How can I create an efficient tree farm?

I’ve created a wooden tower with wood platform bridges to find floating islands. As a result, I need a lot of wood and my supply is running low.

I had actually planned for this and created a tree farm, but it isn’t very productive. I set it up as follows, which repeats across a leveled “field” wide enough for forty saplings total. I know the torches aren’t necessary — I used them as a ruler when laying everything out and left some in for looks.

Unfortunately, this seems to produce about one tree per game week or less, which is painfully slow compared to my needs. My suspicion is that the tall grass which grows constantly is blocking the growth of trees, which I know need some room around them. I try to “weed” the farm pretty regularly, but grass starts regrowing by the time I get from one end to the other.

What can I do differently to make my tree farm more efficient?


From the Terraria wiki page on Trees:

Growing 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 a dirt block covered with grass, corrupt grass, crimson grass, hallow grass, a mud block covered
    with jungle grass, or on snow.
  2. The acorn requires one space of open ground to either side.
  3. There must be at least two open tiles between saplings or only one will grow into a tree. This matches the previous rule, i.e. each acorn
    needs both adjacent tiles free, which means the closest two trees can
    be is with two tiles between them.
  4. The acorn requires at least 32 feet (i.e. 16 tiles) of vertical clearance to grow into a tree.
  5. 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 32 feet above the block where the acorn was planted as
    measured by a Depth Meter (e.g, if you are planting an acorn at 300
    feet above, there may only be blocks at 332 feet or higher directly
    above it in order for it to grow into a tree).
  6. Acorns will not grow in the presence of torches, wood platforms or sunflowers within its 2-block radius.
  7. 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.

So, you can’t grow a tree at the edge of a step or cliff, or next to a step or cliff, or at the edge of a patch of grass, even though you can plant acorns there. While trees can, very rarely, grow a distance of three tiles apart (two empty columns between them), they grow much faster at a distance of four tiles apart (with three empty spaces between them). For these reasons, it is recommended to plant acorns every four tiles on a long flat row of surface grass. Tiles more than 14 units above the planted grass do not have any effect on tree growth, so an optimal tree farm can have multiple 15-tile high levels.”

You seem to have your acorns spaced correctly, there are no walls, and I assume you have enough head room. Although it’s not explicitly mentioned in the wiki, your torches may be keeping the trees from growing. Try removing them. At least some of the acorns should grow to full trees in a matter of minutes.
