Preparation

• Acclimatization: Before planting, acclimatize your plants to the water conditions of your aquarium to reduce shock. This can be done by floating them in their bags in the aquarium water for 15-30 minutes.
• Trimming: Trim any dead or damaged leaves and roots. For stem plants, cutting the lower leaves can help prevent rotting once planted and encourage root growth.

Substrate Planting

• Rooted Plants: For plants like Cryptocoryne or Echinodorus, make a small hole in the substrate using your fingers or planting tweezers. Insert the plant into the hole and gently cover the roots with substrate, ensuring the crown (where the roots meet the stem) is not buried to prevent rot.
• Stem Plants: Plant stem plants in small groups to create a bushy effect. Insert the stems into the substrate, leaving enough space between them to allow light and water circulation, which promotes healthier growth.

Attaching to Hardscape

• Rhizome Plants: For plants like Anubias and Bucephalandra that grow on hardscape, use fishing line, cotton thread, or super glue to attach them to rocks or driftwood. Ensure the rhizome (the horizontal stem from which leaves grow) is not buried in the substrate to prevent rot.

Positioning

• Place mid-ground plants strategically to create depth and interest. They should be visible but not overpower the foreground plants or be overshadowed by the background plants.

Maintenance Tips

Pruning

• Regular pruning is necessary to keep mid-ground plants in shape and prevent them from overshadowing others. For stem plants, trim the tops and replant the cuttings if you want to propagate them. For rosette plants, remove old or yellowing leaves at the base.

Cleaning

• Gently clean the leaves of mid-ground plants during water changes to remove algae or debris. Use a soft brush or sponge for delicate plants to avoid damage.

Fertilization

• Mid-ground plants benefit from both substrate fertilizers, especially for root feeders, and liquid fertilizers for water column feeders. Follow the recommended dosages based on your plant load and nutrient levels.

Lighting

• Ensure your mid-ground plants receive adequate light without being shaded out by taller plants or decorations. Adjust the positioning of lights or plants as necessary to achieve even light distribution.

Water Parameters

• Regularly test water parameters (pH, hardness, nutrients) to ensure they remain within the ideal range for your plants. Adjustments to water chemistry should be made gradually to avoid stressing the plants.

CO2 Supplementation

• While not always necessary, adding CO2 can significantly boost the growth and vibrancy of your mid-ground plants. If you choose to use CO2, ensure it is evenly distributed and the levels are carefully monitored to avoid harming your aquatic life.
