CIT Horticulture Scholarship

Open gardens Canberra also sponsors an annual Horticulture scholarship. The Open Gardens Canberra Scholarship provides an exciting opportunity for a CIT student in any horticulture stream to receive financial assistance with their studies. Eligible students are in their first year of a CIT qualification in horticulture or landscaping, within the CIT Department of Horticulture and Floristry. The Open Gardens Canberra Scholarship provides $2,000 over two years towards CIT tuition fees, textbooks and equipment.
