Learn to identify and grow a wide range of plants and understand the science that underpins horticulture. This advanced horticultural course is ideal for gardeners, landscapers, horticulturalists or those who work in garden centres or retail nurseries.
The Certificate of Horticulture (Advanced) is an online professional development program that follows on from the Certificate of Horticulture and shows you how to identify a wide range of plants systematically and scientifically to maximise their care and prolong their growth cycle.
In this online horticulture course, you will study groups of plants, herbs, vegetables, fruit, berries, nuts, and indigenous, ornamental, tropical, indoor and bedding plants.
On completion of this course, you’ll have a strong foundation in horticulture to pursue a lifelong career.
