Excerpt From The Course
CYMBIDIUMS This is a very diverse group, with an immense number of hybrids and varieties. Cymbidiums are more cold tolerant than Cattleyas (they withstand temperatures to around 7 degrees Celsius); hence more are commonly grown in cooler areas. In cool areas many people have outstanding success with Cymbidiums grown in a shade house, on a veranda or under the protection of a large tree. Watering is ceased over winter, and in wet areas, some people turn pots on their side for a period to stop the roots getting too wet and rotting. Cymbidiums will perform better if winter temperatures can be kept around 10ºCelsius (perhaps bring them indoors over winter). Flower spikes develop over winter and bloom throughout the spring. Temperatures around 20‑27º Celsius are preferred over summer. All Cymbidiums prefer indirect sunlight, particularly once flowers open, however some are more sun tolerant than others. Pink or red Cymbidiums tolerate brighter light than green flowering types. Yellow and white flowering varieties vary in their light tolerance. Every variety of Cymbidium needs to reach a certain size before it will flower. This varies from one variety to the next: for one it may require three mature bulbs, and for another three times that number.Cymbidiums can be grown from back bulbs (pseudo bulbs), similar to the way Cattleyas are propagated, however with Cymbidiums, one pseudobulb is sufficient for a new plant. Bulb rot is common if pots get over wet in summer (control with a Fongarid drench). Black leaf spot often occurs ‑ control with a Mancozeb spray. If the summer is dry, bulb rot is unlikely, but mites are more likely. Watering in the evening in summer helps drop the root temperature for the night, which in turn helps initiate flowering. In very hot late summer conditions, apply a weak Epsom salts solution to Cymbidiums weekly. Feed Cymbidiums regularly over spring and autumn, but not through late summer – being short on nutrients in January/February, helps promote flowering. DENDROBIUMS There are several different groups of Dendrobiums: 1. Soft Cane ‑The cane is generally swollen or thick and soft inside. 2. Black Haired (Nigro‑hirsute) ‑canes are covered by short black hairs. 3. Hard Cane ‑canes are thin and long As a group, Dendrobiums are diverse both in how they look and how they need to be treated. Many are native to Australia while many others are exotic from Asia. Though most Dendrobiums are epiphytes and many need to be grown on a slab of fern or timber; some will grow quite well in a pot. There are Dendrobiums which will grow in all types of climates from the tropics to cool temperate areas, though most come from mild or warm climates. If we were to generalize the most important requirement is fresh air or good ventilation, followed by appropriate shade. Over watering is always a danger with Dendrobiums grown in pots. Many can be grown by division of offsets or separation. The pseudobulbs of Dendrobiums are commonly elongated and look like a piece of cane, hence are commonly called canes.

|D. kingianum||Hard cane||Semi‑shaded position||Pot or lithophyte|
|D. nobile||Soft cane||At least 50% shade||Epiphytic|
|D. speciosum||Hard cane||Prefers bright light||Epiphyte or (Sydney rock orchid) or lithophyte|
Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
How our courses work
- Choose Your Learning Method
You choose how you would like to receive your course material, i.e., Online, USB or Correspondence. The choice is yours. You may also work on online or offline.
- Tutor Allocation
Every student is assigned their own dedicated tutor who is an expert in their subject area. They provide as much or as little individual contact as you require. You can contact your tutor whenever you need – your hours are not limited.
- Feedback and Assignments
Tutor Feedback is an essential component in helping you understand the subject matter. Tutor feedback is given in the form of notes written on the assignment. We encourage you to contact your Tutor where help with clarification and understanding of course material may be required.
Your assignments are located at the end of each lesson. You submit them for marking whenever you are ready. There is no time limit.
- Set Tasks and Self-Tests
Most modules have a Set Task at the end of each lesson before for the assignment. This is where you get the opportunity to undertake practical work to help you acquire knowledge, skills and practical experience. Many modules also have short Self-Tests.
Once all assignments have been completed you may then elect to sit for a one and half hour exam in your own location. If you prefer not to take the exam you do have the option to undertake a project instead.
Once the exam or project part of the course is completed, your Certificate is then processed. Please allow approximately 4 weeks for this.
- Design Your Own Qualification
ADL offers students the flexibility to self-design their own qualification – bundling together a combination of 100-hour modules into a qualification higher than a certificate.
