Molly's Aroid Mix - Premium Tropical Plant Soilless Potting Mix

Drains fast: the chunky texture lets water move through quickly and resists compaction, so roots aren't left sitting in water. That lowers the risk of overwatering.

Made without soil: it doesn't bring garden soil into your pots.

Supports root development: the mix contains mycorrhizae, which colonize the roots and help them reach water and nutrients in more of the pot.

Slow to break down: the clay pebbles hold their shape and the bark breaks down slowly, so the mix stays open between repottings.

Ingredients, largest first: coco chips, Douglas fir and pine bark, a peat-based growing mix with mycorrhizae, expanded clay pebbles (LECA), worm castings, coco coir and biochar.

Peat: low peat content. The base of the mix is coco chips and bark.

Aroids such as Monstera, Philodendron and Anthurium grow as climbers in the wild, with roots that hold onto bark and sit in moving air. In a pot they do best in a chunky mix that drains quickly and doesn't pack down. Dense potting soil holds more water and less air around the roots.

Molly's Aroid Mix is built for that. Coco chips and two kinds of bark give it a coarse, open structure, clay pebbles keep the air pockets from collapsing, and a smaller share of peat-based mix, coir and worm castings holds moisture between waterings.

What's in the bag

• Coco chips: the largest ingredient. Chunky pieces of coconut husk that hold some water and keep the mix open.
• Douglas fir and pine bark: coarse bark for structure and air space.
• Peat-based growing mix with mycorrhizae: holds moisture. The mycorrhizal fungi colonize roots and support root development.
• Expanded clay pebbles (LECA): hard pellets that hold their shape and keep air pockets open.
• Worm castings: a small organic fraction.
• Coco coir: fine coconut fiber that evens out moisture.
• Biochar: a small amount.

Low-peat and soil-free. The mix has some nutrients but isn't a fertilizer.

Plants this is for

• Monstera: deliciosa, adansonii, Thai Constellation, Albo.
• Philodendron, Pothos, Scindapsus, Epipremnum: climbing and trailing aroids.
• Anthurium, Alocasia, Syngonium, Aglaonema: tropical foliage aroids.
• Also suited to: Calathea and other prayer plants, Peace Lily, ZZ plant, snake plant, Hoya, Fiddle Leaf Fig and palms.

Not for: succulents and cacti (use Molly's Succulent Mix) or orchids (use Molly's Orchid Mix).

Repotting

1. Choose a pot 1 to 2 inches wider than the current root ball, with drainage holes.
2. Ease the plant out and shake off loose old soil.
3. Add about an inch of mix to the bottom, set the plant at the same depth as before and fill in around the roots. Tap the pot to settle the mix; don't press it down.
4. Water thoroughly once and let it drain. Water again when the top inch is dry.

Watering

Most aroids in this mix need water every 7 to 14 days indoors, depending on light, temperature and pot size. Check the top inch with a finger first: the mix dries from the top down, so a dry surface doesn't always mean a dry root zone. Water evenly over the whole surface and empty the saucer.

Sizing and coverage

Filling empty pots, one 5 dry quart (5.5 L) bag fills about 8 four-inch pots, 4 to 5 five-inch pots, or 2 to 3 six-inch pots. When you repot a plant that already has a root ball, the same bag covers about 10 to 12 four-inch, 6 to 8 five-inch, or 4 to 6 six-inch pots. Larger bags scale with volume.
