Pine Trees can be found growing naturally in the Pine Forest biome. A pine tree can naturally spawn on Fir Grass blocks in any biome.
Pine trees can be chopped down with a Copper Axe or better. It will provide 3 Hard Wood Logs, 4 if the stump is chopped down, and 1-2 Pine Cones for replanting. The base selling price of a Pine Cone is 4.
Dig a hole to bury the pine cone to grow a pine tree in any biome in dirt or sand. It will grow to full height 5 days after being planted.
Use the Plant Book on the plant to show maturity. When fully grown the book will no longer show data.
To create a Hard Wood Log Stool, bury a Fertilizer bag into the ground near/next to a fully grown Blackwood Tree or Pine Tree then sleep for the tree to change to a giant variety. If using seeds, the tree will need to grow to full size before it will change to a giant. Cutting down a giant tree will leave behind a stump that the player can pick up.
See infographic 'How to grow a large tree'.
The base selling price of a Hard Wood Log Stool is 435.
