Grow a Garden Ghoul Garden Guide (October 2026): All 10 New Seeds, Black Cat Sets, Witch's Brew, and Candy Corn Prices

Thu Oct 22, 2026 5:25 am

Quick Summary

Grow a Garden's Halloween Event 2026 launched on October 17, 2026 as update 1.72.0, and it is the largest seasonal rotation the game has run this year.
The Ghoul Garden is a separate plot where only Halloween plants grow. Non-Halloween crops, pets, eggs and mutation sprays are all blocked there.
Candy Corn is the seasonal currency. You earn it by selling Halloween plants at the Sinister Sales stand, and you spend it at the Scary Seeds, Frightening Fauna and Demonic Decor stalls.
The Black Cat pays a Haunted Seed Pack for every set of three fruits you feed it. Fifteen sets earn an Exotic Haunted Seed Pack, then the cycle resets.
Witch's Brew is a shared cauldron on a two minute cooldown, with separate contributor and top contributor payouts.
A Part 2 of the event is already teased, with promotional art dated October 22, so more content is likely within days.

What Changed on October 17

Grow a Garden added its Halloween Event 2026 on October 17, 2026 as update 1.72.0. The patch notes came from the game's official Discord server and were published by Sportskeeda the following day. The update is a full seasonal rotation rather than a small patch. It adds a new garden type, a new currency, ten new plants, a pet egg, crates, a gear box, seven cosmetics and a fence.

Part 1 covered the Ghoul Garden itself, the Black Cat quest line, Witch's Brew, the Halloween Market and a batch of Ghoul Garden themed mini achievements. The Black Cat quests and Witch's Brew are returning activities from the 2025 event, and the Ghoul Garden is the new part. A promotional image for Part 2 of the event was uploaded to the wiki on October 22, and the wiki's Black Cat section now carries spoilers for the second part, so Part 2 is the next thing to land.

Grow a Garden is worth paying attention to because of its scale. The game peaked at 22.3 million concurrent players on August 23, 2025, during a mock admin war with Steal a Brainrot, and it had already passed 16 million once in June of that year. Seasonal events are the moments the player base comes back in force, and Halloween is the strongest theme the game has for it.

How the Ghoul Garden Works

The Ghoul Garden is a second plot you equip from the game menu. It is not a skin on your normal garden, and it does not share its rules. According to the wiki, the restrictions are strict:

Only Halloween plants can be placed in a Ghoul Garden.
Non-Halloween crops, pets and eggs cannot be placed there.
Only the base sprinkler from the gear shop and the Haunted Sprinkler can be placed. Other sprinklers are blocked.
Mutation sprays cannot be used in a Ghoul Garden.
The top HUD buttons switch to a Halloween theme while you are inside.

The practical effect is that the Ghoul Garden is a self contained loop. You buy Halloween seeds at the Scary Seeds Shop, plant them, harvest, and sell the harvest at the Sinister Sales stand for Candy Corn. There is no separate currency to unlock before you can start.

One quirk is worth knowing. Seeds pulled from Haunted Seed Packs can be planted in your normal garden, but seeds bought at the Scary Seeds Shop cannot. That distinction matters if you are farming a specific plant to move onto your main plot.

Your First Hour in the Event

If you are starting from a normal garden, this order keeps you from wasting Candy Corn:

Equip the Ghoul Garden from the game menu and check the Scary Seeds Shop for the cheapest seed in stock.
Plant Candy Corn Carrots and Spider Shrubs first. Both are always in stock, and both feed the early Black Cat sets.
Harvest and sell at the Sinister Sales stand to build a Candy Corn buffer before you touch the expensive seeds.
Feed the Black Cat as soon as you can match a set. The Haunted Seed Packs are the only route to planting Halloween seeds outside the Ghoul Garden.
Fill the Witch's Brew cauldron whenever it is open. It is free Candy Corn if you already have Halloween fruit.
Save your Candy Corn until Part 2 if you can. The Haunted Hallow at 50,000 is the prize, and the cheaper items will still be there later.

The Halloween Market and What Things Cost

The market splits into three stalls. Scary Seeds sells seeds, Frightening Fauna sells pets, and Demonic Decor sells cosmetics. Everything takes Candy Corn, Robux, or Trade Tokens, and the shop restocks every five minutes.

Here is the seed stock as listed on the wiki, with the Candy Corn price, the Robux price, the stock chance and how many units appear per restock:

Candy Corn Carrot: 10 Candy Corn or 59 Robux, Common, 100 percent stock chance, 5 to 10 per restock.
Spider Shrub: 50 Candy Corn or 139 Robux, Uncommon, 100 percent, 1 to 3.
Haunted Sprinkler: 150 Candy Corn or 199 Robux, Uncommon, 20 percent, 1.
Pumpkin Lantern: 350 Candy Corn or 189 Robux, Rare, 25 percent, 1 to 3.
Candy Cluster: 400 Candy Corn or 319 Robux, Rare, 20 percent, 1 to 2.
Witch's Broom: 500 Candy Corn or 149 Robux, Legendary, 12.5 percent, 2 to 4.
Webberry: 900 Candy Corn or 449 Robux, Legendary, 7.14 percent, 1 to 2.
Blood Kiwi: 10,000 Candy Corn or 499 Robux, Mythical, 5 percent, 1.
Fang Root: 18,500 Candy Corn or 799 Robux, Divine, 3.13 percent, 1.
Haunted Hallow: 50,000 Candy Corn or 1,299 Robux, Prismatic, 1.67 percent, 1.

The pets are sold at Frightening Fauna. The Haunted Egg is the headline item at 1,500 Candy Corn or 149 Robux, always in stock, and it has four possible pets inside. The wiki lists Grave Crab at 1,200, Goat at 1,000, Ghost Bear at 2,500, Wolf at 6,000, Frankenstein's Bear at 7,500, Dark Spriggan at 12,000, Reaper at 25,000 and Eyeball Monster at 30,000 Candy Corn.

The official patch notes name four pets for Part 1: Haunted Knight, Eyeball Monster, Gargoyle, and four or more beyond that. The wiki's pet list for the event adds Grave Crab, Frankenstein's Bear, Skull Snail, Lantern Wisp, Gargoyle, Haunted Knight and Eyeball Monster.

For cosmetics, the wiki lists Haunted Well, Spider Web Bench, Gothic Candelabra, Halloween Mat, Candy Bowl, Zombie Hand and Webbed Picnic Bench, plus a new Halloween fence. Individual cosmetics run from the Pumpkin Set at 50 Candy Corn or 99 Robux up to the Sarcophagus at 600 Candy Corn or 319 Robux.

The Black Cat and Haunted Seed Packs

The Black Cat is the main free progression route in the event. You feed it Halloween plants, it asks for three specific plants per set, and each completed set pays one Haunted Seed Pack.

Some sets require the Haunted mutation on one or more of the three plants. That matters because the Haunted mutation is a crop mutation introduced with the event, and there is a pet mutation of the same name. Sets 1 through 14 each pay a standard Haunted Seed Pack. Set 15 is the payoff. It pays an Exotic Haunted Seed Pack, which the patch notes describe as having a chance at rainbow packs. After set 15 the quest line resets and can be repeated.

The Haunted Seed Pack contains nine possible seeds, and the Haunted Crate holds six possible cosmetics. Both are the route to getting Halloween seeds into a normal garden, since Scary Seeds Shop purchases are locked to the Ghoul Garden.

Witch's Brew, Trick-or-Treating and the Weather

Witch's Brew returns from the 2025 event. The cauldron sits on the event island and anyone can fill it with Halloween fruits or fruits carrying a Halloween mutation. Higher tier fruit is worth more points. Once the cauldron fills, it goes on a two minute cooldown before it can be filled again.

There are two reward tiers. Every contributor gets Candy Corn, with a small chance at a Haunted Egg, a Haunted Crate or a Halloween Gear Box 2026. The top contributor gets a larger payout: more Candy Corn, a 50 percent chance at two Haunted Eggs, and a 50 percent chance at two Haunted Crates.

Trick-or-Treating is a separate action at the Sinister Sales stand. You pay Candy Corn to do it, you get a random reward, and then an eight hour cooldown starts.

The event also runs Halloween cycles. Every so often the game shifts into Halloween themed weather that grants mutations, with Full Moon and Bat Attack named as the two weather types on the wiki. The exact interval is listed as TBA there, so do not plan around a fixed timer.

One plant deserves its own mention. Dracuvine mutates a nearby fruit with the Vamp mutation every five minutes, which makes it the most useful Halloween plant for pushing mutations through the Black Cat sets.

What Part 2 Might Add

The wiki carries a second promotional image for the Halloween Event 2026 dated October 22, and it flags the Black Cat section as containing spoilers for the second part of the event. The wiki's update log lists update 1.72.0 on October 17 as Halloween Event 2026 Part 1, which confirms the event is structured as a multi part rollout rather than a single patch.

I would not spend the last of your Candy Corn on the cheapest stall items right now. If Part 2 follows the same pattern as earlier seasonal events, the better stock arrives with it, and the cheapest seeds and cosmetics are the ones that get replaced.

FAQ

Can I plant Ghoul Garden seeds in my normal garden?
No. Seeds bought at the Scary Seeds Shop can only be planted in the Ghoul Garden. Seeds obtained from Haunted Seed Packs can be planted in your regular garden.

How do I earn Candy Corn?
Sell Halloween plants at the Sinister Sales stand, contribute to Witch's Brew, or trick or treat at the Sinister Sales stand. You also earn Candy Corn from mini achievements and from the market stalls.

How many Black Cat sets are there?
Fifteen. Each completed set pays a Haunted Seed Pack, and set 15 pays an Exotic Haunted Seed Pack with a chance at rainbow packs. After set 15 the line resets and can be repeated.

What is the Haunted Egg?
It is the event pet egg, sold at Frightening Fauna for 1,500 Candy Corn or 149 Robux and always in stock. It contains four possible pets. The wiki does not state an expiry for the egg itself, only that the event is seasonal.

What is the Haunted mutation?
Haunted is a crop mutation introduced with the Halloween Event 2026, and there is a pet mutation of the same name. Several Black Cat sets require at least one plant carrying the Haunted mutation, so it is the mutation to farm first.

Does the Ghoul Garden share my normal garden's sprinklers?
Almost none of them. Only the base sprinkler from the gear shop and the Haunted Sprinkler can be placed in a Ghoul Garden, and mutation sprays cannot be used there at all.
