Giant Jungle trees grow naturally in the Jungle biomes. When you plant a jungle tree sapling they only grow into regular small trees, but it is possible to grow a giant jungle tree without having to perform any glitches so, how do you make giant jungle trees? Well it’s actually very easy.
To grow a giant jungle tree you need to have 4 jungle tree saplings and a few pieces of bonemeal. It’s hard to say exactly how many pieces you need, sometimes it works first time other times it might end up taking 10 pieces to make the tree grow.
Start by placing 4 of the saplings on the ground in a square. (See the image above). Once you have placed the 4 saplings in a 2×2 square hit one of the saplings with a piece of bonemeal. This can waste quite a few pieces of bonemeal so make sure you have a good few pieces on you before you start. Sometimes the tree will actually grow on its own provided you have the saplings placed in a 2×2 square, but this can often take a day or 2 of in game time for it to actually grow. You can try this if you do not have enough bonemeal.
You can grow a jungle tree outside of the jungle biome as long as you plant the saplings into dirt blocks. If you are walking around on the branches you might find that some start to vanish. If you place some jungle wood blocks around the branches they will not vanish.
