The Celestial Mutation, introduced in the Blood Moon update, is one of the rarest and most visually stunning effects in Grow a Garden. But to unlock this glowing transformation, you’ll need a powerful tool: the Star Caller.
Here’s how to get your hands on it—and how to use it effectively for maximum profit and beauty.
⭐ What Is the Star Caller?

🛒 How to Get the Star Caller
The Star Caller can only be purchased from the Blood Shop, which appears during Blood Moon events. Here’s what to know:

Spawns every 3 hours

Found in the empty space next to the Wise Owl NPC

If it’s not available, you’ll need to wait for the next Blood Moon
-
Legendary items are expensive — make sure to save up Sheckles in advance
🧠 Tips to Improve Your Chances
-
Join a populated server to track event timers more easily
-
Check the Blood Shop immediately when it spawns—high-tier gear can sell out fast
-
If you miss out, server hop just before a Blood Moon starts to improve odds
🌌 How to Use the Star Caller
Using the Star Caller is simple but requires some planning:
Step-by-Step:
-
Equip the Star Caller from your backpack
-
Move to a clear area in your garden
-
Click to place the tool—watch for the green radius that appears
-
All crops within that circle become eligible for Celestial mutations
Each Star Caller affects three crops per placement. After that, it becomes inactive.
🧪 Advanced Strategy Tips
-
Avoid overlapping tool areas: Placing multiple Star Callers too close together will waste coverage
-
Target high-value plants: Focus on crops with high sell prices or those used in crafting
-
Track usage: Hover over a placed Star Caller to monitor how many harvests are left
✨ Why Use the Star Caller?
-
Triggers the Celestial Mutation, a rare visual transformation with glowing effects
-
Boosts crop value significantly, making it ideal for income-focused builds
-
Great for rare plant collections and aesthetic-themed gardens
Whether you’re optimizing for cash or crafting the most celestial-looking garden in town, the Star Caller is a powerful tool worth chasing during Blood Moon cycles.
