Azaleas & Rhododendrons

  Develop a broadened knowledge of Azaleas & Rhododendrons, their cultivars and cultivation.   Azaleas and Rhododendrons are actually in the same botanical category (i.e. genus Rhododendron).  Azalea is a common name used to describe many smaller growing shrubs from the genus Rhododendron.  Broadly speaking, azaleas have both smaller leaves, and generally a lesser height. Considered by many to be the very best plants a garden can offer, azaleas and rhododendrons are some of the most popular plants grown anywhere. The course shows how to grow them to perfection, and builds your knowledge of varieties available, to give you a long lasting display of colour in the garden. Soils, weed control, feeding, pest and disease control, watering, landscape design and lots more are included over eight lessons.

Greenhouse Cut Flowers

  A course for commercial cut flower growers who are concerned exclusively with greenhouse production. International trade in cut flowers has grown over recent decades. In most countries, developed or in development, it is now possible to get the most popular types of cut flowers almost any time of the year. The industry has made this possible by doing three different things: 1. Expanding trade between countries (e.g. Australian tulips might be flown to the Netherlands in August and September, when they are not flowering in The Netherlands; and Dutch tulips might be flown to Australia when it is autumn in Australia) 2. Breeding new varieties has extended the flowering season for some plants. It is now, for instance, possible to grow Chrysanthemum varieties that flower all year round in some climates. 3. Growing in greenhouses has enabled farmers to take control of conditions that stimulate flowering; and cause plants to not only grow faster, but also flower at times when they might not have otherwise flowered.

Growing Annuals

  Become an expert with Herbaceous Annual Flowering Plants. Learn to identify and cultivate annual flowers, for bedding displays, potted colour or cut flowers. Annuals are a valuable horticultural crop grown commercially as cut flowers, as seedlings or as advanced pots of colour.  With careful choice,  versatile annuals can deliver year round colour in the home garden. They work to fill gaps between perennials, they can be used to disguise the messy foliage of bulbs as they seasonally die-off,  and they can help to keep gardens or parks in the peak of perfection. This eight lesson course reveals the secrets of how to identify annual species,  what to grow and when to grow each variety. It covers soil improvement,  pest control, irrigation, propagation, greenhouse growing, hydroponics and much more. It is equally as useful to the home gardener and to the professional gardener as to those intending to grow annuals commercially.

Growing Camellias

  Camellias are a hardy group of plants that are grown from cool temperate climates through to tropical regions. While many Camellia species are highly adaptable, the best results are generally achieved by choosing cultivars to suit the climate and conditions you are growing them in. Tea leaves are derived from the plant Camellia sinensis, a species that does well in tropical and sub tropical conditions. Other species, (eg. Camellia reticulata) does not adapt so well to warm climates, and is generally far better in a cool temperate climate. Camellia oleifera is another species grown as a commercial crop oil from this species is used commercially in china. The three most common ornamental species are: Camellia japonica mainly bred varieties from the original, smaller flowered species. Camellia sasanqua species from Japan, smaller flowers than C. japonica. Camellia reticulata species from China.

Growing Grevilleas

  Develop your ability to select and cultivate appropriate varieties of Grevilleas in different situations. Grevilleas are a wide group of plants, all but seven species coming from Australia. They are widespread across Australia, occurring in both cool temperate, and hot tropical climates. There are around 250 species. About half of these are native to the south west corner of Australia. Known commonly as “Spider Flowers”; the Grevillea flower is more like a brush than a traditional flower. It has obscure petals, but is none the less very colourful. Flower colour varies greatly; and most hold their flowers for a long period. Grevilleas include both small to very large plants (from prostrate ground covers, through small and medium shrubs up to large trees). Their hardiness is variable according to species. The foliage is also variable ranging from small, entire leaves to lobed or pinnate leaves. All are arranged alternately on the stems and some have hairy undersurfaces.  Most have a medium to fast growth rate. “There are so many of these wonderful colourful plants in our gardens today. Not only are they striking to look at, they also attract birdlife. It really is worth getting to know them a little bit better.”- Tracey Morris Dip.Hort., Cert.Hort., Cert III Organic Farming.

Roses

  For the rose enthusiast - this unique and comprehensive course is equally relevant to professional and amateur growers. Roses, often referred to as 'The Queen of the Garden', are one of the most popular and prized ornamental plants. They are included in the greatest gardens in the world  and many claim roses to be the most beautiful flower in existence. The  value of their blooms however extends beyond the ornamental garden; roses are grown for many reasons including: the cut flower trade, for perfume extraction, to harvest the hips and for rose oil. This course covers all these aspects and much more. Learn the history of the rose, the confusing rose classification system, how to identify the different species, their general cultural needs (soils, pests and disease management and pruning), how to use roses in garden design and how to produce a commercial rose crop.
