Here we have another achievement for getting 5-stars in one of the garden competition categories. This one is awarded for hitting 5-stars in the "plant selection" category. The easiest way to do this is to run around your property planting edible crops. I aimed for the following, though I know I had more of some of them:
- 10 zucchini
- 10 strawberry
- 10 bunch of raspberries
- 10 raspberries
- 10 pumpkins
- 10 lettuce
- 10 cucumis
- 10 tall blueberries
- 25 each of parsnips and carrots
Just run around like Johny Appleseed and plant as though your life depends on it. When done, enter into a competition, and select "Crop" as your category.
This solution will also unlock the achievement "Vegan". Further, if you do this on the property "Garden after building the house" you will also unlock "According to the rules" for getting 5-stars in the Layout category.
