How to Plant Moneywort in Your Aquarium

Moneywort can be planted in aquarium soil, gravel, or substrate. If you choose to plant your moneywort in gravel or sand, it may not take root well, as it tends to float, making it challenging to set or root in your tank.

When you place the young moneywort plant in your tank, you can use rocks, pebbles, or tweezers to keep it in place, especially if you prefer to use sand substrate or a similar gravel material in your aquarium.

When you set your plants in the tank, make sure they are placed at a depth of at least one inch into the sand or substrate and spaced a minimum of two inches apart. If you’re not concerned about securing the plants to the base of your tank, you can have floating plants, which can be fun and protective for your fish and take less preparation and care.

While moneywort plants don’t require much preparation, it is essential to ensure they have enough space to grow to develop, whether they are settled at the bottom of the tank or become floating plants.

If you have more than one tank or a planted aquarium, you can take trimmings from existing plants and replant them to expand your aquatic garden or add them to a pond or similar environment. The more you prune your new plant, the more you encourage it to grow and produce more plants from the original stem.

Potted moneywort is an excellent stem plant for your pond, planted aquarium, and tanks of various sizes and shapes.

If you choose to float your plants, the stems should be carefully separated so they can float freely on the water’s surface. You can also allow some plants to float while others are rooted in the soil or sand, where you can grow new roots.

It’s essential to keep your moneywort spaced adequately in the aquarium, especially if it’s a medium or smaller tank, since this plant is dense and can easily block light, limiting it from reaching the middle and bottom areas of the aquarium.
