Master the Zen Tree in Grow a Garden by trading Tranquil fruits for Zen. Unlock top-tier rewards with smart upgrades.

The Zen Tree is your gateway to unlocking the best rewards in the new Zen Event. From pets like the Koi to powerful items like the Pet Shard Tranquil, everything revolves around growing this tree.
But progress requires strategy. You’ll need to gather Tranquil fruits, trade them for Zen, and level up the tree step by step. This guide breaks down the process clearly, so you can focus on what matters: collecting, trading, and upgrading efficiently.
Zen Tree in Grow a Garden Roblox
To grow the Zen Tree in Grow a Garden, you first need to collect a new event currency called Zen. You get Zen by trading Tranquil mutation fruits with the monk NPC named Unk. The tree sits at the center of the Zen Event hub and levels up each time you submit enough Zen. Every level unlocks a new item in the Zen Shop, and the process continues until level 7, which is the max.

Start by obtaining Tranquil mutation fruits. You can get them through three main sources:
- The Zen Aura event
- The Tanchozuru event
- Tranquil mutation pets on your plot
Once you have a Tranquil fruit in your hand, walk up to the monk and press the E key to open the dialogue. Then, choose the option “Take all my Tranquil plants.” The monk only accepts Tranquil mutations, so make sure you’re holding the right type.
Zen is awarded based on the tier of the Tranquil fruit you trade. Here’s the full breakdown:
Crop Tier | Zen Earned |
---|---|
Common | 1 |
Uncommon | 2 |
Rare | 3 |
Legendary | 4 |
Mythical | 5 |
Divine | 6 |
Prismatic | 7 |
Transcendent | 8 |
As you accumulate Zen and trade it in, a progress bar above the monk will fill. When it reaches the threshold for the current level, the Zen Tree upgrades to the next stage. Each stage brings visual changes and unlocks new items in the Zen Shop.

Even after maxing out the tree, you can continue trading Tranquil fruits for Zen. While no new items will unlock beyond level 7, you will still receive level-up rewards, making it a good long-term strategy for farming Chi and Zen.
