Why are the lower leaves falling off my Moneywort?

This is typically caused by insufficient light reaching the bottom of the plant. Ensure you are providing at least moderate lighting, and avoid planting the stems too closely together so the light can penetrate down to the lower leaves.

Does Bacopa monnieri need CO2 injection?

No, it is a very hardy plant that can grow perfectly well in low-tech setups without supplemental CO2. However, injecting CO2 will significantly increase its growth rate and result in thicker, more robust stems.

How do I propagate Bacopa in my aquarium?

Propagation is very easy: simply use sharp scissors to cut the top portion of a healthy stem (just above a pair of leaves) and replant the cutting straight into the substrate. It will quickly grow new roots.

Can I grow Moneywort out of the top of my tank?

Yes, Bacopa monnieri transitions very well to emersed growth. If it breaches the water surface in an open-top aquarium, it will continue to grow outwards and may even bloom with small white or pale-purple flowers.

Do I need aquasoil to grow Moneywort?

While aquasoil is beneficial, it is not strictly required. Moneywort takes in a lot of its nutrients directly from the water column, so it can be grown in sand or gravel as long as you provide a good liquid fertiliser.

About the Moneywort

Also commonly known as Water Hyssop, this ubiquitous aquatic plant features fleshy, tear-drop shaped leaves growing in opposite pairs along a thick, upright stem. It is an incredibly adaptable species, capable of thriving in both fully submerged and emersed conditions. Its robust, vertical growth pattern makes it a superb background or midground accent, adding height and structural interest to the aquascape.
