Acorn

Acorns are items that drop when cutting down trees. For every leaf in a tree, there is an equal number of acorns. Acorns can be planted and eventually grow into trees. These trees do however have a maximum height. They will not grow as high as some of the very large trees seen, which are automatically spawned by the world itself. You can have up to 99 acorns in one stack.

When growing trees keep in mind the saplings needs sufficient space, as when saplings are too close together neither of them will grow. Keep at least 3 spaces in between saplings and keep the ground free of weeds. If you do this correctly the sapling might have already grown the next day.

Note that acorns may only be planted on dirt blocks that grass has grown over, and is above the underground depth level, even if grass is planted down there. It also appears that saplings will not grow above ground if there is a dirt background behind them. The saplings can be destroyed by hitting the block they are planted on with a pickaxe. Doing this will not drop an acorn, the acorn will be wasted and lost forever.

Acorns can also be purchased from the Dryad for 10 copper coins each. This means you cannot produce a situation in which there is no way to collect more wood.

Acorns sell at a value of 2 coppers.
