FAQs

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

Most mass-market soils cobtain fine particles that compact quickly, holding excess moisture around roots. While that might work outdoors, this leads to poor aeration and waterlogging for potted plants.

Molly’s Aroid Mix is 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.

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: Monsteras, Philodendrons, Alocasias, Anthuriums, Fiddle Leaf Figs, Calatheas, Aglaonemas, and more.

4. How often should I replace the mix?

Once a year on average. That timing aligns with normal repotting cycles as plants outgrow their containers.

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. The mix drains rapidly, so occasional bottom watering is recommended for deeper hydration. 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 covers:

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