Improving Gardening Skills

My name is Jaime and I am a garden lover. My question to you is do you know of a course that I can take to improve my gardening skills for plants, herbs and vegetables?

You do not indicate where you are located, but in North America, it is now possible to take gardening courses from community adult education programs offered by schools and colleges. In our area, for instance, Durham College and Durham Region high schools offer courses.
Check with your local horticultural society for suggestions about what courses to take.
