Can You Plant Golden Moneyworts In Rocks – The Secret To Thriving

Written ByHoward Parker

Ever look at those stunning aquascapes with plants seemingly sprouting straight from beautiful rockwork and wonder, “How do they do that?” You love the clean, natural look of a stone or pebble bottom, but you don’t want to give up on the lush, vibrant green of live plants.

It’s a common dilemma for aquarists. You’ve heard that plants need substrate to grow, which can feel limiting if you’re dreaming of a minimalist, rock-heavy design.

I promise you, that dream aquascape is closer than you think. You absolutely can have gorgeous, healthy plants without a deep bed of sand or soil. The secret lies in choosing the right plants and understanding how they grow.

In this complete guide, we’ll dive deep into one of the best plants for the job: Golden Moneywort. We’ll explore exactly can you plant golden moneyworts in rocks, cover the step-by-step methods to do it successfully, and unlock the best practices to ensure they don’t just survive—they thrive.

What is Golden Moneywort (and Why It’s Perfect for Rocks)

Before we start tucking stems into crevices, let’s get to know our star player. Golden Moneywort, or Lysimachia nummularia ‘Aurea’, is a vibrant, lime-green plant that’s a favorite in the aquarium hobby for good reason.

It’s bright, grows quickly, and is incredibly resilient. Don’t worry—this plant is perfect for beginners! Its hardiness makes it very forgiving as you learn.

But the most important characteristic for our purpose is that it’s a stem plant. Unlike plants like Amazon Swords or Cryptocorynes, which have extensive root systems that feed heavily from the substrate, Golden Moneywort is a champ at absorbing nutrients directly from the water column through its leaves and stem. The small, hair-like roots it does grow are primarily for anchoring itself, not for feeding.

This single fact is why the answer to our big question is a resounding yes!

The Big Question: Can You Plant Golden Moneyworts in Rocks?

Let’s get straight to the point. You’re here for the answer, and I’m here to give you the confidence to start your project today. This section of our can you plant golden moneyworts in rocks guide breaks it down.

The Short Answer: Yes, Absolutely!

You can 100% plant Golden Moneyworts in rocks, gravel, or attached directly to hardscape. It’s one of the most versatile and adaptable plants for aquascapes that don’t rely on a traditional, deep nutrient-rich substrate.

The “Why” It Works: The Science Made Simple

As we touched on, Golden Moneywort is a water column feeder. Think of it this way: its leaves and stem are its mouth and stomach. It “eats” the dissolved nutrients—like nitrates, phosphates, and potassium—that are already in your aquarium’s water from fish waste and fertilizers.

Because it isn’t dependent on its roots for nutrition, it doesn’t care if it’s anchored in nutrient-rich aquasoil or wedged between two pieces of slate. As long as it’s secure and has access to light and nutrients in the water, it will be perfectly happy.

How to Plant Golden Moneyworts in Rocks: A Step-by-Step Guide

Okay, theory time is over. Let’s get our hands wet! Here are three tried-and-true methods that aquascapers use every day. Pick the one that best suits your style and your tank’s setup.

Method 1: The Crevice Tuck (The Naturalist’s Approach)

This is the most organic-looking method and works wonderfully in scapes with lots of layered stone or dragon stone.

  1. Prepare Your Stems: Gently remove any foam or pot the plant came in. Trim off any unhealthy-looking lower leaves to expose an inch or two of clean stem. You can group 2-3 stems together.
  2. Find the Perfect Spot: Look for a natural gap, crack, or crevice between two rocks in your hardscape.
  3. Gently Wedge It In: Using your fingers or a pair of aquascaping tweezers, carefully guide the base of the stems into the crevice. Be gentle to avoid snapping the stem.
  4. Secure with a Pebble: If the gap is a little loose, find a small pebble or piece of gravel and gently push it into the crevice alongside the stem to hold it firmly in place.

Method 2: Using Plant Weights (The Tried-and-True Method)

Plant weights are a classic tool for a reason—they work! This is a great option for planting in a shallow layer of gravel or pebbles where tucking isn’t possible.

  1. Choose Your Weight: Make sure you buy lead-free plant weights. Most sold in pet stores today are made of a soft, non-toxic metal.
  2. Bundle and Wrap: Group a few stems of your Golden Moneywort together. Gently wrap the soft weight around the very bottom of the stems, just tight enough to hold them without crushing them.
  3. Position and Conceal: Simply place the weighted bundle where you want it in the tank. You can then push it down into your gravel or strategically place it behind a larger rock to hide the weight from view.

Method 3: The Super Glue Gel Trick (The Aquascaper’s Secret)

This is a pro-level technique that gives you ultimate control over placement. It sounds scary, but it’s perfectly safe when done correctly.

  1. Get the Right Glue: You MUST use a cyanoacrylate-based super glue gel. The gel form is crucial because it’s easier to control and holds better. Common brands like Gorilla Glue Gel or Loctite Super Glue Gel Control work perfectly.
  2. Prep the Surfaces: Take the rock you want to plant on out of the water and pat the attachment point dry with a paper towel. Do the same for the very bottom of the Moneywort stem.
  3. Apply and Hold: Place a tiny dab of glue gel onto the rock. Press the base of the plant stem into the gel and hold it firmly for about 30-60 seconds until it sets.
  4. Place in the Tank: You can immediately and safely place the rock back into your aquarium. The glue is inert and non-toxic once cured, which happens almost instantly in water.

Benefits of Planting Golden Moneyworts in Rocks

Beyond just looking cool, this approach offers some fantastic advantages. Understanding the benefits of can you plant golden moneyworts in rocks can help you create a healthier and more unique aquarium.

  • Aesthetic Freedom: You’re no longer bound by a flat layer of substrate. You can create cascades of green flowing down a rock wall or have plants poking out of a central stone feature. Your creativity is the only limit!
  • Easier Maintenance: A shallow pebble base or bare-bottom tank is much easier to clean with a gravel vacuum. There’s less surface area for detritus to get trapped, leading to a cleaner tank overall.
  • Perfect for Specialty Tanks: This method is ideal for tanks housing fish that dig, like certain cichlids, or for breeding tanks where a substrate-free bottom is preferred.
  • Sustainable and Eco-Friendly Aquascaping: By relying on hardscape you may already have, you can reduce the need for commercially harvested substrates, contributing to a more sustainable can you plant golden moneyworts in rocks setup.

Common Problems with Planting Golden Moneyworts in Rocks (And How to Fix Them!)

While this method is fantastic, it’s not without a few potential hiccups. Don’t worry, though! Here are the most common problems with can you plant golden moneyworts in rocks and their simple solutions.

Problem 1: The Great Escape! (Stems Floating Away)

This is the number one issue for beginners. You plant your beautiful stems, and the next morning they’re all floating at the surface.

The Fix: Revisit your anchoring method. If you used the tucking method, secure it more firmly with a smaller pebble. If you used weights, make sure they are heavy enough. The super glue method almost entirely eliminates this problem.

Problem 2: Melting or Browning Bottoms

Sometimes the lower portion of the stem that is wedged in the rocks may turn brown or “melt” shortly after planting.

The Fix: This is often due to transplant shock or a lack of light and water flow in that specific spot. The top of the plant will usually continue to grow just fine. Simply trim away the healthy top portion once it has grown a bit and replant it. Ensure you are providing adequate liquid fertilizer.

Problem 3: Slow or “Leggy” Growth

Your Moneywort is growing, but it’s tall and spindly with lots of space between the leaves, and the color looks pale.

The Fix: This is almost always a sign of two things: not enough light or not enough nutrients. Golden Moneywort needs at least medium-intensity lighting to stay compact and vibrant. Also, since it’s feeding from the water, you must be dosing a good all-in-one liquid fertilizer regularly.

Golden Moneywort Care Guide for Rock-Based Plantings

To ensure your success, follow these can you plant golden moneyworts in rocks best practices. This simple care guide will keep your plants looking their best.

Lighting Needs

Aim for medium lighting. This provides enough energy for lush, compact growth without being so intense that it encourages algae. A standard LED aquarium light on for 6-8 hours a day is a great starting point.

Fertilization is Key

This is the most critical part of the can you plant golden moneyworts in rocks care guide. Since there’s no nutrient-rich substrate, you must provide food in the water. Use a comprehensive liquid fertilizer like Aquarium Co-Op Easy Green or Seachem Flourish 1-2 times a week according to the bottle’s instructions.

CO2: The Optional Booster

You do not need CO2 injection to grow Golden Moneywort. However, if you provide it, you’ll be rewarded with explosive growth and an even more intense, vibrant color. It’s a great “next step” for aquarists looking to level up their planted tanks.

Pruning and Propagation

One of the best parts about stem plants is that they give you free plants! Once your Moneywort grows tall, simply snip the top 3-4 inches off with scissors. You can then plant this new cutting right back into your rockwork, and it will grow into a whole new plant. It’s that easy!

Frequently Asked Questions About Planting Golden Moneyworts in Rocks

Do I need to use root tabs if I plant Moneywort in rocks?

Nope! Root tabs are solid fertilizers designed to be pushed into a substrate for heavy root-feeding plants. Since Golden Moneywort feeds from the water, root tabs would be ineffective. Stick to a good quality liquid fertilizer.

Can I use any super glue from my junk drawer?

Please don’t! You must use a glue that is 100% cyanoacrylate. Check the ingredients. Crucially, use the gel version, as thin liquid glues can run, make a mess, and are harder to work with. Avoid any “2-part epoxies” or construction adhesives.

How fast does Golden Moneywort grow when planted in rocks?

With proper lighting and regular fertilization, it will grow just as fast as it would in substrate—which is quite fast! You can expect to be trimming and replanting every couple of weeks in a healthy, high-growth setup.

Your Rock-Based Aquascape Awaits!

So, can you plant golden moneyworts in rocks? Not only can you, but it’s a stunning and practical way to design an aquarium that breaks the mold.

You now have the knowledge and the techniques to do it with confidence. Remember the keys to success: anchor your stems securely, provide at least medium light, and be consistent with a quality liquid fertilizer.

Don’t be afraid to experiment. The beauty of aquascaping is that it’s your living piece of art. So grab some stems, get creative with your hardscape, and watch your aquarium transform into the lush, rocky paradise you’ve been dreaming of. Happy scaping!
