Horticulture -The Basics
Learn About Horticulture - The Basics
Understanding our plants and how their relationship to their location, growing practices and the environment is an area which brings huge joy to horticulturalists, gardeners and botanists, whether they are growing plants for personal or commercial use.
This course has been designed to give you a good introduction to many of the principles of good horticultural practice. You will learn, or add to your existing knowledge about plants, how they work, why they do well, or not in some cases.
You will be able to understand and relate to your site, the plants you can effectively grow there and really get to know about horticulture as a subject.
Whether you are looking to expand your knowledge so you can work more effectively in your own site, or obtain a good overview of the subject before deciding which areas you would like to study further, this course will provide a great introduction, whilst also challenging and pushing you to find out more should you wish.
Horticulture – The Basics, includes the study of:
- plant physiology.
- how to grow and maintain types of plants,
- provide the best environment for them,
- their affect on the environment and
- commercial importance of certain practices.
- protecting plants from pests and diseases,
- regulation and control of plants commercially and privately,
- naming, plant breeder’s rights
- covers some areas of botany with a wider scope.
Horticulture is not botany. Horticulture is more about the relationship between us and plants – the growing of them.
