Plant Profile
Meet Microcarpaea Minima Merrill is rare and sought-after aquatic stem plant with ultra-fine, needle-like leaves in opposing pairs along slender stems. It's got serious lookalike energy with hobby favorites like Pearl Weed and Mayaca fluviatilis, minus the common-plant reputation. Extremely versatile in aquascaping, Microcarpaea Minima can be kept low as a dense foreground carpet through routine pruning, or left untrimmed to form soft, cloud-like background hedges that can be sculpted into rounded bushes and Dutch-style streets.
Tissue Culture cups ensure your aquascape gets a super clean starting point. Lab‑grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go‑to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.
Key Features & Benefits
- Rare and delicate fine-leafed foliage adds soft texture, movement, and scale to both nano tanks and large aquascapes.
- Versatile growth habit easily trained into a dense foreground carpet or sculpted into midground and background bushes.
Care & Planting Instructions
-
Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions. *Microcarpaea stems are exceptionally slender, so handle with care during preparation.
- Use fine-tip pinsettes to plant small stem clusters 1 inch apart into aquarium soil.
- Provide medium-to-high lighting and consistent fertilization; while adaptable, adding pressurized CO2 yields significantly denser branching and faster horizontal spreading.
- Maintain stable water parameters and avoid sudden parameter swings to prevent stem melting or rotting.
- Trim main stem tops with curved scissors to shape into desired forms, and replant trimmings directly into substrate to easily propagate and expand coverage. Read our trimming & propagation guide for details.

Frequently Asked Questions
1. Why are the lower leaves falling off my stem plants?
Lower leaf loss (leggy stems) usually occurs when lighting cannot reach the bottom of the plant due to overcrowding or shading from larger plants. Spacing individual stems slightly apart during initial planting and maintaining strong light penetration will keep lower leaves healthy.
2. How do I keep Microcarpaea Minima Merrill growing low like a carpet?
To keep Microcarpaea Minima growing horizontally as a carpet, provide high light intensity, pressurized CO2, and routinely trim the top of vertical shoots. Trimming encourages the stems to branch laterally along the substrate.
3. How do I prepare Microcarpaea Minima Merrill Aquatic Farmer Tissue Culture before planting?
Carefully remove the gel from the roots by washing the plant in a bowl of room-temperature water or gently rinsing it under a tap. Once the gel is removed, separate the dense cluster into smaller clumps or individual stem bundles and plant them into substrate using fine pinsettes.
