Course CodeBHT347Fee CodeS3Duration (approx)100 hoursQualificationStatement of Attainment Learn all about Woody Flowering Shrubs. Build your plant knowledge and grow you plant expertise to the next level. This course provides a sound framework for understanding, identifying and deciding the best way to grow and use shrubs: all based on the taxonomic framework of plant orders and families used by scientists and professional horticulturists.. Shrubs, and trees if present, are the backbone of any garden. They provide the structure or framework that acts as a backdrop for other plants like bulbs, annuals, climbers, and groundcovers. For the most part, shrubs are more permanent plantings than many other plants, therefore it is vital to prepare the soil properly before planting. Once established, mature shrubs can provide privacy from neighbours, beauty against a tired fence, and many other advantages that give a space charm and elegance.

Describe different techniques used to prepare for planting, plant, nurture and maintain shrubs in different horticultural situations. Identify and describe a variety of different commonly grown flowering shrubs that are related to roses, in that they are on occasion classified into the taxonomic order Rosales or the superorder Rosanae. Identify and describe a variety of different commonly grown flowering shrubs that are related to lavender, in that they are on occasion classified into the taxonomic superorder Asteranae. Identify and describe a variety of different commonly grown flowering shrubs that are related to rhododendrons, in that they are on occasion classified into the taxonomic order Ericales. Identify and describe a variety of different commonly grown flowering shrubs that are related to Leptospermums, in that they are on occasion classified into the taxonomic order Rosales or the superorder Myrtiflorae. Identify and describe a variety of different commonly grown flowering shrubs that are related to Viburnum and Cestrum, in that they are on occasion classified into the taxonomic groups Corniflorae and Solaniflorae. Identify and describe a variety of different commonly grown flowering shrubs that are from significant plant families not studied earlier in this course. Select appropriate shrubs and explain how to use them in different places. Who might benefit from this course?
