>>1460637Seems libgen has it and at least a couple of the mirrors work,
http://booksdescr.org/item/index.php?md5=AFB0A4ABF40AE578D2617F61D1270A32I think the main problem with dwarfing trees is their vigor. While you can bonsai a tree, that method uses root pruning to help stunt the vigor of the plant. Vigor for this type of endeavour is the main enemy. Many dwarf fruit trees are grafted to the root stock of trees that have low vigor. This helps maintain ultra-dwarf, dwarf or semi-dwarf sizes. It isn't a silver bullet and there's still a ton of pruning going on, it just helps a lot. This way of reducing vigor also reduces lifespan. All this is also mentioned in the book, fyi. If you are going to get grafted trees, get ones that are ultra-dwarf or dwarf. There's no reason to get semi-dwarf for what you want to do. Just remember that the shorter lifespan means you'll need to get more trees and overlap their life cycles so when the first batch die, the second batch are already fruiting well.
I made the mistake of growing fruit trees from seed and expecting them to be easily managed for espalier. Oh, it can be done, I just didn't expect 3 feet of growth in 2 months/6-8 feet during the entire growing season. lol
As for the book, you can peruse the PDF copy in the link above (pic) and buy it on amazon or where ever if you really like it and want a hardcopy. It seems to be pretty good, with lots of diagrams and color photos. It seems to be well received by most people.
>>1460683Yeah, that's a serious drawback. It is easy to cook stuff in the sun if there's no ventilation. My first super hot pepper seedlings succumbed to that problem. Evidently, the temps topped out at 135F in the little tent greenhouse I made. lol
>>1461097lol Yeah, the original soil looked a bit sad for the most part. Like it was the cause of some problem. Good to know it was rescued. Citrus like loam and sandy loam with good drainage.
