How to Make an Automated Cactus Farm

Cactus can be a valuable resource when it comes to building mob traps or making dyes. Farming cactus naturally can be painful and annoying. Luckily, cactus has a special property that allows for easy harvesting. With an automated cactus farm, all you have to do is walk through a door and you'll have all the cactus you need without all the hassle.

Find a strip of land 7 blocks long and 3 blocks wide. Build a wall around the area.

Place a water source in the back left corner.

Place 3 blocks of sand 1 block apart. The current between the sand blocks needs to look as it does in the picture.

Make sure that the current all runs to the same block.

Now place the cactus on the sand blocks. Place blocks diagonally above the cactus. When the cactus grow, they will come into contact with the side of the wall and pop themselves off because cactus cannot touch any other blocks.

Eventually, cactus blocks will pop off and the water current will bring them straight to the entrance for you.

If you need more cactus, simply duplicate the structure you made directly over the existing one as many times as you want. The cactus blocks will fall all the way down to the collection area for you to pick up.

Within minutes, you'll have all the cactus you could need.
