Stop Suffocating Your Tropical Plants

If your Monstera's roots are turning to mush or your Philodendron sits in soggy soil for days after watering, regular potting soil is the problem. It's too dense, holds too much water, and basically suffocates tropical plant roots that evolved to grow on trees—not buried underground.

Aroids are epiphytes in nature. Monsteras, Philodendrons, Pothos, Anthuriums—they all grow on tree bark in the rainforest with their roots exposed to air. They're designed to grab moisture and nutrients from what washes over them, then dry out quickly. Dense potting soil works against everything these plants need.

This mix recreates that airy rainforest environment. Chunky orchid bark creates natural drainage channels and air pockets. Ancient Soil delivers the nutrients and beneficial microbes. And the whole structure stays loose and fluffy—giving your plant's roots what they've been missing.

Why Aroids Need Different Soil

Most houseplants grow in actual soil. Aroids? Not so much. In their natural habitat, they're climbing up trees or sprawling across the forest floor with roots that barely touch anything solid. The roots are covered in velamen—a spongy tissue that soaks up moisture from rain and humidity, then dries out fast.

When you stick an aroid in regular potting soil, you're forcing it to live in conditions it never evolved for. The dense mix holds water too long. The roots can't breathe. Root rot sets in. The plant starts dropping leaves, yellowing, looking generally sad.

Aroid Mix solves this by using chunky components that create space. Water drains through quickly. Air circulates around the roots. But there's still enough moisture retention to keep plants hydrated between waterings. It's the balance these plants need.

What's Actually In This Mix

Chunky Orchid Bark

  • Creates natural air channels throughout the mix
  • Allows water to drain quickly preventing root rot
  • Holds moisture in the bark itself for slow release
  • Breaks down slowly, maintaining structure for years
  • Mimics the tree bark aroids grow on naturally

The bark pieces are substantial—not the tiny shredded stuff you find in cheap mixes. Real chunks that create lasting structure. Water flows through, air circulates, but the bark itself holds enough moisture to keep roots from completely drying out between waterings.

Ancient Soil

  • Premium worm castings loaded with nutrients
  • Over 250 species of beneficial bacteria and fungi
  • Natural growth hormones and enzymes
  • Improves nutrient uptake and plant immunity
  • Slow-release feeding that lasts for months

This is where the nutrition comes from. Ancient Soil is basically a probiotic for your plants—living biology that colonizes the root zone, breaks down organic matter, and helps plants access nutrients. It's the same premium worm castings we use in all our products, just mixed into the perfect ratio for aroids.

Perlite

  • Those white pebbles you see throughout the mix
  • Keeps the mix light and prevents compaction
  • Creates additional drainage pathways
  • Doesn't break down over time
  • Ensures water never pools in the pot

Perlite is volcanic glass that's been heated until it pops like popcorn. It's incredibly lightweight and doesn't hold water—just ensures the mix stays airy and never gets dense. Even after years, the structure remains loose because perlite doesn't decompose.

How to Repot with Aroid Mix

Step-by-Step Repotting Process

Repotting aroids is straightforward, but there are a few tricks to make it go smoothly.

Remove Old Soil

Gently remove your plant from its pot. Massage the root ball and shake off as much old soil as possible. You want to expose the roots without damaging them. Trim away any mushy or dead roots with clean scissors.

Choose the Right Pot

Go up one pot size (2 inches larger diameter). Make sure it has drainage holes. Aroids in this chunky mix need to drain freely—no holes means guaranteed root rot no matter what soil you use.

Fill and Position

Add a layer of Aroid Mix to the bottom. Position your plant at the same depth it was growing before. Fill around the roots with more mix, gently pressing to eliminate major air pockets but not packing it tight.

Water Thoroughly

Water until it runs out the drainage holes. This settles the mix around roots and ensures good contact. Let it drain completely—never let the pot sit in standing water.

What Makes This Better Than Regular Potting Soil

The Root Rot Problem

Root rot is the number one killer of Monsteras and Philodendrons. It happens when roots sit in waterlogged soil without oxygen. The roots literally suffocate, then bacterial and fungal pathogens move in to decompose the dead tissue. By the time you see symptoms above ground—yellowing leaves, wilting, brown spots—the rot is often advanced.

Regular potting soil stays wet too long for aroids. Even with drainage holes, the dense mix holds moisture in the root zone for days. Aroid Mix solves this by draining quickly while still providing moisture. The chunky texture means roots get air circulation even when the mix is damp.

Root Development

Aroids put out two types of roots in nature—aerial roots that climb and absorb moisture from air, and anchoring roots that grab onto bark. Both types need air flow. In dense potting soil, roots can't spread naturally. They circle the pot looking for oxygen, getting root-bound faster.

In Aroid Mix, roots spread throughout the pot easily. They branch more because there's air available. You'll see faster root development and healthier overall root systems—which translates directly to more vigorous top growth.

pH and Nutrient Availability

The mix is slightly acidic (around 6.0-6.5 pH), which is what tropical aroids prefer. Ancient Soil provides slow-release nutrition, but the chunky structure also means you can supplement with liquid fertilizer without worrying about salt buildup the way you would in dense soil.

Watering adjustment: This mix drains faster than regular potting soil, so you'll likely water more frequently—but with less volume each time. Stick your finger in 2-3 inches. If it's dry, water thoroughly. The top will dry out quickly, but there's still moisture deeper in the pot where roots need it.

Perfect For These Plants

Monsteras

Every Monstera variety thrives in this mix. Deliciosa, Adansonii (Swiss cheese vine), those expensive variegated types—they all have the same chunky, airy soil preference. The orchid bark mimics the tree bark they naturally climb, and the fast drainage prevents the root rot that Monsteras are prone to when overwatered.

Philodendrons

From Brasil to Pink Princess to Birkin to climbing varieties like Micans—all Philodendrons are aroids that need this type of mix. They're actually closely related to Monsteras and have identical soil requirements. If your Philodendron has been growing slowly or dropping leaves, switching to Aroid Mix often kickstarts new growth within weeks.

Pothos

Golden Pothos, Marble Queen, Neon, Njoy—all of them. Pothos are nearly indestructible, but they grow even faster and produce bigger leaves in Aroid Mix. The improved root aeration means more vigorous vining and better variegation on variegated types.

Anthuriums

Both the flowering types (with those waxy red or pink spathes) and the foliage types (like Clarinervium with the dramatic veined leaves). Anthuriums are particularly sensitive to overwatering and absolutely need the quick drainage this mix provides. They'll reward you with more blooms or bigger leaves.

Alocasias

Those dramatic elephant ear plants with the stunning foliage. Alocasias are notoriously fussy about watering—too much causes rot, too little makes them drop leaves. Aroid Mix makes watering easier because it's more forgiving. The soil doesn't stay soggy, so you have a wider window where moisture levels are acceptable.

Also Great For These Plants

  • Orchids: It's got orchid bark in it—of course orchids love this mix
  • Hoyas: Semi-succulents that need excellent drainage
  • Peperomias: Hate wet feet, thrive in chunky mixes
  • Syngoniums: Arrow plants with the same aroid needs
  • String of Hearts/Turtles: Trailing plants that need air flow to roots
  • Begonias: Many varieties prefer the fast drainage
  • Any plant you've accidentally overwatered to death before

Watering Changes You Need to Know

You'll water differently with Aroid Mix compared to regular potting soil. The chunky texture means water flows through quickly—which is the whole point. But it also means you need to adjust your routine.

The top layer will dry out faster than you're used to. That's normal and fine. The bark and Ancient Soil hold moisture deeper in the pot where the roots actually are. Don't water just because the surface looks dry—check 2-3 inches down with your finger or a moisture meter.

When you do water, water thoroughly. Let it run out the drainage holes. This ensures even moisture distribution through the chunky mix. Then let it drain completely before putting the pot back on its saucer or in its cover pot.

Most people end up watering more frequently than they did with regular soil, but they're using less water each time. Instead of drenching a dense mix once a week, you might water this mix twice a week with less volume. The plant gets consistent moisture without ever sitting in soggy conditions.

Pro tip: A moisture meter takes the guesswork out of watering chunky mixes. Stick it down to root level. Water when it reads in the dry zone. This prevents both overwatering and underwatering while you're adjusting to the new soil.

When to Repot

Spring is the best time for repotting—when plants are actively growing and will recover quickly. But if your plant is severely root-bound or showing signs of root rot, repot immediately regardless of season. A struggling plant won't get better in the wrong soil.

Signs you need to repot:

  • Roots growing out of drainage holes
  • Water sits on top instead of draining
  • Stunted new growth or smaller leaves
  • Plant tips over because it's top-heavy
  • You're watering constantly and it still looks thirsty
  • Yellowing leaves with brown mushy spots (root rot)
  • It's been 2+ years in the same soil

How Much You Need

Coverage depends on pot size:

  • 3-quart bag: Perfect for 2-3 small plants in 4-6 inch pots, or 1 larger plant in an 8-10 inch pot
  • 8-quart bag: Handles 1 large Monstera or Philodendron in a 12-14 inch pot, or multiple medium-sized plants

If you're repotting a really large specimen (16+ inch pot), you'll want multiple bags or the larger size. Better to have leftover than to run short halfway through repotting.

Will This Actually Help My Plant?

Here's the honest answer: if your plant has been struggling because of soil issues—root rot, slow growth, yellowing leaves from overwatering—switching to Aroid Mix usually turns things around fast. Within a few weeks, you'll typically see new growth starting, healthier leaf color, and more vigorous overall growth.

If your plant has problems that aren't soil-related (insufficient light, pest infestation, extreme temperature stress), new soil alone won't fix everything. But good soil removes one major obstacle and lets you focus on addressing other issues.

We've had customers send photos of half-dead Monsteras that suddenly pushed out four new leaves at once after repotting. The reason? Healthy roots equal healthy plants. When roots can breathe and spread naturally, everything above ground improves.

Why We Made This Mix

As plant collectors ourselves, we got tired of watching expensive aroids struggle in regular potting soil. We knew these plants needed something different—looser, chunkier, more like their natural habitat. But the commercial aroid mixes available were either prohibitively expensive or filled with questionable components.

So we formulated our own using the same philosophy as our other products: give plants what they actually need in nature. Premium orchid bark for structure and drainage. Ancient Soil for nutrition and beneficial microbes. Perlite to keep everything airy. No fillers, no mystery ingredients, just what works.

We use this mix on our own Monsteras and Philodendrons. If it wasn't producing results, we wouldn't sell it.

Common Questions About Aroid Mix

What plants is Aroid Mix best for?

Aroid Mix is perfect for Monsteras, Philodendrons, Pothos, Anthuriums, Alocasias, and any tropical aroid houseplants. These plants naturally grow on the rainforest floor with chunky, well-draining soil, which is exactly what this mix provides.

What makes Aroid Mix different from regular potting soil?

Aroid Mix contains chunky orchid bark that creates air pockets for root aeration, unlike dense regular potting soil. This mimics the natural rainforest environment where aroids grow. The mix drains quickly while retaining just enough moisture, preventing root rot while keeping roots happy.

How often should I repot my plants with Aroid Mix?

Most aroids need repotting every 1-2 years, typically in spring when growth is most active. Signs your plant needs repotting include roots growing out of drainage holes, water sitting on top of soil instead of draining, or stunted new growth.

Does Aroid Mix contain fertilizer?

Yes! Aroid Mix includes our Ancient Soil, which is packed with beneficial microbes and nutrients from worm castings. This provides slow-release nutrition to support new growth. However, we still recommend supplementing with liquid fertilizer during the growing season for optimal results.

Will this mix work for other houseplants besides aroids?

Absolutely! While formulated specifically for aroids, this mix works wonderfully for any houseplants that prefer well-draining soil, including orchids, hoyas, peperomias, and succulents. It's particularly great for plants prone to root rot.

How much Aroid Mix do I need for repotting?

A 3-quart bag typically handles 2-3 small plants (4-6 inch pots) or 1 larger plant (8-10 inch pot). For large Monsteras or Philodendrons in 12+ inch pots, you'll want the 8-quart option or multiple bags.

Can I mix this with regular potting soil?

You can, but we don't recommend it for true aroids. The whole point of Aroid Mix is the chunky, airy texture. Mixing it with regular potting soil defeats this purpose by making it denser and potentially causing drainage issues. Use it straight from the bag for best results.

Is Aroid Mix organic?

Yes! Aroid Mix is made with 100% organic ingredients including natural orchid bark, our organic Ancient Soil (made from worm castings), and perlite for drainage. No synthetic chemicals or fertilizers.
