These lightweight granules are celebrated for their exceptional moisture retention, porosity, and long-term durability in soil, making them ideal for growers seeking a dependable, low-maintenance medium.
Used widely across bonsai, succulent, cactus, and no-till gardening communities, diatomite's unique structure promotes optimal root oxygenation and thermal regulation. It also slowly releases bioavailable silica, contributing to stronger plant structures and improved resistance to stress.

Excellent moisture retention with high porosity
Lightweight and easy to mix into custom soil blends
Rich in bioavailable silica to strengthen plant cell walls
Does not compact or degrade quickly in soil
Helps buffer temperatures in containers for even root zone conditions
Ideal for bonsai, cactus, succulents, and no-till gardening systems
Diatomite is a smart choice for growers looking for a cost-effective, high-performance soil additive that enhances both moisture regulation and soil aeration. Its slow breakdown rate makes it perfect for long-term use, and its lightweight nature also reduces shipping costs—especially valuable for bulk buyers. With the added benefit of bioavailable silica, your plants gain structural resilience, improved nutrient uptake, and a stable growing medium that supports healthy development in even the most sensitive species.
What types of plants benefit most from diatomite?
Diatomite is ideal for cacti, succulents, bonsai, and any container-based or no-till garden setups needing enhanced drainage and aeration.
How does it compare to zeolite or pumice?
While all three offer drainage benefits, diatomite is the lightest and most cost-effective to ship. It also adds silica, which pumice and zeolite do not.
Can I use diatomite on its own?
Yes, but it’s most effective when used as a part of a well-balanced soil blend for optimal root structure and hydration.
Is it safe to handle?
Yes, but it’s best to wear gloves and a mask when handling dry diatomite to avoid inhaling fine particles.
Does it release nutrients into the soil?
It releases silica, which is essential for plant strength and stress resistance, though it doesn’t contribute major nutrients like nitrogen or potassium.
