Most of them do. Sometimes they are chopped down by the parks department. Like I said, it's about climate, drought tolerance, amount of sun/shade that it receives. On some, I will water them for the first year.
Off topic but did Fukuoka include fruit tree seeds in his seed balls? I understand that with seed balls, plants probably get naturally thinned out with the weaker slower growing plants growing in the shade of another plant thus more likely to be eaten by insects because it's weak. But how would this work for trees that are growing too close? I'm sure that in a forest, eventually over a hundred year or so trees naturally thin out to their optimum spacing with weaker trees dieing earlier and the lucky trees that are spaced out more evenly grow healthy. But wouldn't this process take like a hundred years? My question is when doing Fukuoka gardening , how do you approach planting fruit trees? Would Fukuoka just include them in his seedball which probably would result in overcrowded fruit trees or would he manually plant them perfectly spaced for his orchard?
I'm not sure about his style of gardening, so I can't speak to that specifically. However, I do know of people planting trees by seed in clay cubes in arid regions without watering and the trees have sometimes made it.
As for tree spacing, that's more complicated from what I've seen. Sometimes people get away with spacing trees closer together. The trees adapt as they grow up and are fine. Yet sometimes overly dense plantings cause the trees to be stressed out and compete too much for resources like water. In the Pacific Northwest, for example, the summers have gotten drier and hotter, which has stressed the trees more. Personally I would go for a planned spacing just to be sure, but plenty of people are more experimental and it works for them
