Why are the lower leaves falling off my Octopus plant?

This is usually caused by a lack of light penetrating to the bottom of the tank, as the dense upper canopy shades the lower stem. Trimming the tops and spacing the stems further apart can help.

Does Pogostemon Stellatus Octopus need CO2 injection?

No, it is an undemanding plant that grows well in low-tech setups without supplemental CO2, though adding carbon dioxide will make it grow much faster and thicker.

How do I trim and propagate this plant?

Simply use aquascaping scissors to cut the stem at your desired height, just above a leaf node. You can then plant the severed top portion directly into the substrate to grow a new plant.

Why are the leaves turning pale or yellow?

Pale or yellowing leaves usually indicate a nutrient deficiency, most commonly iron or nitrogen. Dosing a comprehensive liquid aquarium fertiliser should resolve the issue.

About the Pogostemon Stellatus 'Octopus'

Pogostemon stellatus 'Octopus' is a captivating variant in the planted aquarium hobby. While the wild-type species can be notoriously demanding, requiring intense lighting and carbon dioxide, the 'Octopus' form is incredibly forgiving. Its common name stems from its long, narrow, bright green leaves that curl and twist outward from the central stem, mimicking the tentacles of an octopus. This unique growth pattern creates a beautifully wild, textured look in the background of an aquascape.
