Study Ferns and become a better Plantsman

  • Start anytime, study at your own pace
  • Learn from a team of expert horticulturists, led by John Mason; author of Growing Ferns (published by Kangaroo Press)

We think of ferns as shade loving plants that need damp conditions; and many are.
There are however ferns that grow in all sorts of conditions, from extremely hot to very cold. Some grow just as well in the full sun, as others do in very heavy shade; and some will even survive extended periods of drought.

You can grow ferns as an indoor plants; in woodland or water gardens, in areas that are difficult to drain or prone to flooding, or as container plants in a shadehouse or fernery.  

Lesson Structure

There are 8 lessons in this course:

  1. Introduction
    • Review of the system of plant identification, general characteristics of the ferns (especially the fronds), main groups of ferns (filmy, tree, terrestrial, epiphytic and water ferns), information contacts (ie: nurseries, seed, clubs, etc.), pronunciation of plant names.
  2. Culture
    • How best to grow ferns and what conditions do they need. Planting, mulching, watering, pest & disease and their control, feeding, pruning, protection from wind, salt air, etc., compost making.
  3. Propagation
    • Methods of propagating ferns - spores, division, tissue culture. Propagation of selected varieties.
  4. The Most Commonly Grown Varieties.
    • Maidenhairs, tree ferns, stags, elks, common ground ferns. How to grow and propagate these ferns.
  5. Other Important Groups.
    • Asplenium, Blechnum, Nephrolepis, Pteris and other groups. Group characteristics, cultural details, propagation methods.
  6. Other Varieties
    • Hares foot fern, Bracken, Fans, Corals and Combs.
  7. Making the best use of these Plants.
    • In containers, hanging baskets, terrariums, in the ground, as indoor plants, growing and showing, growing for profit (to sell the plants or what they produce).
  8. Special Assignment - Detailed culture and identification of one genera.

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

Why Grow Ferns?

Flowering plants often look great when they flower, but not so good at other times of the year. Ferns on the other hand, have the potential to look stunning, all year round: if you grow the appropriate cultivar and treat it well.  This course will teach you to do just that.

Ferns are plants which are of unusual shape and growth habit which make them particularly interesting to study.

To most people ferns are very graceful and lush and invoke an image of coolness, calmness and peacefulness. Though lacking flowers they have enormous variety in plant size and form and in the texture, shape and color of the fronds. Ferns are very adaptable and can be grown in a wide variety of situations. While most prefer moist, shaded conditions there are ferns that are suited to open sunny positions, growing naturally in rocky crevices, exposed coastal cliffs, high on living tree trunks or on fallen trees, in alpine bogs, even in semi arid areas. Some species of ferns are tiny with fronds only one cell thick, others can reach a height of 15 metres or more. Some ferns will spread to form huge colonies, while others will grow like climbers.

Initially ferns need water during their early development from spore to full adult plant. But once growing in the soil, some ferns are very hardy. Different ferns tolerate different climatic extremes, especially considering they have been around since the beginning of time. Some can survive prolonged drought in semi-desert conditions and others are adapted to surviving under feet of snow.

They are great indicators of the natural balance in their environment. Growing only when the conditions are right to their preferable niche. They are often used in environmental surveys of flora as a measurement of the environments condition. If the native species for that area are not surviving, then it is an indication things are out of balance.

It is a real treat to find small pockets of ferns in areas you would not expect and to find much rarer species than you thought could be available. So go searching!

Ferns Occur in Most Countries and Climates, World wide

The world’s climate varies from place to place considerably! As such there are many variations in ferns. Often from once district to another they may vary slightly due to environmental conditions, yet it is impossible to simplify these variations.

The gardener must, of necessity, rely heavily on common sense in applying what is read from this, or any other book, to their own situation.

Ferns are widely distributed in the well watered zones of the world. They are much less common in the very dry (central Africa and Central Australia) or severely cold regions (Antarctica, arctic). They are well developed in the temperate zone (woodlands, open forests) and often the dominant component of the vegetation in tropical regions. More species are found in rain forest habitats than anywhere else on earth. This includes lowland jungles, mountain forests, even the forests of high altitudes. They can be found from the coast to inland and can be found at altitudes of over 3,500 metres (11,500 feet)! For example, the mountains of Peru, and the Himalayas.

Hardy ferns that grow in semi-arid and arid climates overcome the worst of dry climates by water conserving strategies (fronds small and covered in hairs to reduce water loss, or fronds may curl in dry periods to conserve water loss). Some ferns have even adapted to mangrove environments (The Mangrove Fern, Acrostichum speciosum), There are also several aquatic (water dwelling) ferns including Azolla, Nardoo and Salvinia.

The huge diversity in ferns has allowed them to adapt to almost every environmental biome on earth and there are at least 10,000 species of ferns throughout the world.

Some ferns (eg. Bracken) occurs on most continents; while others occur only in certain countries or regions. Eg. Australia has around 450, belonging to at least 118 genera. More than 300 species are native to Queensland, around 170 in N.S.W., 120 in Victoria, 95 in Tasmania, 50 in South Australia and 65 in Western Australia.

 

Ferns are living things and as such are somewhat unpredictable & variable.

When you refer to a book or magazine article, always look at where it was written and who it was written by (for example: A gardening writer from London, UK; may usually talk about gardening in the UK. If you are from Los Angeles or Sydney, these recommendations may be quite misleading for you!). There can be great variations over relatively small distances in such things as rainfall, wind and soil type. A certain type of tree might very well grow twice as tall in the eastern suburbs of Melbourne as it will grow in the Western suburbs of the same city.

With plant culture there are always different, equally valid ways of tackling any job. Never think that a particular technique is the only way of doing something! You should try to be aware of the advantages and disadvantages of all of the alternatives. It is up to your own preferences as to which way you choose to do something.

This course has been written to teach you about growing ferns in a way which will be relevant to any place (in the world). It puts aside regional techniques and tries to teach you principles and concepts which can be applied to anywhere. Keep this in mind as you study; try to see the principles; not just black and white facts.

 

Horticulture deals with living things and as such is somewhat unpredictable and variable. The ways you treat a plant is different from place to place, time to time and according to what you are trying to get from the plant.

When referring to a book or magazine article, always look at where it was written and who it was written by. The information contained in the article can be very location specific – an author talking about gardening in Switzerland will offer different information to someone in Australia, for example. There can also be great variations over relatively small distances in such things as rainfall, wind and soil type.

When growing ferns there are different ways of tackling any job; often each one just as correct as the other. Never consider that a particular technique is the only way of doing something! You should try to be aware of the advantages and disadvantages of all of the alternatives. They all have their pros and cons....and it is up to your own preferences as to which way you choose to do something.
