I have ditched network television shows (for the most part) and YouTube is my go to place to watch TV when I have time to YouTube & chill. Expanding my knowledge in whatever topic I desire. The key to finding the best channel for you is look for someone you enjoy listening to and watching. Not all video skills are the same...mine included. Also, finding a YouTuber in your area can be helpful so that you can follow their planting schedules & varieties they harvest!
Here is my list of favorite gardening YouTube channels to subscribe to:
