Instructions
Fertilize each plant as much as you can. A fully fertilized plant can provide up to three bonus growth awards which you'll be unable to receive from a plant that isn't fully fertilized.
Buy domestic pinata variations from Miss Petula's Paper Pets, then romance these with each other and other pinatas you have in your garden. You'll earn an award for each successful romance.
Create variant pinata out of the species you do have in your garden by feeding them different items to try and get different colors. For example, if you feed a turnip to a Whirlm, it will change its color to purple, earning you experience points.
