Power Of Cinder In Gardening Soil Mix

Unleashing The Power Of Cinder In Gardening Soil Mix: A Gardener’s Guide

Gardening and landscaping require finding the perfect balance. One often-overlooked, but incredibly versatile addition to potting soil mixes is cinder, also known as volcanic rock or scoria. This porous and lightweight material comes with a myriad of benefits that can significantly enhance your plants’ health and vitality. In this blog, we’ll explore the various advantages of incorporating cinder into your potting soil mix.

Natural Material

Natural Material:

Cinder stands out as a natural horticultural product derived from volcanic rock or Burnt Industrial coal. This natural origin provides unique properties that cater to various gardening and landscaping needs. Its lightweight and porous nature make it a valuable addition to enhance soil characteristics.

Size And Packaging:

Packaged in a durable bag or container, Cinder consists of small-sized pieces ranging from 2-10 mm in diameter. This thoughtful packaging ensures protection from moisture and damage during storage and transportation while maintaining the product’s integrity.

It can be seamlessly integrated into planting soil or garden soil to enhance drainage, prevent soil compaction, and foster healthy root growth. Additionally, it serves as an effective top dressing for pots, containers, or beds, contributing to moisture retention and weed control.

Improves Soil Drainage And Aeration

Improves Soil Drainage And Aeration:

Washed Cinder’s porous structure plays a pivotal role in enhancing soil drainage and aeration. This property reduces the risk of waterlogging and root rot in plants by allowing excess water to drain freely. The result is well-aerated and well-drained soil, promoting optimal plant health.

Cinder’s porous structure promotes increased aeration within the potting soil. This facilitates better oxygen circulation around the plant roots, preventing root suffocation and encouraging robust root growth. Improved aeration allows air to circulate freely through the soil, providing oxygen for optimal plant development.

Habitat For Indigenous Beneficial Microorganisms

Habitat For Indigenous Beneficial Microorganisms:

Cinder’s porous spaces create an ideal habitat for indigenous beneficial microorganisms. These microorganisms play a crucial role in soil health by breaking down organic matter, cycling nutrients, and promoting overall soil fertility. The incorporation of cinder fosters an environment that supports these microorganisms, contributing to the long-term well-being of your plants.

Neutral PH

Neutral PH:

  • Cinder boasts a neutral pH, making it compatible with a broad spectrum of plants, including acid-loving and alkaline-loving varieties. This pH neutrality ensures that the soil remains conducive to diverse plant species’ specific needs.
  • Cinder’s remarkable attributes include its durability and long-lasting nature. Unlike some soil amendments that break down over time, Washed Cinder remains intact, providing ongoing benefits to the soil without frequent replacement
  • Cinder’s lightweight and easy-to-handle nature make it a gardener’s delight. Its user-friendly characteristics enable effortless mixing with other soil components and seamless application as a top dressing, all without adding excessive weight to pots or containers.
  • Cinder is a natural and sustainable horticultural product. Free from harmful chemicals or synthetic additives, it embodies eco-friendliness, ensuring safety for plants, animals, and the overall environment.
HVO Black Lava Cinder

HVO Black Lava Cinder

Mined from an Ancient Lava Cone, Black Lava Cinder is a locally sourced soil amendment that breaks up garden and orchard soil, promoting breathability. It also serves as a robust filter and drainage medium, fostering a healthy substrate for plant growth.

Utilizing Black Lava Cinder in your soil can significantly enhance plant drainage, moisture retention, aeration, vitality, and importantly it can act as a habitat for beneficial indigenous micro-organisms . As it decomposes, this granulated material releases essential elements like magnesium, calcium, and iron, contributing to the overall health of the soil and supporting the proliferation of beneficial microorganisms. These are in the HVO Top Soil and you can radically increase the amount of these beneficial indigenous microbes by adding in one pound per cubic yard to create an even healthier and productive soil. 


In conclusion, from its natural origins to its versatile applications, cinder proves to be a valuable asset for gardeners and landscapers alike. Whether you’re aiming to enhance soil characteristics, add a decorative touch, or contribute to sustainable practices, Cinder stands as an environmentally friendly, user-friendly, and effective solution for your gardening and landscaping needs.

By harnessing the power of this volcanic rock, you can create an environment that nurtures healthy, thriving plants. This will ensure your gardening success.
