  • Bottom layer: Nutrient-rich soil or substrate (if desired).
  • Middle layer: Gravel for drainage.
  • Top layer: Decorative gravel to enhance appearance.

Selecting Suitable Plants

Choosing the right plants is critical when growing in aquarium gravel. Certain plant types thrive better in gravel than others.

  • Best Plant Types for Gravel:
  • Rooted plants (e.g., Anubias, Cryptocoryne, and Java Fern): These plants can establish roots in gravel.
  • Floating plants (e.g., Duckweed, Water Lettuce): Suitable for those who prefer minimal substrate interaction.
  • Avoid:
  • Heavy-rooted plants (e.g., certain larger species) that require deeper substrate for stability.

Planting Techniques in Gravel

Correct planting techniques ensure that the plants can establish themselves effectively in the gravel medium.

  • Spacing:
  • Provide enough space between plants to allow for growth.
  • Recommended spacing varies by plant size but generally ranges from 2 to 4 inches apart.
  • Planting Depth:
  • Insert the roots gently into the gravel, ensuring the crown of the plant is above the substrate.
  • Use a planting tool or your fingers to create a small hole, place the roots, and cover lightly with gravel.
