I always cut them down! honestly I forgot digging them up was even an option. maybe if I was doing a project and I knew I'd be reusing them soon then I'd dig them up, but for the most part I prefer cutting them down and growing new ones. gets me more wood, too!
It really depends on if I have enough room elsewhere and how I’m altering the landscape. In the best case scenario I move my trees but sometimes I just have to fully remove them (big RIP to the trees that had to go down for the mush barrens)
I usually will replant them but I do honestly have too many trees (according to Isabelle - joy killer)...so I've been digging some up and trying to sell them here and there.
I like to think by selling them to Nook's he's at least shipping them to some mystery island to be replanted...heh.
It depends on the amount of free space I have in my pockets. Lately, instead of digging them up or cutting them down, I am using quite often the cleanup service from the Island designer app. It's quick and convenient but you lose the wood material that you would get by cutting trees down.
i almost always dig them up, even if i have no intentions on replanting them; trees that i don’t plan on keeping get sold to nook’s and the ones that i do keep get replanted somewhere else aha.
It really depends on your intention. For my case, I don't want to reduce the number of trees. Hence, I just move them. There were special cases that I need to chop some of them and make way for tree stumps!
