If you’ve just jumped into the new update in Grow a Garden, the first thing you will notice is a huge tree in the middle of the play area. That’s the Zen Tree, and it’s not just for show. Upgrading the Zen Tree is the key to unlocking most of the good stuff in the new Zen shop. So, in this guide, learn how to grow the Zen Tree in Grow a Garden and what rewards you get for doing it.
What Is Zen and How to Get It?
Zen is a new currency in Grow a Garden that helps grow the Zen Tree. To get it, players must get the Tranquil mutation fruits first. You can get the new mutation through the Zen Aura event, Tanchozuru, or the Tranquil mutation pets. Once you have it, here is how to get Zen in the game:
- Walk to the Zen monk NPC and click the E key to open the dialogue options.
- Note that he asks for only Tranquil plants, so hold out one if you have it.
- With the plant in your hand, press the “Take all my Tranquil plants” dialogue to hand it over to the NPC for Zen.

How to Grow the Zen Tree in Grow a Garden
The Zen Tree is located in the middle of the new Zen Event hub in Grow a Garden. As you collect Zen, the tree will start growing. So, when you hand over Tranquil fruits to the NPC, the bar above him will fill up. Each level you complete will upgrade the plant to the next stage. Repeat the process 7 times to max the tree level.
The Zen you get from fruits is decided based on tiers. Here is a breakdown of the trading values for different tiers of crops in Grow a Garden:
- Common: 1 Zen
- Uncommon: 2 Zen
- Rare: 3 Zen
- Legendary: 4 Zen
- Mythical: 5 Zen
- Divine: 6 Zen
- Prismatic: 7 Zen
- Transcendent: 8 Zen

Growth Level Zen Required Item Unlocked in Shop 1 40 Zenflare Seed 2 60 Zen Crate 3 90 Soft Sunshine Seed 4 130 Koi 5 180 Zen Gnome Crate 6 245 Spiked Mango 7 325 Pet Shard Tranquil
Why Should You Upgrade the Zen Tree in Grow a Garden
Upgrading the tree is a major part of the latest Grow a Garden update. Reaching stage 7 will unlock new items in the Zen Shop. This includes the Koi Pet, Spiked Mango, and Pet Shard Tranquil. All of them are great for collectors or for boosting your in-game economy.
The Pet Shard Tranquil is especially useful since it lets you apply the Tranquil pet mutation. That means more Tranquil plants on your plot, helping you earn extra Chi and Zen faster.
Even after maxing out the tree, you can still give Tranquil fruits to the monk. While it won’t unlock anything new, you’ll still get the level-up rewards each time. So, to farm Chi faster and access the best Zen Shop items, upgrading the tree early is a smart move.
