Planting and Growing Dwarf Baby Tears

How to Plant Dwarf Baby Tears

Planting Dwarf Baby Tears in your aquarium requires patience and attention to detail due to their delicate nature. Here’s a step-by-step guide to help you plant them:

  1. Prepare the Plant: Dwarf Baby Tears typically come in pots or as tissue cultures. Carefully remove them from the pot and wash off any attached gel or rock wool. This step ensures that you get rid of any possible contaminants that could affect your aquarium’s health.
  2. Divide the Plant: Dwarf Baby Tears grow more efficiently when planted in small portions. After washing, gently divide the plant into several small portions or clumps.
  3. Prepare the Tank: Fill your aquarium with a nutrient-rich substrate, making sure it’s around 2-3 inches deep. Slope the substrate higher at the back to create depth.
  4. Plant Dwarf Baby Tears: Use tweezers to plant each small clump into the substrate. Ensure each portion is spaced about 1-2 inches apart to allow room for growth and spreading. Push each clump into the substrate until only the top of the plant is visible.
  5. Add Water: Slowly add water into the tank until it is just above the level of the substrate. Be careful not to dislodge the newly planted plants.
  6. Lighting and CO2: Once planted, ensure the tank has high intensity, full-spectrum lighting and adequate CO2 supplementation. These are crucial for the growth.
  7. Maintenance: Trim the plant regularly to promote horizontal growth and a lush carpet look. Keep an eye on CO2 and nutrient levels to ensure they are within optimal range.

Growing Dwarf Baby Tears on Driftwood and Rock

Growing on driftwood and rocks in your aquarium can create an impressive and natural-looking aquascape. Here are the steps to do it:

  1. Prepare the Plant: As with planting in substrate, you need to start by removing the Dwarf Baby Tears from their original container. Carefully clean off any rock wool or gel that may be stuck to the roots.
  2. Prepare the Driftwood/Rock: Make sure your chosen driftwood or rock is clean and safe for use in your aquarium. If you’re using driftwood, it’s often recommended to soak or boil it first to remove tannins and any possible hitchhikers.
  3. Attach the Plant: Cut a piece of fishing line, cotton thread, or use a plant-specific glue. Place the plant on the driftwood or rock and gently but securely tie or glue it down. If you’re tying the plant, make sure not to tie it too tightly as this can damage the plant. The thread or line should just be secure enough to hold the plant in place.
  4. Place in the Tank: Carefully place the rock or driftwood with the attached plant into your tank. Make sure it’s secure and won’t easily topple over.
  5. Provide Care: Provide your plant with ample lighting, CO2, and nutrients for healthy growth. High intensity, full-spectrum lighting is important for growth and maintaining the vibrant green color.
  6. Wait: Over time: The roots of the Dwarf Baby Tears will attach themselves naturally to the rock or driftwood. If you used a biodegradable thread, it would decompose naturally. If you used fishing line, you might want to remove it once the plant is firmly attached.

The Dry Start Method

The Dry Start Method (DSM) is a popular technique used in the aquascaping hobby, especially when working with carpeting plants like Dwarf Baby Tears. It involves growing plants emersed (partially out of water) before filling the tank with water.

This method can help establish a healthy, thick carpet more easily and quickly compared to starting with a fully submerged setup. Here’s a step-by-step guide to using the Dry Start Method with Dwarf Baby Tears:

  1. Prepare the Tank and Substrate: Start by laying a nutrient-rich substrate in your clean aquarium. Slope it higher at the back to give an illusion of depth.
  2. Plant Dwarf Baby Tears: Next, plant small clumps of Dwarf Baby Tears into the substrate, similar to the traditional planting method. Make sure they are spaced apart to allow for growth and spreading.
  3. Moisture: Add water to the tank, but only until it reaches the top of the substrate. The goal is to keep the environment humid, not submerged.
  4. Cover the Tank: Cover the aquarium with a lid or plastic wrap to maintain high humidity inside. This mimics the wet environment these plants would naturally grow in, encouraging growth and root development.
  5. Lighting: Provide the tank with high intensity, full-spectrum lighting for about 10-12 hours each day to support photosynthesis.
  6. Maintenance: Monitor the tank daily to ensure the substrate remains moist. It’s also crucial to allow some fresh air into the tank regularly to prevent mold growth. You can do this by partially lifting the cover for a few minutes each day.
  7. Flood the Tank: After several weeks, when the Dwarf Baby Tears have formed a solid carpet and the roots have established themselves firmly in the substrate, you can gradually add water to the tank until it is filled. At this point, you should also start providing CO2 and begin regular tank maintenance.

Growing Dwarf Baby Tears Emersed

Growing Dwarf Baby Tears emersed, or partially out of water, can be an effective way to establish a dense carpet before flooding your aquarium, often accomplished using the Dry Start Method (DSM). Here’s how to grow Dwarf Baby Tears emersed:

  1. Prepare Your Tank: Add a layer of nutrient-rich substrate to your aquarium. This layer should be around 2-3 inches deep to allow for proper root growth.
  2. Plant Dwarf Baby Tears: Plant small clumps of Dwarf Baby Tears into the substrate, spacing them about 1-2 inches apart. This will encourage the plants to spread and form a carpet.
  3. Add Water: Add water to the tank until it reaches just above the substrate level. You’re not looking to submerge the plants fully; you’re aiming for a humid, swamp-like environment.
  4. Cover the Tank: Cover the aquarium with a lid or plastic wrap to maintain the high humidity levels necessary for the emersed growth of Dwarf Baby Tears. The cover will also help prevent the water from evaporating quickly.
  5. Provide Adequate Lighting: Dwarf Baby Tears require high-intensity lighting for optimal growth. Ensure they receive 10-12 hours of bright, full-spectrum light each day.
  6. Maintain: Monitor the tank daily. The substrate should stay moist, but not waterlogged. You might need to mist the plants occasionally if they begin to dry out.
  7. Allow for Ventilation: Even though you need a high humidity environment, it’s essential to allow fresh air to circulate within the tank to prevent mold or mildew growth. Simply lift the cover for a few minutes each day to exchange air.
  8. Time to Flood: Once you see that the Dwarf Baby Tears have formed a dense carpet and the roots are well-established in the substrate, which can take several weeks to a few months, gradually fill the tank with water. Start CO2 injection and regular tank maintenance at this point.

Maintenance and Care of Dwarf Baby Tears


Trimming Dwarf Baby Tears is a crucial part of their maintenance and helps ensure a dense, lush carpeting effect. Here are the steps to follow:

  • Observe Growth: Allow Dwarf Baby Tears to grow until they reach a height of around 1-1.5 inches. Watch for any signs of vertical shoots, which can lead to a less dense carpet.
  • Choose Tools: Use a pair of sharp aqua scaping scissors for trimming. Curved scissors can be particularly helpful in reaching different areas of the carpet without disturbing other elements in the tank.
  • Trim Regularly: Regular trimming helps promote lateral growth and keeps the carpet dense. Aim to trim every 2-3 weeks or when the plants reach the desired height.
  • Trimming Technique: Cut the plants at an angle to maintain a natural, uneven look that mimics nature. Avoid cutting too close to the substrate to prevent damaging the root system.
  • Cleaning Up: After trimming, make sure to remove the cuttings from the water to prevent any decomposition, which could affect water quality. A small net can be useful for this.

Dwarf Baby Tears Carpet Growth Time

The time it takes for the plant to form a complete carpet in your aquarium can vary greatly depending on several factors including the light intensity, CO2 levels, nutrient availability, and the initial amount of plant material used.

On average, under optimal conditions with high light, plenty of CO2, and nutrient-rich substrate, They can start to form a decent carpet in about 4-6 weeks. However, achieving a full, lush carpet could take several months.

Using the Dry Start Method, where the plants are grown emersed, can speed up this process, and a full carpet can often be achieved in a similar timeframe, before the tank is flooded. Keep in mind, slower growth isn’t necessarily a bad thing.

It allows more time for the roots to establish and can result in a healthier, more robust carpet in the long term. Patience is key when growing a carpet of Dwarf Baby Tears. It may take time, but the end result is worth the wait.


  • Observe Growth: Allow the Tears to grow and establish a healthy carpet.
  • Select a Clump: Choose a dense clump of Tears for propagation.
  • Cut: Using a pair of aqua scaping scissors, cut a small portion from the selected clump.
  • Replant: Take the cut portion and plant it into the substrate in another part of the tank.
  • Care: Ensure that the newly planted portion gets enough light, CO2, and nutrients for healthy growth.

Remember, successful propagation depends on maintaining ideal conditions in the tank. Regular monitoring and maintenance are key to healthy growth and propagation of Dwarf Baby Tears. dwarf-baby-tears-Propagating
