Diatomite for Orchids:

A unique growing medium.

Do you want a medium that is non-hazardous, non-toxic and environmentally safe?

Do you want less watering and spend less time on repotting?

Diatomite is a sedimentary rock primarily composed of the fossilized remains of unicellular fresh water plants known as diatoms. Over the millennia the diatoms have been compressed to create one of the most effective growing mediums available.
Our diatomite is Maidenwell ™ Diatomite and comes from an Australian mine that has a fresh water origin. Maidenwell ™ is free of contaminants and salts that make most other sources unsuitable for horticulture.

Diatomite consists of approximately 90% silicon dioxide, with the remainder of its contents being elemental minerals, which are essential for orchid growth.

WHAT ARE THE BENEFITS OF USING DIATOMITE?

High Silica Content	Silica is essential for healthy plants and roots. Because diatomite is 90% silica, your orchids will receive a slow release of silica resulting in healthier more robust orchids.

Absorbency & Porosity	Diatomite is naturally very porous, and can hold 150% of its weight in water. The silica content, natural absorbency, and porous qualities result in a slow release of water and nutrients to your plants, contributing to higher yields and less watering.

Capillary Action & Lateral Movement	The porosity of the Diatomite contributes to its ability to draw water, while moving water and nutrients laterally throughout the medium, making Diatomite ideal for Hydroponics!

Air Penetration	Diatomite is multifaceted and varies in size. Because each rock is unique in shape it does not compact while in the pot. This leaves pockets, allowing air to penetrate and circulate to the root zone.

Sterilized, Non-Toxic, pH Neutral	When Diatomite is mined it is heat treated to over 600 degrees Celsius, making it completely sterile and safe for all of your planting needs. Whether you are using 100% Diatomite or you are adding it to an orchid mix it will not contribute to changes in pH.

Environmentally Friendly	Diatomite is a fossil, making it natural, safe and an environmentally conscience alternative. Our supplier has visited the mine in Australia, and we are confident that the practices used to mine Diatomite are safe and in accordance with Australian environmental guidelines.

Long Lasting, Natural & Reusable	Diatomite is inert and will not break down or decompose like other growing mediums. It is natural and completely reusable. When dry, Diatomite is extremely lightweight, making it ideal for plant shipping purposes. Because it is reusable and long lasting it is economical and cost effective for long term use.

Small Grade Mix - For your finer rooted orchids and seedlings.

Medium Grade Mix - This is the ‘starting point’ for most orchids in 3 1/2” pots and larger, including Paphiopedilums and Phragmipediums.
