What Makes Rainbows & Unicorns Potting Mix Different
A high-performance aroid soil blend built to support healthy roots in Monstera, Philodendron, Anthurium, and other houseplants.
Large bark and chunky ingredients prevent soil compaction and create the loose structure that tropical aroids need to grow strong roots.
The mix drains quickly so roots never sit in soggy soil, reducing the risk of root rot and overwatering.
Air pockets between ingredients allow oxygen to reach the root system, which supports faster growth and healthier plants.

Best Soil for Aroids
Aroids are tropical plants that naturally grow in loose forest substrates where roots have constant access to oxygen, moisture, and organic material. In dense potting soil, aroid roots can struggle because water sits around the root zone and airflow is limited.
A chunky aroid potting mix solves this problem by creating air pockets between ingredients like bark, mineral drainage materials, and organic components. These air pockets allow oxygen to reach the roots while excess water drains quickly away.
Rainbows & Unicorns Aroid Potting Mix was developed specifically for aroids that require excellent drainage and strong root aeration. The chunky particle structure helps prevent soil compaction while maintaining balanced moisture around the roots.
This type of soil structure works well for many tropical aroids, including:
• Monstera
• Philodendron
• Anthurium
• Alocasia
• Rhaphidophora
• Scindapsus
If you’re growing aroids indoors, these guides explain how soil structure affects root health and plant growth:
Learn More About Aroid Soil
Aroids like Monstera, Philodendron, Anthurium, and Alocasia grow best in chunky, well-aerated potting mixes that allow oxygen to reach the root system while draining excess water quickly. Dense soil can suffocate roots and lead to root rot, which is why many collectors switch to structured aroid substrates.
Rainbows & Unicorns Aroid Potting Mix was designed specifically for tropical aroids that require airflow, drainage, and stable root support. The chunky structure helps prevent soil compaction while allowing roots to expand and grow naturally.
