties vary in their tolerance of these conditions, for example the heat which might kill one plant may simply slow the growth of another. Some plants are very adaptable others not. 

This course will show you how to create healthy gardens year round!

  • Learn to maintain plants and gardens
  • Build the skills needed to be an effective gardener
  • Increase your employability and opportunities for work in garden maintenance

Comment from a Student:

"All feedback from the tutor I had was very constructive and helpful.” David Painter, ACS student

"This is the first correspondence course I have done and I have thoroughly enjoyed it and I just wanted to say a big THANK YOU. I appreciate everyone's effort in such a professionally-run organisation with seamless administration. The office staff's happy can-do attitude, their fast responses to all queries, tutor Shane Gould's quick turnaround in assignment marking and his supportive and motivational feedback and last but not least, the sound subject guides. Most importantly I hope my thanks and appreciation can be communicated to all the staff who have supported me long the way of my learning! I work full time and study on the weekend but really don't stop thinking about what gardening solution I need in order to answer my assignments every day of the week. Thank you for such a great learning experience and I cant wait to start the second half of my course!!" Skye, ACS student

LEARN TO PRUNE PLANTS (and much more)

There are tens of thousands of different plants found in gardens; and they are all pruned differently. When you recognise this fact, you may think it is impossible to learn how to prune everything you might encounter in a garden; but when you properly understand the principles of pruning and how they can be applied to a range of different plant types -you then have a foundation for making sensible and appropriate decisions about pruning anything, anywhere.

The broad Principles of Pruning

Pruning involves cutting parts off a plant for one or several of the following reasons:

  • To remove dead or diseased wood which could affect other parts of the plant.
  • To exercise control over the type of growth which occurs. For example, to promote flowering, fruit or foliage, etc.
  • To control the size and/or shape of the plant.
  • To rejuvenate an old plant, replacing old wood with new wood.

IF YOU ARE NOT PRUNING FOR ONE OF THE ABOVE REASONS, THEN THERE IS NO REASON TO PRUNE AT ALL.

DON'T PRUNE JUST FOR THE SAKE OF PRUNING (Too many people do!)

The above things are achieved in different ways on different plants:

Removing Dead or Diseased Wood

  • Some plants are more susceptible to infection than others when you cut into their living tissue (e.g. Birch trees, some herbaceous plants). Such plants can find it difficult to contain wood rots once they start). Such plants need to have infected wood cut out and burnt before the disease spreads.
  • Always cut back into healthy, living tissue. Do not leave any diseased wood on a plant after
    pruning.
  • Make your cuts sharp and clean. Use sharp tools and don't tear or bruise plants. Use clean tools. If you prune diseased wood you may pick up disease spores which can then be transferred to healthy wood. It is a good idea to dip secateurs in an antiseptic when going from one plant to another.
  • No matter what you prune, or for what reason, you should always remove any dead or diseased wood.

Controlling the Type of Growth

  • There are three main types of plant growth: roots, vegetative top growth (ie. leaves and stems) and flowers/fruit. Discouraging one type of growth can help redirect the effort of the plant in the other types of growth.
  • Removing all flowers and fruit will usually stimulate vegetative growth.
  • Removing side shoots will generally cause a plant to grow taller more quickly.
  • Removing the growth tips will cause a plant to develop more side shoots and become more bushy.
  • Thinning out flowers and fruit will decrease the total number of flowers and fruit, but will usually improve the size and perhaps quality of those remaining fruit.
  • Cutting a plant back hard (if it can take it), will cause a flush of lush growth in the next growing season.
  • Cutting the roots of a plant, by plunging a spade into the soil or digging a trench, will force a flush of new growth in the roots closer to the base of the plant, for many plants, particularly those with fibrous root systems. This root pruning is used to either prepare a plant for transplanting, or to confine the roots from spreading into areas where they are not wanted). This treatment, however, can cause poor health or death in some plants, particularly if the cuts are made too close to the trunk of the plant.

Flower or Vegetative Buds?
Flower and vegetative buds can usually be told apart by their shape. Flower buds are plumper than vegetative (ie. leaf or stem) buds. Sometimes plants can also have mixed buds, where there are both flowers and shoots within the one bud. This occurs commonly in the terminal buds of the apple.
If you cut a bud open and look at it with a magnifying glass, you can usually see the premature leaves or flowers.

Controlling The Plants Shape and Size

  • It is important to remember that different plants have different levels of tolerance to hard cutting. With some plants, you can remove 50% of the foliage and improve vigour and health. With other types of plants, removing 50% of the foliage will commonly cause death.
  • Occasionally you will find a plant with low tolerance to hard pruning that will survive a hard prune. There are exceptions to the rule. You can state a plant's tolerance to cutting back as a percentage (e.g. Acacias can be cut back by up to 20%. This means that if more than 20% of the top growth is removed, the Acacia is likely to suffer).
  • If large branches are growing in a position where you do not want them, it is valid to remove them.
  • If foliage is spreading over a pathway, it is valid to cut that back.
  • Frequent light pruning is nearly always better for the plant than irregular heavy pruning.
  • If a branch that bears flowers and fruit hangs over a pool then removal of the branch may be
    Warranted. If a plant in a garden design is growing out of shape, then pruning to restore the initial design intention is recommended.

Rejuvenating A Plant

  • The lifespan of many plants is generally lengthened by regular pruning.
  • Removing old wood, while leaving in newer wood will rejuvenate most plants. Roses are typically pruned this way in temperate climates over a period of years, the younger growth emerging from the base of the plant are left if strong, while the older woody stems are cut out. The lifespan of a rose is increased greatly by this method.
  • Many annuals can be rejuvenated and given a second or third life at flowering due to pruning.
  • An old vigorously growing plant that has become too large can be refreshed and reshaped by rejuvenating pruning.

Start by Learning to Apply these Principles to specific plants such as roses, trees, flowering shrubs and fruit trees.
