How to Propagate Aquarium Plants: Cuttings, Division and Runners (India)

You can propagate most aquarium plants at home by one of four methods: cut and replant stems (Ludwigia, Rotala, bacopa, Anacharis, hornwort), divide the rhizome (Java fern, Anubias, bucephalandra), separate the runners or plantlets (Vallisneria, Amazon sword, crypts, water sprite), or split the clump (Java moss, floating plants). A single bunch bought once can fill a whole tank in a few months, which saves money and gives you plants that are already used to your water. This guide explains each method, shows how to do it step by step, lists which method suits which plant, and covers the light, nutrients and mistakes that decide whether the new plants grow or melt.

Why propagate your own aquarium plants in India?

Aquarium plants are not cheap in India, they are sold in limited varieties and they travel long distances before they reach you. A plant that grows well in your water and your light is worth multiplying: once it has settled in, it will grow with the same temperature, hardness and light that you already have, and you avoid the shock and melt that come with every new purchase. Warm Indian weather helps too, because most tropical plants grow faster at 24-28 C. Propagating at home also keeps pests out, because you only move plants between tanks you already control. If you want to start with a plant that multiplies on its own, see our guide on fastest growing aquarium plants.

How to propagate stem plants by cuttings

Stem plants are the easiest group to multiply. Each stem has nodes, the points where leaves grow, and each node can form roots and side shoots. When a stem grows long, cut the top 8-10 cm with clean scissors, strip the leaves from the lower 2-3 cm and push the bare part into the substrate. The old stem stays in the tank and sends out two new side shoots from the cut point, so one stem becomes three. Plants such as Ludwigia, Rotala, bacopa and water wisteria also form roots from the lowest nodes within 1-2 weeks. See the stem plants guide, bacopa guide and water wisteria guide for plant-specific tips.

1. Choose a healthy stem with firm leaves and at least 12 cm of length.
2. Use clean, sharp scissors and cut about 8-10 cm from the top, just below a node.
3. Remove the leaves from the lower 2-3 cm of the cutting.
4. Push the bare end 2-3 cm into the substrate with tweezers, and plant several cuttings together for a fuller bunch.
5. Leave the old plant in the tank so that it can sprout new side shoots from the cut point.
6. Keep the light on for 6-8 hours, dose a little fertilizer and do not move the cuttings for 2-3 weeks.

Floating stems also grow roots from nodes: Anacharis and hornwort can be cut and left floating, and the pieces will keep growing. See the Anacharis guide and hornwort guide.

Light, carbon and fertilizer for new cuttings

New cuttings have no roots at first, so they take nutrients from the water. Moderate light, a little carbon and a mild all-in-one fertilizer give the strongest start. A tank that is 1-2 feet long grows cuttings well under the Sobo AL-380 (15.5W) (₹1,230), and a nano tank under the Neo Helios Nano S3 Plus (₹1,050). Add a small dose of Sunken Garden Green (₹490) after a water change, and push a Sunken Garden Root Tabs (₹290) beside rooted plants that feed through their roots. See fertilizer guide for amounts, light hours for timing and root tabs guide for dosing.

Planted tank lights by tank size (Fish Bazaar range)

Pick the row that matches your tank length, then choose by plant level: the cheaper full-spectrum lights suit low to medium light plants such as Anubias, Java fern and Cryptocoryne, while the Chihiros WRGB II Pro and B Series are built for red plants, carpets and CO2 tanks. Tank length is the longest side of the glass. Prices are in rupees as listed on Fish Bazaar on 9 October 2026 and can change, so check the product page for the current price and stock.

Chihiros sizes (30, 45, 60, 80, 90, 120) match the tank length in cm. Wattage alone does not decide plant growth, so match the light to your plants and add CO2 and fertilizer only if you want demanding species. Not sure which light fits your tank? See the full aquarium light range or message us with your tank size.

How to divide rhizome plants: Java fern, Anubias and bucephalandra

Rhizome plants grow from a creeping, thick stem that sits on top of the substrate. Once the rhizome has 8-10 leaves, use a clean, sharp blade or scissors to cut it into pieces so that each piece has 3-4 leaves and some roots. Tie each piece to wood or rock, or glue it on, and never bury the rhizome, because it rots. Java fern also grows small baby plants on its leaves, especially on the Windelov and Narrow varieties; leave them until they have 2-3 leaves and roots, then cut them off with a piece of the leaf and attach them to wood or rock. See Java fern guide, Anubias propagation guide and plant holders, weights and glue for tying and gluing tips.

How to propagate Vallisneria, Amazon sword and crypts

These plants send out runners or grow new shoots from the base. Vallisneria sends runners along the substrate with a small plantlet every few cm; wait until the plantlet has 3-4 leaves and white roots, then cut the runner and plant the baby 2-3 cm from the mother. Amazon sword grows a long flower stalk with tiny plantlets; when each plantlet has 3-4 leaves and roots, cut the stalk and plant them. Cryptocoryne spreads by underground runners and offsets, and new plants appear around the mother plant; wait until they have their own roots and leaves, then separate them, and do not move the mother plant, because crypts can melt when disturbed. See the Vallisneria guide, Amazon sword guide and Cryptocoryne guide.

Moss, floating plants and carpets: splitting the clump

Java moss, floating plants and carpet plants multiply by growing outwards. To propagate moss, pull a clump into pieces the size of a coin, spread each piece on a rock or mesh and tie it with thread; see Java moss guide. Floating plants such as duckweed, water lettuce and frogbit form new plants on their own every few days, and you only need to remove the extras so that light still reaches plants below; see floating plants guide and duckweed guide. For carpets, trim the plants and replant the cuttings in bare patches; see carpet plants guide and tissue culture plants.

Tools for propagation

You need only a few tools: sharp scissors, a clean blade for rhizomes, tweezers for planting and a spare bucket or tub for sorting cuttings. A cleaning kit such as the Blue PET 5-in-1 Cleaning Kit (₹899) gives you a plant fork and a scraper for cleaning, and you can use a small clean jar to hold cuttings in tank water until you are ready to plant them. Rinse every tool in tap water before and after use so that algae and pests do not travel between tanks.

Common propagation mistakes

See our guides on how to grow aquarium plants faster and aquarium plant maintenance for a trimming routine, and why plants melt if cuttings or plantlets drop leaves.

What to do with extra plants

A healthy tank soon produces more plants than it needs. Give or swap extras with other hobbyists, share them through local aquarium clubs and groups, or sell them to a local fish shop. Never throw extra aquarium plants into a pond, a lake, a river or a drain, because fast-growing species can escape and harm local waterways. Instead, dry the extras and compost them, or give them away. If you share plants, give a quick dip first; see how to dip and quarantine plants.

Buying a starter plant to propagate in India

The best plants to start with are those that multiply easily: Java fern, Anubias, water wisteria, bacopa and hornwort. Choose a healthy plant with firm leaves, no black patches and clean roots, and give it 2-3 weeks to settle before you cut it. Compare sellers in our guide on where to buy live aquarium plants in India. At the time of writing, Fish Bazaar does not list live plants on the store; we stock the lights, fertilizers, root tabs and tools shown above, and you can message us on WhatsApp for help planning your tank.

हिंदी में संक्षेप: स्टेम वाले पौधों (लुडविजिया, रोटाला, बकोपा) में ऊपर का 8-10 सेमी हिस्सा काटकर निचली पत्तियाँ हटाएँ और मिट्टी में लगाएँ; पुराना तना नई शाखाएँ निकालेगा। जावा फ़र्न और अनुबियास में राइज़ोम को साफ़ ब्लेड से ऐसे काटें कि हर टुकड़े में 3-4 पत्तियाँ रहें, और उसे लकड़ी या पत्थर पर बाँधें, मिट्टी में कभी न दबाएँ। वैलिसनेरिया और स्वॉर्ड के बच्चे पौधों को तब अलग करें जब उनमें 3-4 पत्तियाँ और जड़ें आ जाएँ। मॉस और तैरने वाले पौधों को बस हाथ से अलग करके फैला दें। अतिरिक्त पौधे कभी नदी, तालाब या नाली में न डालें।

Frequently asked questions

How do you propagate aquarium plants?

Use stem cuttings for stem plants, rhizome division for Java fern and Anubias, runners for Vallisneria and swords, and clump splitting for moss and floating plants.

How do you propagate stem plants?

Cut the top 8-10 cm of a healthy stem, strip the lower leaves and plant the cutting in the substrate. The old stem will sprout new side shoots.

How do you propagate Java fern?

Cut the rhizome so that each piece has 3-4 leaves and tie it to wood or rock, or remove baby plantlets from the leaves once they have roots.

How long do cuttings take to root?

Most stem cuttings show white roots in 1-3 weeks, depending on the plant, the light and the temperature.

Can I propagate Anubias by cutting the rhizome?

Yes. Cut the rhizome with a clean blade so that each piece has leaves and roots, then attach each piece to wood or rock.

When should I separate a baby plant from the mother?

Wait until the baby plant has 3-4 leaves and its own roots, then cut the runner or stalk and plant it.

Do I need CO2 to propagate plants?

No. Most easy plants propagate well without CO2 if they get steady light and a little fertilizer, though CO2 speeds up growth.

Why do my cuttings keep floating up?

They are planted too shallow or too loose. Push the bare end 2-3 cm into the substrate and use small stones or a weight for a week.

Can I propagate moss and floating plants?

Yes. Pull moss into small pieces and tie them to wood or rock, and remove extra floating plants as they multiply.

Can I release extra aquarium plants into a pond?

No. Fast-growing aquarium plants can escape and harm local waterways, so give extras away or compost them.
