What makes APSU Soil different?

APSU Soil is the world’s first company to recreate real biomes as living soil systems. Each blend begins with samples taken from natural ecosystems around the globe — rainforests, deserts, bogs, and forest floors — then rebuilt through laboratory analysis and field testing. We combine modern soil science with the balance of nature to engineer soils that behave like the real thing. No gimmicks, no guesswork, just living systems you can trust.

Do your soils contain synthetic fertilizers or chemicals?

No. APSU Soil products are 100% organic and biologically active. We use natural nutrient sources such as compost, kelp, and mineral rock dusts to create long-lasting fertility through microbial life, not synthetic salts or chemical feeds.

Are your soils ready to use right out of the bag?

Yes. Every APSU blend is fully balanced, aged, and biologically mature before packaging. There’s no “cooking” or prep time required — just open, moisten, and plant. From delicate carnivorous plants to heavy-feeding crops, our soils are ready when you are.

What are your main soil types?

• LivingSoil™ – A versatile, balanced blend for everyday growing — ideal for houseplants, herbs, flowers, and vegetables.

• SuperSoil™ – A complete, water-only system for high-demand plants and heavy feeders.

• ForestFloor™ – Recreates tropical rainforest and woodland conditions for aroids, ferns, mushrooms, and moisture-loving ornamentals.

• Cactus Jacked™ – A fast-draining, mineral-rich desert mix for cacti, succulents, and arid species.

• KillerSoil™ – A specialized bog ecosystem mix for carnivorous plants like Nepenthes, sundews, and Venus flytraps.

• Terrarium Soils – We can’t forget our Reptile friends, Naturalistic biome substrates for terrariums and vivariums — designed for humidity control, drainage, and bioactivity.

Can I reuse APSU Soil?

Yes. Our soils are designed to regenerate, not expire. By adding SuperCharge™ or ReNew™, you can recharge nutrients and microbial activity for the next cycle. Over time, your soil becomes even more alive, just like natural earth systems.

What does “biome-inspired” mean?

Each APSU Soil product is modeled after the exact environmental conditions of real habitats. We collect soil samples from around the world, study their composition through laboratory analysis, and replicate them using organic, sustainable ingredients. It’s a precise blend of science and nature — a process no other company offers at this scale.

Can I use APSU Soil indoors?

Absolutely. LivingSoil™, ForestFloor™, and SuperSoil™ are ideal for houseplants, indoor gardens, and greenhouses. They’re clean, odor-free, and biologically stable — perfect for creating thriving indoor ecosystems.

Can I mix APSU Soil with my existing soil?

Yes. Our blends make excellent conditioners and microbial boosters. Mixing even small amounts into garden beds or potting mixes improves structure, nutrient availability, and biological health.

Do you offer bulk or wholesale options?

Yes. APSU Soil partners with retailers, nurseries, and hydro stores across the U.S. and beyond. For wholesale or distribution inquiries, contact call (202) 391-1020.

Where are your soils made?

All APSU Soil products are blended and finished in the United States using locally sourced materials. We take inspiration from soils around the world but make them accessible to everyone, everywhere.

Why the name APSU?

In ancient mythology, APSU represented the primal freshwater beneath the earth — the source of all life. It’s a fitting symbol for our mission: to bring soil back to life through knowledge, science, and respect for the natural world. Its also short for Appellation Supply, our original name.

What’s your philosophy?

Healthy soil equals healthy life. APSU Soil exists to reconnect growers with the living foundation beneath their plants. We let nature lead, science guide, and results speak.
