Trees

Trees are destructible plants in Terraria, specifically for the purposes of gathering wood for various uses, such as building or crafting. They must be harvested with an axe (or blown up with Bombs or Dynamite), and when cut down will yield Wood and possibly Acorn for each tree tile above the point it was cut; this will leave tree stumps when cut above the bottom center tile, and it is possible to prune trees by chopping off only the branches or roots. Any tiles beneath trees cannot be destroyed while the tree stands. Pre-generated trees may grow much higher than planted trees.

Sapling
Planting an acorn in grass will create a Sapling which will eventually grow into a tree of a random size and shape. Saplings can only grow when the following rules for growing are met:


 * 1) A planted Acorn can only be planted on grass-covered dirt, and the two adjacent tiles immediately to the planted-on tile's left and right sides must be grass-covered dirt as well.
 * 2) The Acorn requires 2 spaces of open ground to either side. A raised tile will block growth, but a lower tile will not.
 * 3) There must be at least 3 open tiles between saplings or only one will grow into a tree.
 * 4) 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).
 * 5) 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.

Corrupted trees


Since the 1.0.3 update, trees no longer destroy themselves when corruption reaches it, instead it becomes corrupted, turning into a purple color. It is possible to convert them into normal trees again by using the Purification Powder on it. Corrupted trees can still be cut down for wood and acorn.

Jungle trees
In an artificial Jungle above 0 feet a tree with a darker green leaves will grow
