Pine Cones can be planted to grow into Evergreen trees. It takes from 7.5 to 10 game hours for them to grow from saplings into small trees. They can also be used as a low-level fuel item. Planted saplings will not appear on the Map until they have progressed into the small tree stage.
When chopping down trees, it should be noted that chopping down a Large Evergreen will provide two Pine Cones, a Medium Evergreen will provide one, and a Small Evergreen will provide none.
Planting Pine Cones can calm and put to sleep nearby Treeguards, whether or not they are aggressive. The chance of this happening is a maximum of 33% when planted near the Treeguard, with a lower chance when planted farther away. The Treeguard will groan in acknowledgement when a Pine Cone is planted within range, even if it has already been pacified.
In the Hamlet DLC, Pine Cones can be bought for 1 Oinc at the Miss Sow's Floral Arrangements in the Pig City; as they are cheap, they are recommended for planting a pine tree farm as soon as possible, as Rainforest Trees only drop seeds during Lush Season, and Tea Trees drop less logs.
During the Winter's Feast event, Pine Cones can be planted in the Festive Tree Planter to create a Winter's Feast Tree. Like regular Evergreens, they take four stages to grow, however, once they are fully grown, they will stop their life cycle.
- In older versions of the game, when the player planted a cone, the plant first sprouted as a small tree, rather than a new sapling.
