Trees

Trees are plants in Terraria that can be chopped down to gather Wood, an essential crafting material. Trees must be chopped down with an Axe, or with explosives, and once destroyed will yield Wood, with a chance of dropping Acorns for growing more Trees.

It is possible to cut off parts of the tree, but cutting at the lowermost center tile will destroy the entire tree. If parts of the tree are left, they will not regrow. A faster but more dangerous alternative to cutting down trees is placing a bucket of lava at the very base and picking it back up immediately.

Tiles beneath trees cannot be destroyed while the tree stands.

Conditions
Planting an acorn in grass will create a Sapling that will eventually grow into a tree of a random size and shape. Saplings can only grow under the following conditions:


 * 1) A planted Acorn can only be planted on grass-covered dirt, and the two adjacent tiles left and right must be either grass or jungle grass-covered.
 * 2) The Acorn requires 2 spaces of open ground to either side. A raised tile will block growth, but a lower tile will not, if it is the second tile away.
 * 3) There must be at least 3 open tiles between saplings or only one will grow into a tree.
 * 4) The Acorn requires at least 15 tiles of vertical clearance to grow into a tree, although they can grow higher if more space is given.
 * 5) The tree must be at least 2 squares away from block walls on either side, to allow room for the branches and tree top to grow.
 * 6) An Acorn will not grow indoors - all background walls or overhanging ledges must be removed, and if you have a ceiling it must be at least 30 feet above the block where the acorn was planted as measured by a depth meter (e.g, if you are planting an acorn at 321 feet above, there may only be blocks at 351 feet or higher directly above it in order for it to grow into a tree).
 * 7) Acorns will not grow in the presence of tall grass, flowers, torches, wood platforms or sunflowers within its 2-block radius. Be sure to trim grass from your tree garden regularly, or place one layer of dirt walls behind it.
 * 8) Saplings must be off-screen in order to become trees. They will not grow when currently in view, unlike most other plants which can spawn while you watch.

Saplings can be destroyed with a Pickaxe.

Corrupt Trees
Corrupt trees are purple trees only found in the Corruption. They behave like normal trees, dropping regular Wood but no Acorns. Normal trees become corrupted if corruption reaches them. It is possible to convert them into normal trees again by using the Purification Powder on them.

Jungle Trees
Jungle trees are darker green, wider trees only found in the Jungle. They spawn randomly on Jungle Grass wide enough for a tree to grow on. Jungle trees drop Wood like normal trees do, but similar to Corrupt trees will not drop any Acorns.
