Favourite blog/Vlog

One Yard Revolution - based in Chicago. He hasn't posted any new content in the past year, but his videos are great for learning about square foot gardening, raised beds, vermicompost, using locally available mulches, and small polytunnels. Comes with a cat!
Liz Zorab - Byther Farm - Welsh YouTuber with a good size garden that she uses for fruit, veg, and poultry. Great for its practicality - she talks openly about the challenges of maintaining a garden with a chronic health condition that means she prioritises functionality over appearance. A great vlog for anyone who gets fed up with the pristine gardens that you often see on social media!
Self Sufficient Me - an Australian YouTuber, but plenty of ideas and tips that are applicable anywhere. Very passionate about his subject. 
Charles Dowding - good for his no-dig approach and for seeing progress over the seasons. Often posts videos showing a particular crop from soil prep to harvest. 
Liziqi - less gardening and more stunningly beautiful rural Chinese (semi-fantasy) homesteading, with plenty of gardening elements. A bit hard to describe well, but worth a look. Very relaxing!
Huw Richards - very young professional YouTuber whom I find a bit annoying at times due to my own prejudices around public schoolboy types who present themselves authoritatively, even when they don't have much to back it up. However, he probably does have plenty to back it up with some good tips and a strong audience base.
