Fruit Tree Ebb and Flow
I am planning on setting up a bucket ebb and flow system to grow dwarf fruit trees. The containers will be two buckets stacked on top of each other, with the inside bucket having holes drilled in it. So for example a 3.6 gallon inside of a 5 gallon. My question is what size buckets would be the best for growing the trees in? I really don't want to mess with root care, so a bucket large enough to not have to repot would be great. However that being said I will root prune if its the best way. Also what type of medium would be best? Right now I have tons of Hydroton, but would perlite or gravel be better?
