Written ByHoward Parker

Ever look at your beautiful Anubias nana and think it’s starting to look a little… unruly? Maybe a few yellowing leaves are spoiling the view, or the rhizome is creeping a bit too far across your favorite piece of driftwood. It’s a common sight for many of us in the aquarium hobby.

You might feel a little hesitant to take a pair of scissors to such a slow-growing, resilient plant. What if you cut it wrong? What if you kill it?

Let me promise you this: trimming this plant is one of the easiest and most rewarding things you can do for your aquarium. Don’t worry—it’s nearly foolproof! In this guide, I’ll walk you through everything you need to know about how to trim anubias nana. We’ll cover the right tools for the job, the step-by-step process for a perfect cut, and how to turn those trimmings into brand new plants for your tank.

Get ready to not only clean up your favorite plant but also multiply it for free!

Why Bother Trimming Anubias Nana? The Surprising Benefits

Before we dive into the “how,” let’s talk about the “why.” Anubias nana is famously low-maintenance, so you might wonder if trimming is even necessary. While you don’t have to trim it often, understanding the benefits of how to trim anubias nana can transform it from a simple plant into a star feature of your aquascape.

Here’s what a little strategic snipping can do:

  • Promotes Plant Health: Older leaves eventually yellow and die. Trimming them off allows the plant to redirect its energy toward producing fresh, vibrant new growth instead of trying to sustain dying foliage. This also prevents decaying matter from fouling your water.
  • Controls Algae: Because Anubias leaves are long-lasting and grow slowly, they can become a prime spot for stubborn algae like Black Beard Algae or Green Spot Algae. Removing affected leaves is often the easiest way to remove the algae itself and keep it from spreading.
  • Encourages Bushier Growth: While trimming won’t make the plant grow faster, it can help shape it. By selectively pruning the rhizome (the thick, stem-like part), you can encourage the plant to sprout new growth points, leading to a fuller, more compact appearance over time.
  • Propagation (Free Plants!): This is the best part! Every time you trim the rhizome, you’re creating a brand-new, independent plant. This is the core of sustainable how to trim anubias nana practices. You can fill out other areas of your tank, start a new one, or even trade with fellow hobbyists.

Gearing Up: The Essential Tools for the Job

You don’t need a surgical suite to get this done, but having the right tools makes the process cleaner, safer for the plant, and much easier for you. Think of it as setting yourself up for success. This is a key part of our how to trim anubias nana care guide.

Here’s your simple toolkit:

  • Sharp Aquascaping Scissors: This is non-negotiable. A sharp, clean cut is vital. Dull scissors will crush the plant’s tissues, leaving a ragged wound that’s susceptible to rot and infection. Stainless steel aquascaping scissors are a fantastic investment for any planted tank enthusiast.
  • A Clean Surface: If you’re removing the plant from the tank to work, have a clean, damp cutting board or a shallow tray ready. This keeps everything contained and prevents the plant from drying out.
  • Aquarium-Safe Glue or Thread: You’ll need something to re-attach your newly propagated pieces. Cyanoacrylate super glue gel (make sure it’s the gel version!) is a hobbyist favorite because it’s fast and safe. You can also use plain cotton thread, which will eventually dissolve after the plant has attached itself.

The Core Technique: A Step-by-Step How to Trim Anubias Nana Guide

Alright, let’s get to the main event. Here is the complete how to how to trim anubias nana process, broken down into simple, manageable steps. Take a deep breath—you’ve got this!

  1. Step 1: Assess Your Plant and Make a Plan

    Before you make a single cut, take a moment to look at your Anubias. Where is it looking overgrown? Do you see any yellow, tattered, or algae-covered leaves? Is the rhizome getting too long and leggy?

    Decide what your goal is. Are you just cleaning up a few bad leaves, or are you looking to split the plant into two or more pieces? Having a plan makes the process much more efficient.

  2. Step 2: Removing Unhealthy or Unwanted Leaves

    This is the simplest part of the trim. It’s like deadheading flowers in a garden.

    Take your sharp scissors and identify a leaf you want to remove. Follow its thin stem (this is called the petiole) all the way down to where it meets the thick, horizontal rhizome. Cut the petiole as close to the rhizome as you can without nicking it. The small stump will wither away on its own.

    Remove all the yellowing, damaged, or heavily algae-covered leaves this way. Your plant will instantly look cleaner and healthier.

  3. Step 3: Trimming and Propagating the Rhizome

    This is where the magic of propagation happens! The rhizome is the lifeblood of the plant, where it stores nutrients and sprouts new leaves and roots. Trimming it correctly is key.

    Look at the rhizome and find a good spot to make a cut. The golden rule is to ensure each new piece has at least 3-5 healthy leaves. This gives the new plant enough energy to establish itself. A piece with only one or two leaves might struggle to survive.

    Using your sharp scissors or a clean razor blade, make a firm, clean cut straight through the rhizome. That’s it! You now have two separate Anubias plants. You can repeat this process on a very long rhizome to create multiple plants, as long as each section meets the 3-5 leaf minimum.

  4. Step 4: Replanting Your New Anubias Cuttings

    Now that you have your new Anubias propagations, it’s time to give them a home. Remember the most important rule of Anubias care: NEVER bury the rhizome in the substrate. Burying it will cause it to rot and kill the plant.

    Instead, you need to attach it to a hard surface like driftwood, lava rock, or other decor.

    • Using Super Glue Gel: Dab a small amount of glue onto the rock or wood where you want to place the plant. Press the rhizome firmly onto the glue for about 30 seconds. You can do this out of the water or even underwater!
    • Using Thread: Simply wrap cotton thread around the rhizome and the object you’re attaching it to a few times. Tie a secure knot. The plant’s roots will eventually grip the surface, and the cotton thread will dissolve over time.

Anubias Nana Care After Trimming: Best Practices for Recovery

One of the best things about Anubias is how incredibly tough it is. It will barely notice you trimmed it. However, following a few how to trim anubias nana best practices will ensure a smooth and speedy recovery.

Keep your water parameters stable, as sudden changes can stress any plant, especially after a trim. The plant might pause its growth for a week or two as it recovers from the cut, but it will soon resume sending out new leaves and roots.

Your new cuttings will also take some time to acclimate. Don’t be alarmed if they don’t show new growth for a few weeks. As long as the existing leaves look healthy and green, the plant is doing just fine.

Avoiding Common Problems with How to Trim Anubias Nana

While the process is straightforward, a few common mistakes can cause trouble. Let’s address these common problems with how to trim anubias nana so you can avoid them entirely.

Mistake #1: Burying the Rhizome

We’ve said it before, but it’s worth repeating because it’s the number one killer of Anubias. The rhizome needs to be exposed to the water column to breathe and absorb nutrients. Always attach it to hardscape, never bury it.

Mistake #2: Using Dull Tools

Using your kitchen scissors or a dull pair of shears will crush and damage the plant cells around the cut. This invites bacterial infections and can lead to rhizome rot. A sharp, clean cut heals quickly and cleanly.

Mistake #3: Cutting the Rhizome Too Small

It can be tempting to create as many new plants as possible, but cutting a piece with only one leaf and no roots is setting it up for failure. Stick to the 3-5 leaf rule to give each new propagation the best chance of survival.

Sustainable and Eco-Friendly Anubias Propagation

In a world where we’re all trying to be a bit more conscious of our impact, your aquarium hobby can be a source of sustainability. Practicing eco-friendly how to trim anubias nana techniques is a perfect example.

Every time you propagate your Anubias, you are creating life from something you already have. This reduces the demand for commercially farmed plants, which cuts down on shipping, packaging, and the overall carbon footprint of the hobby.

Plus, you can share your propagated plants with friends or trade them at your local aquarium club. This builds a stronger community and makes the hobby more accessible for everyone. It’s a win-win for you, your wallet, and the planet.

Frequently Asked Questions About Trimming Anubias Nana

How often should I trim my Anubias Nana?

Very rarely! Anubias are slow growers, so you should only trim them when you see yellowing or damaged leaves, or when the rhizome has grown so long that it’s no longer aesthetically pleasing. For most tanks, this might only be once or twice a year.

Can I trim the roots of Anubias Nana?

Absolutely. The fine, stringy roots are primarily for anchoring the plant to surfaces. They absorb some nutrients, but not like substrate-rooted plants. If they become too long and messy for your liking, you can trim them back without harming the plant.

What do I do if my Anubias rhizome starts to rot after cutting?

If you notice a part of the rhizome becoming soft, brown, and mushy, you need to act fast. Remove the plant from the tank and, using a sharp blade, carefully cut away all the rotted parts until you are left with only firm, healthy green tissue. You can let it air dry for 10-15 minutes before re-attaching it in your tank. This helps the cut “scab over” and prevents the rot from continuing.

Your Turn to Create and Cultivate

See? That wasn’t so scary! You now have a complete understanding of how to trim Anubias nana with confidence. You know how to clean up old leaves, promote healthy growth, and—most excitingly—how to propagate it to create a lush, green aquascape without spending another dime.

Trimming is more than just maintenance; it’s an act of cultivation. It’s your chance to interact with your underwater garden, shaping it into the beautiful scape you’ve always imagined.

So grab your scissors, trust in your new knowledge, and get ready to transform your Anubias. Happy scaping!
