If you’ve noticed some leaves turning yellow, becoming transparent, or even melting away after planting, don’t panic.

In most cases, this is completely normal.

What Is Plant Melt?

Many aquarium plants are grown above water (emersed) by commercial nurseries. Once planted underwater, the plant must adapt to its new environment by producing a different set of leaves designed for submerged growth.

At The Wet Leaf, we have some submerged, but also we like to keep many of our Tropica Aquarium Plants growing emersed  because it makes them easier to ship less susceptible to longer shipping times and temperatures.

During this transition, older leaves may

• Turn yellow or brown

• Become transparent

• Develop holes

• Gradually melt away

While it can look alarming, it’s often a sign that the plant is adjusting—not dying.

What Should You Do?

✔ Leave healthy roots undisturbed

✔ Remove leaves that are completely melted or decaying

✔ Maintain consistent lighting and fertilization

✔ Be patient

Most plants begin producing new underwater growth within a few weeks.

When Should You Be Concerned?

You may want to investigate further if:

• The entire plant turns mushy, including the crown or stem.

• No new growth appears after several weeks.

• Multiple species are declining at the same time.

• Algae is heavily covering new growth

In these cases, lighting, nutrients, CO₂, or water parameters may need adjustment.

A Few Plants That Commonly Melt

Some species are particularly known for melting after planting:

• Cryptocoryne species (“Crypt Melt”)

• Certain swords

• Stem plants transitioning from emersed growth

• Some carpeting plants

Many of these plants recover beautifully once established. And with Good growing conditions right off the start, you may not even see plant melt. 

The Best Sign of Success

Don’t focus on the old leaves.

Look for new leaves.

Even a single healthy new shoot means the plant is adapting and moving in the right direction.

If you’re unsure whether what you’re seeing is normal, simply get in touch with us with a photo of your aquarium. We’re always happy to help.
