Gardening is a wonderful hobby that offers many benefits, from enhancing your outdoor space’s beauty to providing fresh produce to enjoy. However, like any new endeavour, gardening comes with its own terminology that can overwhelm beginners.
In this module, we will explore the top gardening terminology you’ll need to know to give you the confidence to start your gardening journey. We’ll cover the basic terms relating to plants, soil, and gardening tools, which will help you understand the fundamental concepts of gardening. By the end of this lesson, you’ll have a good grasp of the essential terminology and be well on your way to becoming a more confident and knowledgeable gardener.

Gardening Quiz
Before we take a look at some basic terms, we thought you might want to test your knowledge with a quick quiz that includes some common gardening terms – this is just for fun and provides a good benchmark that you can use to measure your progress at the end of the course. We don’t expect any beginner to get a perfect score, so don’t worry if you struggle to answer some questions; give them your best guess.
Loading…Your quiz is done - how did you get on? We mixed up the questions, so some are hard if you don't know much about gardening. As you work your way through this course, you'll come across plenty of gardening terms. The next step is to get your head around a few before our next lesson.

Garden terminology finder
At the start of the course, we thought it best to include a tool that will help introduce you to some key garden terminology. We'll keep updating with more terms, so you may want to keep this page bookmarked and refer back to it in the future. Feel free to browse through the terms by selecting the various letters.
