by

The Harvest Reaper is one of the biggest additions in Grow a Garden’s Ghoul Garden Part 3 update.

This eerie NPC allows players to perform a summoning ritual for exclusive Halloween rewards, including the Severed Spine, one of the most sought-after limited-time items in the game.

Here’s a complete guide on how to find the Harvest Reaper, complete the ritual, and summon the Severed Spine in Grow a Garden.

What Is the Harvest Reaper Event?

The Harvest Reaper is a dark, hooded NPC who appears at the center of the main lobby every 2 hours, alternating with the Witch and the Dead Tree.

When active, the Reaper is surrounded by 25 ritual plates with orange flames, each showing a plant or item that you must submit.

Completing all ritual submissions will summon the Severed Spine and reward every participating player with extra loot.

How to Summon Severed Spine in Grow a Garden

Follow these steps to perform the Harvest Reaper ritual and summon the Severed Spine:

1. Find the Harvest Reaper

The Reaper spawns at the center of the lobby every 2 hours and remains for a full hour.

If you don’t see it, you may have arrived during the Witch or Dead Tree rotation — just wait or rejoin the game after the next hour.

2. Check Each Ritual Plate

Once the Reaper is active, walk around the area and inspect the 25 ritual plates.

Each plate displays a specific plant requirement, such as Carrot, Pumpkin, Banesberry, or Poison Apple.

Some of these plants may even need special mutations like Spooky or Vamp.

3. Submit the Required Plants

  • Hold the correct plant from your backpack.

  • Stand in front of a ritual plate.

  • Press E to interact.

  • Choose Submit when prompted.

When done correctly, the flame on that plate will change from orange to blue, indicating successful submission.

4. Complete All 25 Plates

Continue this process until all 25 ritual plates turn blue.

Once complete, the summoning ritual is considered finished, and the Harvest Reaper will reward you automatically.

All Harvest Reaper Rewards

After the ritual is complete, every contributing player receives rewards from the Reaper.

Limited-Time Reward

  • Severed Spine – A unique back gear that “punishes stealers within a small range.”

    • Available once per Reaper visit.

    • Only 500 units are available in stock each time the Reaper spawns.

Guaranteed Rewards

  • Spooky Chest (100%) – Contains rare Halloween pets and seeds like Mummy and Wereplant.

  • Candy Corn (100%) – Used as currency in the Halloween Market for buying exclusive pets and cosmetics.

Tips for Completing the Summoning Fast

  • Bring a variety of plants. Many ritual plates require common crops like Carrot, Pumpkin, or Jack-o’-Lantern. Keep a few of each ready in your inventory.

  • Join an active server. Players can submit plants together, which helps complete all 25 plates faster.

  • Use the Vamp or Spooky Mutations. Some plates demand mutated plants, so having both ready ensures you don’t get stuck.

  • Be early. Severed Spine stocks are limited per spawn, and once they run out, you’ll need to wait for the next event cycle.

What Is the Severed Spine?

The Severed Spine is a limited Halloween gear item exclusive to the Harvest Reaper event.

When equipped, it activates a small radius that punishes players who try to steal your plants, making it a defensive item for competitive gardens.

It’s one of the rarest collectibles in Grow a Garden, available only during the Halloween event period and likely to become unobtainable afterward.

Summary

Final Thoughts

The Harvest Reaper event is one of the most rewarding,  and visually striking, Halloween rituals in Grow a Garden.

Submitting all 25 plants not only gives you the Severed Spine but also guarantees a Spooky Chest, making it worth participating every time it appears.

If you want one of the rarest gears in the game, make sure to gather your plants early, join an active lobby, and help summon the Harvest Reaper before its 500-stock limit disappears.
