There are plenty of videos you can make in a limited number of gardens; you just need to think about it differently and think outside the box at times.
cheese n spice you have aged...lol only kidding. thanx fpor the mention, I guess there are two trains of thought, are you doing youtube for yourself or everyone else? a lot of youtube now, is "click baity" you have to have a catchy title and thumbnail, intros are out outros are in, personally I like a good debatable chatty video, something I can oppose too, lol, I like progression videos, like LHL where you can see things moving forward,
Way too many youtubers overdo production and editing. Simple vlog is fine, content is what most want to see. Make it easy on yourself and more content is way to go.
