In this article, we will outline all you need to know about the roots of these floating freshwater plants. You will learn how big they can grow and tips to ensure this plant thrives in your tank.

How Big Can the Roots of Amazon Frogbit Get?

At maturity, the roots of an Amazon frogbit are about 20 inches (50cm) in the wild, massive, isn’t it? In aquariums, the roots span only about 15 inches. The actual length of your plant’s root depends on several factors.

Does Frogbit Root Grow Fast?

Yes, these roots grow very fast. In fact, most aquarists have likened the speed of growth to that of weeds. With the right conditions, they produce new leaves every two days. After a while, the stem of the mother plant breaks off and forms smaller plants.

Why is the growth rate important? That’s simple, the growth rate and length of the root of a frogbit is a good indicator of the health of this plant. But, there are several factors that must be in place for the plant’s roots to grow as they should. In the next section, we will explore the factors that determine the length of this plant’s roots.

How to Care For Frogbit Root

Every plant owner wants to see their floating roots thriving. One of the ways to determine the health of your frogbit is the length of the roots. But there are several factors affecting the length of your frogbit’s root.

1. Tank Size and Height

Get the right tank capacity and you are on your way to having a healthy plant and roots. We recommend at least 40 liters so that your tank doesn’t become overtaken by this fast-growing plant.

The height of your aquarium also determines how long the roots of this aquarium plant can grow. If you want longer roots, get a high tank or use a pond.

2. Water Parameter

Now that you have a large enough tank, the next step is getting the water conditions these roots enjoy in the wild. Here are some tips for success.

  • Temperature Years of research have shown that this root enjoys normal temperatures. Keep it between 64 -80 F.
  • Hardness – The roots grow faster in soft to moderately hard water around 0-12 dGH.
  • pH – Although this plant root adapts well to any pH, we recommend water with a pH range around 6.0-7.5.

3. Water Nitrate Level

Frogbit roots remove nitrate from the tank. So, it is no surprise that the nitrate levels in their tank affect their growth. In tanks with lower nitrate levels, the roots tend to grow very fast and reach their largest length.

If the nitrate levels in the tank are high, the roots are stunted. So, regulate the amount of nitrate in the water column if you want frogbits with longer roots.

4. Substrate and Water Flow

Finding a substrate for this plant root is not a problem since they float on the surface of the water. You can use any substrate for this root – from gravel to sands, to aquarium soil and more. Ensure that the substrate is enriched. That way, they can absorb the necessary nutrients via the dense roots.

Although frogbits have thick roots, they still prefer water with low currents. Thus, for optimal root growth, ensure slow water flow in your tank otherwise, the roots will keep breaking off.

5. Fish Stocking

We have noticed that some types of freshwater fish affect the length of your roots. Thus, we recommend that you avoid fish that love to eat the roots. Select compatible tank mates.

6. Can I Trim the Roots of My Frogbit?

Yes, you can prune the roots of these aquarium plants from time to time. In fact, we recommend that you trim them. This is because the roots tend to grow long and give your tank a dense jungle-like look. So if you don’t want your aquarium filled with these dense roots, trim them.

Use scissors to clip their roots when they start to get too thick. With time, new rhizomes will sprout from the clipped edges and offer your fish more hiding spots.

7. How Often Should I Trim the Roots of My Frogbit?

Since they grow very fast, you will need to trim the roots of this plant often. If not, the roots will take up all the space in your tank and start to get tangled. We recommend trimming the roots every week, that way, you can maintain a fixed length.

Maintain at least 2-3 inches of root under the cluster of leaves. This ensures that the plant root can still absorb nutrients. Aside from trimming, you may also need to thin out the roots when they grow too large or you notice the leaves start to rot. Thinning them is as simple as removing portions of the roots or removing the entire plant.
