How To Create a Minecraft Kelp Farm



Ever find yourself running low on kelp in Minecraft? It’s a surprisingly useful resource, used for crafting potions, fueling furnaces (one kelp block can smelt 20 items!), and even breeding axolotls. But fear not, kelp farming is here to save the day!

In this guide, I’ll walk you through the step-by-step process of creating your very own Minecraft kelp farm.

It’s a simple and efficient way to ensure a steady supply of this valuable resource, freeing you up to focus on more important things, like building your next epic creation. So, grab your pickaxe and let’s dive in!

How Do I Create a Minecraft Kelp Farm?

Ah, kelp. The underwater wonder that keeps our Minecraft furnaces burning and our potions flowing. But manually harvesting it can be a tedious chore. Fear not, fellow crafter! 

Today, we’re diving deep (well, not that deep) to learn how to construct a nifty kelp farm. This bad boy will generate a steady supply of leafy goodness with minimal effort on your part.

There are two main approaches to kelp farming: simple and automatic. The simple method is perfect for beginners, while the automatic option offers a more hands-off experience (ideal for potion enthusiasts with carpal tunnel concerns). Let’s tackle the simple method first.

The Not-So-Simple (But Still Easy) Kelp Farm

For this farm, you’ll need:

  • A bucket of water
  • Some blocks (doesn’t matter what kind)
  • Kelp (which you can get by breaking it underwater)
  • A chest (optional, but highly recommended)
  1. Finding Your Ocean Oasis: First, locate a nice big ocean biome. Kelp grows naturally in ocean biomes, so you shouldn’t have to look far.
  2. Building the Base: Now, here comes the slightly not-so-simple part. You’ll need to create a water source at least one block deep. But here’s the trick: the water source needs to be surrounded by blocks on all sides except the top. This will prevent the water from flowing outwards and creating a giant (and unnecessary) underwater lake.
  3. Planting the Seeds: With your water source contained, it’s time to plant! Grab your kelp and strategically place it in the water source. Kelp grows upwards, so you can stack up to four pieces on a single block of water.
  4. Let it Grow, Let it Grow: Now comes the easiest part: waiting. Kelp grows surprisingly fast, so you’ll see results in no time. Once it reaches its full height, simply break the mature kelp and it will drop new kelp strands that you can replant or store in your chest (if you brought one).

Pro Tip: For an even faster harvest, you can use a tool with the “Fortune” enchantment. This will increase the amount of kelp you get from each harvest.

Take it to the Next Level: Automatic Kelp Farm

Feeling fancy? Let’s build an automatic farm that collects the kelp for you. This method uses pistons and redstone, so it’s a bit more complex. If you’re new to Redstone mechanics, there are plenty of great tutorials online to get you started. Here’s a quick overview:

  1. Building the Core: This involves creating a piston contraption that extends and retracts over your kelp, breaking it when it reaches full height. The Redstone will power the pistons on a timer, giving your kelp time to regrow.
  2. Water Flow is Key: Similar to the simple farm, you’ll need a contained water source. However, you’ll also need to design a water flow system that channels the broken kelp towards a collection point, like a hopper leading to a chest.
  3. Reap the Rewards: With your Redstone magic in place, your automatic farm should be good to go! Stand back, relax, and watch that chest fill up with kelp.


Building an automatic farm might seem daunting at first, but trust me, the feeling of having a self-sufficient kelp supply is incredibly satisfying. 

There are many video tutorials online that offer step-by-step instructions with visuals, making the process much easier.

So, there you have it! With a kelp farm in your arsenal, you’ll never have to worry about running out of this essential underwater resource. Now get out there, craft something amazing, and keep on kelping!
