Written ByHoward Parker

Have you ever watched your lush green Moneywort (Bacopa monnieri) reach the top of your aquarium and wondered, “What now?” You might trim it back and replant the cuttings, but a little voice asks what would happen if you just… let it go.

I’m here to tell you that letting it grow is one of the most rewarding things you can do! The answer to can moneywort grow out of water is a resounding YES, and it’s not just possible—it’s spectacular.

In this complete guide, I’m going to walk you through everything you need to know. We’ll cover how to encourage this unique growth, the incredible benefits it brings to your tank, and how to care for your plant as it transitions from a fully aquatic life to one that bridges two worlds.

Get ready to transform the top of your aquarium into a stunning, living landscape.

Understanding Moneywort’s Dual Nature: The Secret to Above-Water Growth

Before we dive into the “how,” let’s talk about the “why.” Why is Moneywort so good at this? It all comes down to its natural habitat. In the wild, Moneywort is a “marginal” or “bog” plant. This means it thrives in wetlands, marshes, and along the edges of ponds and streams.

It spends its life with its roots submerged in mud or water while its stems and leaves happily reach for the sky. This adaptability is hardwired into its DNA, making it a perfect candidate for growing out of our home aquariums.

When you allow Moneywort to breach the surface, you’ll witness a fascinating transformation:

  • Submersed Growth (Underwater): The leaves are typically bright green, softer, and more delicate. They are perfectly designed to absorb nutrients directly from the water column.
  • Emersed Growth (Above Water): The leaves that grow in the open air become thicker, rounder, and often a deeper shade of green. They develop a waxy coating called a cuticle to prevent them from drying out. You might even be rewarded with tiny, beautiful white or light-blue flowers!

This dual ability is what makes the answer to “can moneywort grow out of water” so exciting. You’re not forcing the plant to do something unnatural; you’re simply giving it the chance to express its true self.

The Amazing Benefits of Growing Moneywort Out of Water

Allowing your Moneywort to grow emersed isn’t just a cool science experiment; it offers a host of practical and aesthetic advantages for your aquarium. This is one of the most overlooked benefits of can moneywort grow out of water setups.

Here are just a few reasons to give it a try:

  • Creates a Stunning Visual Bridge: Emersed growth connects the underwater world of your fish with the room it’s in. It creates a lush, jungle-like canopy that adds incredible depth and a naturalistic feel to your aquascape.
  • Superior Filtration Power: Plants are nitrate-sucking powerhouses. When Moneywort grows emersed, it gains access to unlimited atmospheric CO2, supercharging its growth. This means it pulls even more nitrates and other waste products from your water, leading to a healthier, more stable environment for your fish.
  • Provides Shelter and Exploration: The overhanging leaves and stems create shady spots and hiding places for surface-dwelling fish like Bettas or Gouramis. It also provides a fantastic playground for shrimp and snails who love to explore the emergent stems.
  • Reduces Algae Growth: By consuming excess nutrients so efficiently, emersed Moneywort directly competes with algae. A thriving canopy of Moneywort often means a cleaner, algae-free tank below.
  • A Chance to See it Flower: One of the biggest rewards is seeing your Moneywort produce its delicate little flowers. This is something that rarely, if ever, happens when the plant is fully submerged.

How to Get Moneywort to Grow Out of Water: A Step-by-Step Guide

Ready to create your own aquarium canopy? Don’t worry—it’s easier than you think! This simple can moneywort grow out of water guide will set you up for success. Follow these steps, and you’ll be on your way.

  1. Step 1: Start with Healthy, Tall Plants

    Your journey begins with strong, healthy Moneywort that is already well-established in your tank. You want plants that are tall enough to be within a few inches of the water’s surface or are already touching it. Healthy stems are the foundation for strong emersed growth.

  2. Step 2: Provide a Clear Path Upwards

    Ensure your Moneywort has an unobstructed path to the surface. Plant it towards the back of the tank, perhaps near a piece of driftwood or rock that it can use for support as it grows taller. In low-tech tanks, you can even let a cutting float, and it will often orient itself towards the light and begin the transition on its own.

  3. Step 3: Adjust Your Lighting

    This is one of the most critical can moneywort grow out of water tips. The light that penetrates water is different from the light the plant will need in open air. Your standard aquarium light is a great start, but make sure it’s positioned directly above the area where the Moneywort will emerge. A full-spectrum LED light is ideal. The key is to provide direct, intense light to the emersed leaves.

  4. Step 4: Manage Humidity (The Secret Ingredient)

    The biggest challenge for a newly emerged plant is drying out. The air in our homes is much drier than the 100% humidity it’s used to. A tight-fitting glass lid or canopy is your best friend here. It traps moisture and creates the humid microclimate the plant needs to adapt. If you have an open-top tank, you may need to mist the leaves once or twice a day with dechlorinated water.

  5. Step 5: Be Patient and Observe

    The transition isn’t instant. The first few leaves that pop out of the water might struggle or even melt back a bit. This is normal! The plant is busy growing a new type of leaf suited for the air. Give it a couple of weeks, and you’ll soon see those tough, waxy emersed leaves take over. Don’t give up too early.

Emersed Moneywort Care Guide: Best Practices for Thriving Growth

Once your Moneywort has successfully breached the surface, a few adjustments to your routine will keep it thriving. This can moneywort grow out of water care guide focuses on maintaining that beautiful, lush canopy.

Lighting for Emersed Growth

Your Moneywort now needs strong light on its upper leaves. Aim for a photoperiod of 8-10 hours per day. If the leaves look pale or the stems are getting “leggy” (long and thin), it’s a sign they need more intense light. A simple clip-on LED spotlight aimed at the growth can work wonders.

Humidity and Airflow

While high humidity is crucial for the transition, some airflow is also important to prevent mold. If you have a full canopy, opening it for a few minutes each day can help. For open-top tanks, continue misting regularly, especially if your home’s air is dry.

Nutrient Supply

Remember, the plant’s roots are still in your aquarium, drawing all their nutrients from the water. Continue your regular fertilization routine. A good quality, comprehensive liquid fertilizer is essential to provide the macronutrients and micronutrients it needs to support its supercharged emersed growth.

Pruning and Shaping

Emersed Moneywort can grow very quickly! Don’t be afraid to prune it to maintain the shape you want. Trimming the tips will encourage the plant to become bushier and fuller. Plus, you can simply replant the cuttings back into the substrate to grow more stems!

Troubleshooting Common Problems with Emersed Moneywort Growth

Even with the best care, you might run into a snag. Here’s a look at some common problems with can moneywort grow out of water projects and how to solve them.

Problem: The Leaves Are Drying Out and Crispy

This is almost always a humidity issue. The transition from water to air was too abrupt.

Solution: Increase humidity immediately. Use a glass lid, plastic wrap, or start a daily misting schedule. You can trim off the crispy leaves; new, better-adapted ones will grow in their place.

Problem: I’m Seeing Pests Like Aphids on the Leaves

Unfortunately, emersed leaves can sometimes attract common houseplant pests.

Solution: Act fast! You can often remove them manually with a Q-tip dipped in water. For a more persistent issue, a very dilute solution of insecticidal soap can be carefully applied with a cloth, ensuring none of it drips into your aquarium water, as it can be harmful to your aquatic inhabitants.

Problem: Growth is Slow or Stalled

If the plant breaks the surface and then just stops, it’s usually one of two things.

Solution: Check your lighting and nutrients. The emersed growth demands more energy, so it may need more intense light or a bump in your fertilizer dosage. Ensure the light is directly hitting the top leaves.

Sustainable and Eco-Friendly Aquascaping with Moneywort

Embracing emersed growth is a fantastic step towards a more natural and balanced aquarium. This approach to sustainable can moneywort grow out of water aquascaping mimics the natural ecosystems where our fish and plants originate.

By creating a self-filtering canopy, you rely less on mechanical filtration and create a more stable environment. This eco-friendly can moneywort grow out of water method reduces your tank’s reliance on frequent, large water changes, conserving water and creating a miniature ecosystem that largely takes care of itself. It’s a win for you, your fish, and the environment.

Frequently Asked Questions About Growing Moneywort Out of Water

Can I grow Moneywort out of the water in an open-top tank?

Yes, you absolutely can, but you must be diligent about humidity. You will likely need to mist the leaves daily, especially in the beginning. Grouping other emergent plants together can also help create a pocket of higher humidity.

Does emersed Moneywort need CO2 injection?

Nope! This is one of the best parts. Once the leaves are in the air, they have access to an unlimited supply of atmospheric CO2. This is why their growth often explodes once they transition, even in a “low-tech” tank without CO2 injection.

How fast will my Moneywort grow once it’s out of the water?

Under ideal conditions (strong light, high humidity, and ample nutrients), the growth can be incredibly fast. You might find yourself needing to trim it every week or two to keep it from taking over!

Will my fish or shrimp try to escape using the emersed plants?

For most fish, this isn’t a concern. However, some notorious jumpers like killifish or hatchetfish might see it as a potential escape route. It’s also wise to be cautious with mystery snails, which can and do leave the water. Know your inhabitants and use a lid if you have known escape artists.

Go On, Break the Surface!

So, can moneywort grow out of water? As you’ve seen, it not only can, but it does so with spectacular results. It’s a simple, rewarding project that adds a whole new dimension to your aquarium.

You’re not just growing a plant; you’re creating a living, breathing piece of art that bridges the gap between the aquatic world and our own. It’s a testament to the incredible adaptability of nature, and it’s waiting to happen right in your living room.

Don’t be afraid to experiment. Let those stems reach for the light, give them the care they need, and watch as your aquarium transforms. Happy scaping!
