A ghostly breeze stirs the soil as the Harvest Reaper’s sigil begins to glow-summoning Severed Spine isn’t just about timing, but mastering the hidden ritual buried deep within Grow a Garden’s eerie fields.
This may look like a scary summoning ritual, but if you’re brave enough to give him all that he requires, you can get rewarded with several exclusive rewards. In this guide, learn about the summoning ritual for the Harvest Reaper in Grow a Garden and how to get the Severed Spine.
How to Summon Severed Spine by Harvest Reaper in Grow a Garden
To summon Severed Spine by Harvest Reaper in Grow a Garden, collect all five ritual seeds and plant them in a circle near the old greenhouse during the Blood Moon event. Use the Reaper’s Scythe to trim nearby corrupted vines, then water each seed with the Crimson Dew obtained from the Dark Orchard. Once the final seed blooms, a shadow will rise from the soil-this is your cue to wield the scythe and call forth Severed Spine. Timing and precision matter, as any delay can cause the ritual to fail and reset the event.
The Harvest Reaper NPC will spawn naturally at the center of the lobby every 2 hours in the Grow a Garden Halloween Event. The central area will be occupied by the Harvest Reaper, the Witch, and the Dead Tree alternatively every hour. So, wait for some time or rejoin the game later to find the Harvest Reaper and complete its quest.
The new NPC will have a set of 25 ritual plates encircling it, burning in orange flames at first. Now, follow the steps below to complete the summoning ritual:
- Go near each plate and view what plant it requires
- Bring out the plant from your backpack and hold it in your hand.
- Press the ‘E‘ key to interact with the plate and then click on the Submit dialogue option.
- This will change the color of the flame from orange to blue.
Notice that the required items will be as simple as a carrot, a pumpkin, or a Jack-o-Lantern. However, some might even have certain mutations attached to the plants, like Spooky or Vamp. As you complete submitting all 25 plants to the ritual plates, and all of them turn blue, you’ll be rewarded.

Best plants to use for the 25 ritual plates
Best Plants for Ritual Plates
In Roblox’s Grow a Garden Harvest Reaper event, the 25 ritual plates each randomly require a specific plant from your inventory, with no fixed list-requirements vary per event and plate. Common demands include basic crops like Carrots, Strawberries, Blueberries, and Pumpkins, alongside rarer ones such as Moon Mango or Ghoul-related plants from the Halloween update.
Preparation Strategy
Stockpile 50-100 of the most frequently requested plants to cover multiples across plates quickly. Prioritize cheap, farmable commons grown in bulk via multiplots:
-
Carrots and Potatoes (Tier 1 basics, always in demand).
-
Strawberries, Blueberries, Tomatoes (early-mid game staples).
-
Pumpkins and Corn (Halloween-themed, high ritual frequency).
Top Recommended Plants
Focus on these high-utility plants based on player reports for fastest ritual completion:
-
Carrots: Ubiquitous requirement; grow endlessly.
-
Strawberries/Blueberries: Berries appear often; mutate for extras.
-
Pumpkins: Event-favored, pairs with Ghoul Garden.
-
Moon Mango/Cursed variants: Rarer but critical for advanced plates.
-
Candy Blossom/Corn: 100% overlap with rewards.
Efficiency Tips
Join high-player servers for shared progress; use pets like the Reaper for crop duplication. Avoid rares until confirmed needed-sell extras for seeds.
Plants traditionally used for protection rituals
Plants like rosemary, sage, and garlic have long traditions in protection rituals across cultures, used to ward off negative energies and evil spirits. These herbs feature prominently in folklore from European, Native American, and Ayurvedic practices for creating spiritual barriers.
Key Protective Plants
-
Rosemary: Hung or burned to repel evil and enhance mental clarity during rituals.
-
White Sage: Smudged in Native American ceremonies to purify spaces and banish negativity.

Garlic: Carried as an amulet in ancient Egyptian and Roman traditions against misfortune.

Lavender: Promotes peace while driving away malevolent forces, per herbal folklore.
Ritual Applications
Burn bundles of sage, cedar, or palo santo to cleanse a home, or place basil and cactus near entrances for ongoing energetic shields. Yarrow and mugwort add layers of defense in spells, often combined for amplified effects.
