I'm not sure if anyone mentioned this yet, but you can lay down some transparent qr paths to keep the flowers in check. This game really made the spawn rate of flowers ridiculous.... covering the entire back half of my island with flowers.
it's very pretty but I'm fickle with my decorating and all I can say is if you want to do this be a hundred percent sure otherwise you'll be like me and spend two plus hours and about 10 shovels getting rid of 400 flowers
