Become an Expert with Geraniums and Pelargoniums

  • Learn to Grow and Identify Pelargoniums and Geraniums  
  • Course developed by John Mason (author of Hyland House book -Growing Pelargoniums and Geraniums) with experts from Australia and the UK.
  • Indulge a passion or enhance a career

Geraniums and Pelargoniums are great collector’s plants with many varieties available. They are a good source of vivid colour, even in winter if a warm situation is provided.
This course opens up a wealth of possibilities for growing and using these plants.

 

Hybrids

Gardeners today are spoiled for choice, with more types of geraniums and pelargoniums to choose from, than ever before.

Many of today's cultivars come from many years of hybridization between species -cross pollination and breeding that began in the 17th and 18th centuries. Nursery people were deeply impressed by these plants and public interest increased again after World War II with more hybridizing. A lot of progress has been made since the early days; with today's gardeners having an outstanding range of cultivars to choose from.

Three hundred years ago in England the scented - leaved geraniums were used for sweetening the damp rooms of cottages, and they will refresh modern day homes in the same way asking very little in return. So much so they could be classed as a flower for 'everyone' as everyone can grow them and use them in landscaping. The red geranium was the favorite flower of Charles Dickens, Henry Lawson wrote a short story called 'Water Them Geraniums', and now in the 20th century they can be grown as a courtyard pot plant, fed and pampered, or left without much attention they will still struggle to flower and give cheer. 

Geraniums have for a long time been grown by gardeners who have considered them as an easy and as a 'forget them' type of plant. Even with little care they still produce a floral display. They are frequently used as a 'for-now' plant to fill in an awkward spot until something else can be chosen to be placed there, or until something slower growing can grow to fill the surrounding space.

There are geraniums suitable for borders and small corners, some are suitable for rockeries, hedges and hanging baskets. Large urns, window boxes and retainer walls are decorated (and hidden) by the cascading 'ivy' forms of geraniums. An open garden of regal geraniums provides a splash of colour with smaller growing deacons at their bases. The cut flower industry regularly uses geranium flowers for posies and the foliage for arrangements.

 

Opportunities

  • Start your own pelargonium or geranium nursery business
  • Expand your plant knowledge as a gardener, garden designer, plantsman

Aims

  • To develop your ability to select and cultivate appropriate varieties of geraniums and pelargoniums in different situations.
  • To describe the cultural requirements of various Geranium and Pelargoniums. Cultural requirements refer to the aspects that affect the growing quality and performance of the species. This includes soil types, plant nutrition, planting techniques, watering and maintenance.
  • Every variety of plant has its own specific needs and tolerances with respect to the environment in which it grows.
  • Learn about the options for propagating Geranium and Pelargoniums. There are specific ways they can be propagated, often with much ease to the home gardener. This is part of the reason they have become so popular, as they are so easy to grow and love.
  • Determine and explain a variety of ways Geranium and Pelargoniums may be used both in landscape and other situations.
  • Most Zonal Pelargonium is used for bright displays in the dullest of places with their vibrant flowers offering a show. Most Ivy Geraniums are used to spill over walls, hanging baskets or climbing a brick wall on a trellis. The options are limitless and we will look at a few.
  • To become aware of the various disease problems that affect Pelargonium and Geraniums. Also learn ways to manage pest problems on pelargonium and geraniums. Geraniums, like all plants, can be attacked by pests or diseases, or can suffer as a result of poor environmental conditions, or from a combination of both of these. Unlike humans plants cannot develop an immunity towards disease. The best defence against problems, therefore, is to keep your plants as healthy as possible so that firstly they are more likely to resist such problems, and secondly, if they do suffer problems, to have a better chance of recovery.
  • Understand and manage water requirements of geraniums and pelargoniums, in a way to optimize the plant’s performance.
  • Manage the growing of Pelargoniums and Geraniums in a greenhouse. This can be adapted for climates that are too cool for them to grow outside or for areas where they need protection form frosts or other environmental conditions. This is aimed at commercial production but can be adapted by the home gardener too.
  • Learn how to plan the establishment of a collection of different cultivars of a group of geraniums or pelargoniums
