Become an Expert at Garden Restoration

Learn to survey, analyse and plan sensitive and appropriate renovation of established gardens, generally of 2 hectares or less in size.

Restoring old gardens to their former glory is a lot more involved than what most people would realise.

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.

How to Restore Stone or Brick Walls

The techniques and materials used for cleaning brick and stone walls and also for repairing and sealing are the same.
Major problems are:
  • Severe weathering
  • Salt laden air
  • Stress cracks – usually in the mortar but sometimes the stone or brick
  • Efflorescence i.e. salts in the stone dry out and leaves a fine grained crystalline deposit of the surface
  • Pollution – deposits of oil, soot or mineral residue
  • Environmental – Fungus, moss and mildew

1. Stress cracks – chisel out loose mortar and re-apply new mortar into the effected joints making sure to recess each joint slightly
OR for cracked stone or bricks chisel out all surrounding mortar then remove broken piece using a coal chisel and hammer. Insert new piece and re-mortar the surrounding area (ensure a solid fit).

2. Salt Air – sealants are the best way to prevent damage from salt laden air or severe weathering and efflorescence
Applying a sealer can minimize brick or stone damage from salt air and severe weathering. It can even work to prevent efflorescence. However, just as with concrete, brick and stone should be thoroughly cleaned before applying a sealer. 

3. Fungus, moss and mildew are best removed by firstly scraping off as much as possible with a wire brush or putty knife, then using household bleach/water with a 1:4 ratio apply with a stiff bristle brush, leave to penetrate and then rinse with fresh water

4. Oil, soot and mineral residue usually penetrate deeper into the surface of the stone or bricks. Use a solution of 1:9 muriatic acid to water. Apply solution and leave for 15minutes then clean the area using a stiff bristled brush and rinse with fresh water,

5. Remove old paint by sandblasting, chemical paint remover, muriatic acid or a commercial power washer

Re-pointing
As masonry work ages it may need re-pointing from time to time – remove the dried patches and replace with new mortar. The only problem with this is that the new mortar will show up against the old. Colour matched latex paint can be used to overcome this problem – applied with a small artist’s brush.

NOTE:

  • Wire brushes can damage some stone surfaces
  • Wall surfaces will look better if cleaned regularly rather then once the damage is done
  • Ensure that water does not pool at the base of a wall
  • Allow air and sun to reach the wall surface as much as possible to prevent growth of moss and lichen
 

WHO COULD BENEFIT FROM THIS COURSE?

Gardens don't stay the same. They are living things; that get affected over time by the environment, plants, pests, weeds, decaying materials and more. If maintenance is regular and routine, they may change but not decline. All too often though; the maintenance is not always what it should be, and gardens do decline.

At some point though; ownership of gardens will change; or the fortunes of an owner will change. As a result, there will come a point when the owners of any neglected, an old garden will be faced with the prospect of either destroying or restoring the garden

This is the Point at which Opportunities Arise for Landscapers

Restoring an old garden is not the same as constructing a new one; particularly if there is a desire to remain true to the original design.

As the years roll on, and more gardens become older; the need for garden renovators grows.  This is an area of landscaping that offers increasing opportunity to those who know how to do the job, and do it properly. The clients are often people with money and motivation to do things which the average landscape client might not be wanting to do.

If you are a landscape professional (or aspiring landscaper), with a desire to set yourself apart from your competitors, this course is a very good way of doing just that.

Garden renovation is a specialised area of landscaping; not commonly understood by the average landscape professional -but if you want to learn it, here is your opportunity.
