if you just want to get 3 stars and don't have immediate outdoor furniture plans, making a grid of fencing should do the trick. talk to her, then take it down (this is what i did lol)

Just create fences around a set of furniture somewhere around the island. Create fencing around your villagers houses and craft then display some DIY furniture. Plant flowers and trees around the fencing and you should be good to go.
20 something pieces of furniture placed outside
at least 7 or 8 residents
50 pieces of fencing
at least 3 different kinds of fruit
plenty of flowers
very little weeds
pick up all fruit, branches, and things you dropped on the island
there might be a bit more, but appealing scenery means that you don't have enough furniture items outside.
