FERNS BHT314

CONTENT

Emphasis is placed on the horticulturally valuable species. The content of each of the eight lessons is as outlined below:

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.

• Prepare a collection of fifty ferns, not collected elsewhere, including:
  • a photo, drawing or pressed specimen *plant names (scientific and common)
  • cultural details
  • uses/applications
• Develop guidelines for growing ferns either indoors, in containers under shade, or in the ground.
  
• Label a sequence of four drawings which illustrate the propagation of ferns by spore.
  
• List different fern genera that can be propagated by division.
  
• Propagate four fern species, using two different methods, including spores and division.
  
• Explain the planting requirements of ferns.
  
• List the preferred characteristics of a soil which is to grow ferns in the your locality.
  
• Prepare a potting media mix suitable for growing ferns in.
  
• Develop guidelines for watering a typical fernery in your locality for a twelve month period.
  
• Write a summary of nutrition requirements of ferns, including fertiliser recommendations.
  
• Explain different common health problems of ferns.
  
• List guidelines for pruning ferns in your locality.
  
• Write a set of guidelines for the culture of a selected fern genus, including details on:
  • distinguishing between different species
  • cultural requirements
  • uses/applications
• Prepare a table which compares twenty-five different commonly grown fern genera, and includes:
  • plant description
  • preferred habitat
  • growing requirements
  • uses
• List methods used to propagate different ferns, including four different propagation methods.
  
• Write an essay comparing different species of ferns in the one genera, with reference to physical appearance, growth habit and cultural requirements.
  
• Describe endemic growing conditions of five different native ferns sited in natural areas.
  
• Prepare a schedule of cultural tasks to be undertaken over a twelve month period which are highly specific to one nominated species of fern.
  
• Summarise, a procedure for maintenance over a twelve month period, of a Nephrolepis grown in hanging baskets, including comments on:
  • feeding
  • watering
  • pest control
  • pruning
  • potting up
• List ten fern species, from at least five different genera, which are particularly suited to growing in hanging baskets in your locality.
  
• Compare the suitability of different types of hanging baskets for growing ferns, including:
  • water wells

• List twenty fern species which grow in very wet conditions, including aquatic plants and bog plants.
  
• Distinguish between the cultural requirements of ferns grown indoors and outdoors.
  
• Explain the cultural techniques which are unique to growing ferns as an epiphyte. Gow a fern using a specialised technique (eg. in a terrarium or hanging basket), monitoring it over 3 months (ie. recording cultural practices, changes in health, and performance).
  
• Write guidelines for preparation of a potted fern for competition in a garden show.
  
• Evaluate the use of ferns in a garden, which incorporates both ferns and flowering plants, using a supplied checklist of design criteria.
  
• Evaluate the use of ferns in a garden or interior plantscape, which is either all or predominantly ferns, using a supplied checklist of design criteria.
  
• Design a fern garden bed of 30 square meters, which incorporates at least ten different fern varieties, and satisfies both aesthetic and cultural requirements of a specified site, which you survey.
