Potting Mix

Premium Aroid Potting Mix for Tropical Houseplants

Aroid potting mix is a chunky, fast-draining soil designed to improve airflow, drainage, and root health for tropical plants like Monstera, Philodendron, Anthurium, and other indoor houseplants. Unlike dense potting soil, chunky mixes prevent compaction and reduce the risk of root rot by keeping oxygen around the roots.

Our Rainbows & Unicorns Aroid Potting Mix is handcrafted for tropical plants — ready to use straight from the bag with no mixing required.

Why Chunky Aroid Soil Works Better

Chunky potting mixes use larger particles like coco chunks, perlite, and organic materials to create air pockets inside the soil. This improves drainage while still holding usable moisture, which helps prevent overwatering and supports stronger root systems.

Designed for Indoor Tropical Plants

This type of soil is ideal for Monstera, Philodendron, Syngonium, Pothos, Alocasia, Anthurium, and Hoya — any tropical houseplant that naturally grows in loose, well-draining environments. A chunky substrate helps replicate those jungle floor conditions indoors.

What’s Inside Rainbows & Unicorns

  • Coco coir chip and pith for moisture control

  • Worm castings and compost for rich organic matter
  • A natural fertilizer with a 6-2-4 ratio for jungle plants
