Overview

Alternanthera bettzickiana 'Red' is a semi-aquatic stem plant whose green-yellow young foliage deepens to red tones under strong lighting. Best suited to emersed culture in paludariums, terrariums, or bog setups, it can also serve as a temporary submerged display for a few months before older stems soften and need replacing. Regular trimming keeps growth bushy rather than top-heavy.

Care

This is a semi-aquatic stem plant better suited to paludariums, terrariums, or bog-style setups than permanent submersion, since its leaves are not fully aquatic tissue and will eventually break down underwater. It can still be kept as a submerged aquarium accent for a few weeks to a few months before it needs replacing or moving back into emersed conditions. Moderate to high lighting keeps the growth compact and the foliage a dense glossy green rather than leggy and pale.

Planting & trimming

Plant individual stems a couple of inches apart directly into the substrate after removing any foam or packaging from the roots, burying enough of the lower stem to anchor it. Regular trimming of the growing tips encourages bushier side-shoot growth and keeps the plant from becoming top-heavy. In paludariums or terrariums it can also be planted in moist, well-drained soil above the waterline where it will persist far longer than fully submerged.

Fertilizing

A nutrient-rich substrate combined with root tabs supports the root system when grown emersed or as a submerged accent, and a balanced liquid fertilizer helps maintain foliage density in tank form. CO2 injection is not required but noticeably improves growth rate and leaf fullness when used. Pale or leggy stems usually signal insufficient light or a nutrient-poor substrate rather than a specific deficiency.

Propagation

Propagation is by simple stem cuttings: trim a healthy shoot, remove the lower leaves, and replant the cutting directly into substrate or moist soil where it will root within one to two weeks. Multiple cuttings can be grouped together to quickly fill out a midground or background planting.

Problems

Sudden changes in water chemistry or transplanting shock can cause lower leaves to soften and drop, which is a common issue when this plant is moved into fully submerged conditions. Because it is only marginally aquatic, prolonged submersion often leads to gradual decline of older stems even under good care. Algae can accumulate on the slower-growing lower leaves in high-light tanks, so trimming and replanting the healthier tops keeps the display looking fresh.
