Rinse and divide tissue-culture plants before planting

Tropica’s 1-2-Grow cups contain young plants for dividing into portions, not a finished planting to tip straight into an aquarium.¹

1. Decide where it belongs before opening

Read the species label first. Anubias barteri nana and Eleocharis pusilla 'Mini' both come in tissue-culture cups, but their destinations differ: Tropica recommends stone or wood for the Anubias, while the Eleocharis is a foreground carpeting plant. The grower also rates the latter's light and CO2 demand as medium, versus low for the Anubias. A shared package is not a shared care plan.³⁴

Keep the cup sealed until you are ready to work. That is Dennerle Plants' handling instruction for its Plantit range. Our preparation suggestion: set out tweezers, a small work surface and your planting plan first, so you are not hunting for tools with the plant already out of its container.²

2. Remove the growing medium gently

Ease the plant material out, then rinse away the liquid or gel around it. Dennerle specifies lukewarm water and a gentle touch; Tropica likewise instructs users to rinse off the medium under the tap. Follow the cup's own directions. The job is to remove the growing medium, not scrub the small plants clean with force.¹²

3. Divide to suit the planting

Tropica suggests six to eight portions for small foreground plants, planted with tweezers—not a rule for every species. Its Eleocharis guidance calls for small portions spaced across the planting area. Let the carpet grow rather than installing one solid plug.¹⁴

Anubias needs a different finish. Attach it to suitable stone or wood rather than treating it like a grass tuft. Tropica warns against burying its rhizome—the thick stem from which the plant grows—because it can rot. Choose the planting method from the species information, even when the cup's general instructions show tweezers pushing plants into substrate.³

4. If a portion floats up

If a substrate-planted portion keeps floating up, Dennerle suggests checking whether it is too large and dividing it further. For a new setup, the grower recommends planting with little or no water, then filling slowly without disturbing the substrate. That is a setup technique, not a reason to drain an occupied tank.²

What the sealed cup promises

Tropica guarantees its own 1-2-Grow range is free of snails, algae and pesticides. That manufacturer statement is not an independent test of every tissue-culture product, nor a promise that an aquarium will remain algae-free after planting.¹
