Molly's Aroid Mix - Premium Chunky Soilless Potting Mix for Healthy Roots & Fast Drainage

The mix your aroids actually want. Molly’s Aroid Mix is a chunky, soil-free potting blend designed for tropical houseplants that hate soggy roots. This well-aerated mix drains fast, resists compaction, and keeps oxygen flowing—helping plants like Monstera, Philodendron, Alocasia, and Anthurium thrive indoors. Proudly made in the USA, it comes in a resealable, recyclable bag to stay fresh between uses.

Ingredients

Over 20 organic + mineral components, pH-balanced and pest-free.

• Orchid bark (fir), coir fiber & chips
• Expanded clay, perlite, horticultural charcoal
• Canadian sphagnum peat moss
• Worm castings, calcitic & dolomitic limestone
• Beneficial fungi (Rhizophagus irregularis) & bacteria (Bacillus pumilus)
• Natural nutrients + wetting agent

Benefits

• Stops root rot & yellow leaves – Drains quickly, resists compaction, and keeps roots from drowning.
• Cleaner than soil – Gnat-resistant and free of fertilizers, pests, and diseases.
• Builds stronger plants – Mycorrhizae + microbes extend root systems, improve nutrient uptake, and boost natural defenses.
• Lasts longer – Breaks down slowly, meaning fewer repots, less plant stress, and more savings.

FAQs

1. How is Molly’s Aroid Mix different from typical big-box soils?

The difference comes down to structure and water management. Most mass-market soils are made of fine particles that compact quickly, holding excess moisture around roots. While that might work outdoors, it can be disastrous in pots, where poor aeration and waterlogging lead to root rot and declining plant health.

Molly’s Aroid Mix is intentionally built for container plants:

• Drainage without drought – it holds just enough water while letting excess drain away.
• Airflow where roots need it most – large, chunky ingredients create pockets for oxygen and nutrient movement.
• Balanced chemistry – pH levels are optimized for nutrient uptake.
• Cleaner than soil – free of pests, pathogens, and soil-borne diseases.
• Stable structure – supports roots and anchors the plant without suffocating it.

2. Do I need to add anything to Molly’s Aroid Mix?

No additional ingredients are required. The blend is complete on its own, combining organic materials and inert minerals that cover a plant’s essential needs. It includes beneficial fungi and bacteria that extend root systems and improve nutrient absorption—features you won’t find in typical off-the-shelf soil. While you can experiment with mixing in additives, the formula is designed to stand alone as a full-service potting medium.

3. What plants is Molly’s Aroid Mix suited for?

This mix is designed for any indoor plant that benefits from a chunky, well-aerated substrate. That includes many of the most popular tropicals and houseplants—Monstera, Philodendron, Alocasia, Anthurium, Fiddle Leaf Fig, Calathea, Aglaonema, and more. By resisting compaction and encouraging airflow around roots, it supports stronger growth and reduces the stress common to container-grown plants. If you’re unsure about a specific plant, reach out—most indoor species that dislike soggy soil will do well in this mix.

4. How often should I replace the mix?

On average, once a year. That timing aligns with normal repotting cycles as plants outgrow their containers. Molly’s Aroid Mix is made with ingredients that decompose slowly, so it can remain effective for longer periods. When refreshing, don’t worry about removing every piece from the roots—material that clings to the root ball can continue to provide structure and nutrients in the new pot.

5. What’s the best way to water with this mix?

Think “thorough but infrequent.” Most plants in Molly’s Aroid Mix will need water every 1–2 weeks, depending on the plant type, pot size, and your environment. Because the mix drains rapidly, it’s important to let water evenly saturate the pot before flowing through the bottom.

For deeper hydration and healthier root growth, occasional bottom watering is recommended: place the pot in a shallow tray of water for 30–60 minutes. This allows the mix to wick moisture upward, ensuring the entire root zone is rehydrated and encouraging roots to grow downward.

6. How much does one bag cover?

A 5-quart bag goes further than you’d expect:

• Roughly 10–12 small (4") pots
• 6–8 medium (5") pots
• 4–6 larger (6") pots

Because the ingredients decompose slowly, the mix lasts longer than standard soils, making it both a premium and cost-effective option for your plant collection.

We ship from Orange County, and we only ship within the United States. We do not ship to Hawaii / Canada / International. We typically ship on Mondays or Tuesdays to avoid plants being stuck in transit over the weekends, but we may sometimes ship later in the week depending on order volume. With that said, we cannot guarantee or control delivery time. If delivery time is a concern, please opt for upgraded shipping.

We take great care when packaging and preparing your plants for shipment. They'll be shipped either in a nursery pot in soil or sphagnum moss, or shipped bare root wrapped in sphagnum moss or other damp material to retain moisture. We also add poly-fil around the plant for padding, then wrap it in bubble wrap, and finally add packing peanuts for extra cushion to ensure a safe and clean transport.

We also offer local pick-up if you're in the Orange County area.
