Coal is the heart of the Smithing update in Grow a Garden. It powers every crafting recipe in the event, from plants and gears to pets and cosmetics. If you want to unlock the best items, you will need a steady supply of coal in different rarities.
This guide explains all the reliable ways to get coal, how the system works, and what coal is used for in the event.
All Ways to Get Coal in Grow a Garden
During the Smithing event, there are three main methods to collect coal.
Each one works differently and serves a different type of player. Here is the full breakdown.
1. Contribute to the Smithing Event
This is the fastest and most consistent way to earn coal.
At the center of the event area, you will find the large furnace and the Blacksmith Smith NPC.
Around the furnace, you will see three submission windows. These are for plants, pets, and gears.
How it works
Submit one plant
Submit one pet
Submit one gear
Once all three items are submitted, the furnace activates and you immediately earn a coal of random rarity.
In addition to coal, your contribution also triggers two bonus effects.
• A ten second crafting time boost for one random station
• A chance to activate a special weather event
This method lets you earn unlimited coal as long as you keep submitting items one at a time.
2. Use the Smithing Dog
The Smithing Dog is a passive coal generator and a great long term method.
You can craft the Smithing Dog at the Pet Crafting Station in the event area.
Smithing Dog recipe
One Dog
Two Rare Coals
Three million sheckles
Once crafted, place the Smithing Dog in your farm. Its passive makes it dig up coal automatically every twelve minutes.
Most drops will be Common Coal, but it occasionally finds Rare or even Legendary Coal.
This is the best method for players who want coal farming to run automatically while they work on other tasks.

3. Treasure Digging
Treasure Digging is the most random method but also one of the most exciting.
Open the in game shop and click Dig Now. You will see a five by five grid covered with red flowers. Dig any tile to uncover what is beneath it.
Coal appears in the reward pool with several rarity levels. The chances are lower than the other methods, but this activity also gives you a shot at rare items like the Gem Egg, Divine Coal, rare plants, and exclusive pets.
You get one dig every five minutes. The event also refreshes daily, or you can reset it manually by paying one trillion sheckles or fifty nine Robux.
All Coal Types in Grow a Garden
Coal comes in four rarities. Each rarity is represented by a different color.
Coal Types Table
| Coal Type | Visual Description | Notes |
|---|---|---|
| Common Coal | Black block with dark grey cracks | Used in most basic recipes |
| Rare Coal | Black block with blue highlights | Required for mid tier crafting |
| Legendary Coal | Black block with gold highlights | Needed for high tier items |
| Divine Coal | Black block with red highlights | Required for top tier event items |
Higher tier coal is harder to obtain but also essential for crafting the strongest seeds, pets, and gears.
What is Coal Used For in Grow a Garden
Coal is required at every crafting station in the Smithing event. You will need it for:
• New plants
• New seeds
• New pets
• New gears
• New cosmetic items
• Event exclusive items like Gem Eggs
You can also crumble coal for sheckles by holding the coal in your hand and clicking, but the sheckle reward is low and not worth it. Always keep your coal for crafting.
Final Thoughts
Coal is the core ingredient that powers the entire Smithing event in Grow a Garden. Whether you want to craft the new Gem Egg, unlock new pets, or speedrun advanced gear, coal is the key to everything.
The fastest way is contributing to the Smithing event, the easiest long term method is using the Smithing Dog, and the most rewarding random method is Treasure Digging.
