Home Studies Course -Training Program to landscape the Restored Garden

If a restoration is to be credible, the landscaper needs to understand the history and determine what is authentic and appropriate for a restoration; before they even start to plan the work that needs to be undertaken.

Despite the complexities and costs involved; there is an ever increasing demand for garden renovation specialists. If you love both gardens and history; this could be an ideal career move for you.

Critical aspects of garden restoration are to:

  • Determine what existing plants and features to retain
  • What new plants to introduce
  • What new or replacement features to include

To make these decisions, you need to consider

  • What plants are growing on the site
  • Which of the current plants were in the original design; and whether any were not originally intended to be in the garden
  • What did the original planting design intend; and is that intent still valid and viable
  • What features are still present from the original design (eg.  paths, paving, walls, fencing, water features, sculpture, etc)
  • What features are partly or completely absent (evidence may still exist of their original presence)
  • What hard landscape features need attention; and how they might be attended to while still maintaining integrity of the design.

Aims

  • Discuss the history of UK garden design and the influence of plant introductions.
  • Evaluate an established ornamental garden in order to determine any particular design style period, or plants of interest.
  • Describe basic methods for the survey and recording of the layout and content of an established garden, and explain the importance of detailed information including assessment of site factors.
  • Explain processes and the need for assessment and recording of the type, condition and future potential of a range of plantings and features in an ornamental garden.
  • Explain the main criteria used to select plantings and features for retention in a restored garden.
  • Explain the need and processes of analysis of collected information.
  • Prepare a summarised programme for organisation of garden restoration work
  • Assess risk and identify safe work practices
  • Recognise and explain the visible signs of the failure of old land drainage systems and describe remedial measures
  • Describe and explain the practical procedures necessary for the restoration of a range of hard landscape features.
  • Explain problems which may be encountered in the improvement of retained hedges, plantings and lawns.
  • Describe practical solutions for improving retained hedges, plantings and lawns
  • Evaluate the use of modern maintenance techniques in established gardens

When you renovate an old garden you have the advantage that most of the broad structure is in place. Renovation is easier and cheaper than starting from scratch.  Some components may need cleaning, repairing, replacing or maybe even altering, but there is usually a lot that can be used. That means a garden renovation can provide quicker results than a totally new garden construction on a bare area of land.

What Should be Restored?
In any garden restoration project; there will be components that can be left as is; other components that can be restored, and other things that simply must be replaced (or removed).

Having assessed a garden properly, you have a basis for making these decisions.

Why Keep Something?
• Because it is in good (or at least acceptable) condition.
• Because it contributes to the integrity of the total design
• Because it is sustainable (It is not going to continue degrading)

• It is integral (ie. It supports/affects or integrates with other components). To remove it would create negative impacts.

Why Discard Something?
• It is beyond salvage
• It is too costly to maintain (Resources are not available to ensure it is maintained)
• It was introduced after the original development; and does not contribute to the garden in any significant way.

 

WHO BENEFITS FROM THIS COURSE

  • It is a valuable study program for even those who have worked in landscaping for some time, but who seek a deeper and broader knowledge of garden renovation.
  • This course has been developed by professionals in both Australia and the UK, with the aim of being relevant throughout the world
