Tutorials/Tree farming

Tree farming is the process of planting a large number of saplings and waiting for them to grow into trees. These trees are then harvested for logs and more saplings, which can be used to grow another generation of trees. This can be repeated indefinitely, yielding a regular supply of logs without the hassle of covering large areas of terrain.

Some players prefer to farm larger trees, as they yield more logs per tree or per sapling. Other players prefer to farm smaller trees, as all the wood can be easily harvested from the ground and "floating canopies" do not persist for as long. For more information on the mechanics of tree growth, consult the article on trees.

Efficient tree farming
Trees now grow branches if the height is capped at 8.

Since trees begin to grow branches on their main trunks once they reach a height of 6 blocks or more and the player can only harvest 6 blocks above the ground without climbing on something, the most efficient tree farm designs limit the height of trees to 8 blocks. This allows 6 blocks of logs as a "trunk" and 2 block of leaves above that. This is accomplished by adding a ceiling at 9th block above the ground, leaving a space 8 blocks high in which trees can grow. This allows all of the wood from the trees to be harvested quickly and with minimal effort.

It should be noted that leaving 8 blocks of space for trees to grow will not guarantee that all trees grow to this height. Trees will grow with trunks 4, 5 and 6 blocks in height, but not higher.

While prior to the Halloween update (31 Oct 2010), leaves were able to break glass and torches when growing horizontally, that is no longer true in post-Halloween and Beta versions.

Note: As of Beta 1.2_01 trees once again break torches - reportedly pine trees, more specifically.

Since trees will grow quite happily underground with a nearby light source, and will grow when in direct or diagonal contact with other trees, quite compact arrangements can be used for efficient use of space. The images to the right show that trees will grow quite happily in confined spaces and in close packed arrangements.

Underground saplings rely on torch light to grow. Various patterns of saplings and torches can be used to achieve varying degrees of space efficiency. Since saplings only require light level 9 to grow, a single torch starting at light level 14 can sufficiently light 60 saplings. However, this torch-efficient model comes at the cost of stability. Trees can grow and block the torch light to other saplings. The most space-efficient way to prevent grown trees from blocking light to other saplings is to have every sapling directly next to a torch (not diagonal). This strategy yields a maximum space efficiency of 80% since the pattern is made up of units of 1 torch + 4 saplings. The plus-sign shaped units can be arranged to completely fill an area as shown in the image to the right. Underground tree farms should stay clear of magma because a bug relating to southwest rule may let magma affect any leaf/wood blocks occupying the same corner.
