The Rainbow Fertilizer is a limited prismatic gear introduced during the second half of the Fall Market Event. It’s one of the most vibrant and powerful fertilizers in the game, designed to supercharge plant growth and unlock rare rainbow mutations.
Appearance
The Rainbow Fertilizer has a compact, box-like shape with a bright green circle on the front, displaying three upward-pointing arrows that symbolize growth. A black handle is attached to one side, giving it the look of a small fertilizer dispenser.
When applied to a plant, a radiant rainbow aura surrounds the target, signaling the activation of its magical effects.
The Rainbow Fertilizer stands as one of the most enchanting tools for any dedicated gardener or collector. Its dazzling effects and powerful growth boost make it a true treasure of the Fall Market Event. If you’re looking to enhance your garden even further, don’t forget to buy Grow A Garden pets — they make the perfect companions to bring your vibrant, rainbow-filled garden to life.
Obtainment
Players could originally earn the Rainbow Fertilizer by accumulating at least 500 Fall Energy during the Fall Market Event.
Even though it was limited at the time, it is still obtainable today through the Chubby Chipmunk’s ability.
Usage
When used on a plant, the Rainbow Fertilizer applies the Rainbow variant for 2 hours.
This special effect grants:
- A higher chance for rainbow mutations on produce

However, the Rainbow Fertilizer cannot be stacked with other fertilizers, including Silver Fertilizer or Gold Fertilizer.
Trivia
