What to expect:

The citrus genus varies widely in respect to the variety of species and fruit types within it, popular ones being cumquats, limes, lemons, oranges, mandarins and less common fruits like buddha’s hand, pomelos, finger limes and the japanese yuzu. They earn their place in your backyard with divine white scented blooms and winter fruits that help combat colds with their high Vitamin C content. The distinctive glossy green foliage and attractive fragrances of leaves, fruit and flowers add to the charm and make citrus highly sought after and widely grown by both commercial producers and enthusiasts.

How does it work?

At the end of each lesson, you will be given a short interactive test to undertake, which will provide an indication of how your learning is progressing. Upon completing the very last lesson, you will be offered a more thorough automated test or examination. This final assessment can be undertaken at any time of day or night; and any day of the week; and if you achieve an overall pass (60% or more); you will be able to obtain a “certificate of completion” with your name and completion date on it.

Note: these short courses are self-guided online courses and are not to be confused with our tutor-supported online courses.
