Ornamental Plants

Ornamental Plants are the backbone of garden maintenance, landscaping, parks management and nursery management. There is a system to the way plants are both classified, and also how they are treated.
If you can learn to identify characteristics which are common to different plant families, you will have a basis upon which to identify any unknown plant.
In a very general sense, plants within the same family also tend to share similar cultural requirements as well; so when you can place a plant in a particular familiy, you can often also determine how to treat it

WHAT TO PLANT WHERE

Just about every gardener, has come across a place in their garden where plants are difficult to grow. For some gardeners this could be their entire garden! There are many reasons why this might occur, with most resulting from a combination of local climate and soil conditions. Some common problems include:

 

· Alkaline soils – these are soils with a pH greater than 7.

· Waterlogged soils – where drainage is poor, generally due to the site being in a low lying area, or because of poorly structured soils, such as heavy clays.

· Salinity – a problem in many parts of Australia, not just in agricultural areas, but increasingly in urban fringe areas.

· Strong winds, poor soils and salty conditions associated with coastal areas.

· Windy areas.

· Hot, dry areas.

 

How To Cope With Problem Areas

There are two main ways to overcome such problem areas in the garden. These are to:

  • Modify local conditions to better suit the plants you wish to grow, such as providing irrigation in hot, dry areas; or growing or building a windbreak in windy areas, improving drainage, or lowering soil pH in alkaline soils. Such remedies can often be very difficult to achieve, time consuming, or expensive.
  • Grow plants which suit, or will cope with the conditions present in your garden. If you choose your plants carefully you can often have a garden that is very rewarding in terms of its appearance, and its hardiness.
