Basalt by Florifi: The Earth's Original Soil Superfood

Transform your garden into a high performance ecosystem with Basalt by Florifi. Forged in the intense heat of volcanic eruptions millions of years ago, this premium rockdust is a foundational soil amendment designed for the modern regenerative grower.

Basalt by Florifi provides a permanent structural upgrade to your soil. This soil amendment is a slow-release, mineral rich powerhouse that replicates the natural geological cycles that create the world's most fertile lands. The gritty texture of basalt particles provides little safe spaces where beneficial bacteria and fungi can colonize. The trace elements contained in Basalt serve as a catalyst for essential soil enzymes, accelerating the decomposition of organic matter into rich humus.

Benefits of using Basalt

  • Long-Term Mineral Recharge: Unlike quick-fix fertilisers, basalt provides a slow-release "buffet" of essential trace minerals and micronutrients (such as iron, magnesium, and calcium) that are often depleted in overworked garden soils.
  • Permanent Soil Improvement: As a volcanic rock dust, basalt doesn't wash away or evaporate. It physically improves soil structure and increases the Cation Exchange Capacity (CEC), meaning your soil becomes significantly better at holding onto nutrients and delivering them to your plants.
  • Carbon Sequestration: Through a natural process called "enhanced rock weathering," basalt reacts with rainwater and CO2​ to lock carbon into the soil as stable carbonates. Amending your garden with basalt is a small but genuine way to help mitigate climate change.

Simple Application

Whether you are revitalising an established garden or starting from scratch, Basalt is incredibly easy to apply......

For top-dressing, simply sprinkle around the base of your plant, scratch it gently into the top inch of soil, and water thoroughly to activate the microbial breakdown.

For new soil mixes, thoroughly blend Basalt into soil or potting media before planting.

Safe for Your Whole Backyard

Give your plants the best without worrying about your four-legged friends. Our Basalt Rock Dust is completely non-toxic to pets and won't harm the bees, butterflies, or ladybugs that visit your garden. It’s a pure, volcanic mineral that enriches the soil while keeping your sanctuary safe for everyone.

How to Use Florifi Basalt

Earth-Born Energy: From Potted Plants to Garden Borders

Basalt Volcanic Rock Dust is a geological reset for your garden. Whether you’re tending a balcony sanctuary or expansive landscape borders, this ancient volcanic amendment provides a permanent mineral foundation. Its dense trace element profile and high silica content create the ultimate environment for rugged, resilient, and vibrant growth.

Method 1: Top-Dress Application

The "Mineral Infusion" for established plants.

  • Dosage: Apply 10ml per litre of soil volume. For larger pots use 400ml per 40 litres.
  • Frequency: Reapply once a season. Unlike organic matter, Basalt minerals persist in the soil, providing a sustained, long-term release.
  • Activation: Lightly scratch into the surface and water in to settle the volcanic dust into the soil structure and engage the "weathering" process.

Method 2: Compost & Bokashi Integration

The Biological Catalyst for nutrient-dense humus.

  • Wormaries:
    Mix a small handful of Basalt with your feed onto surface of your
    wormery, reapply once a month for a mineral rich vermicompost.
  • Scatter 400ml of Basalt per square metre of raw organic matter. Layering the dust within the heap accelerates the breakdown of carbon and creates mineralised humus or sprinkle between layers in your Bokashi bin.
  • The Synergy: The organic acids produced during Bokashi fermentation or aerobic composting help "digest" the rock dust. This breaks down the volcanic minerals into a bio-available form much faster than nature could alone.
  • The Result: You aren't just making compost; you’re creating a Mineral-Rich Super-Humus that re-mineralises your soil while providing a massive boost to microbial housing.

Method 3: New Soil Mixes & Potting Blends

The "Geological Battery" for new outdoor beds, borders, and containers.

When preparing a new growing area, Basalt acts as a permanent structural and nutritional anchor. It upgrades the Cation Exchange Capacity (CEC) of your soil, allowing it to hold onto nutrients more effectively.

  • For Potting Mixes: Thoroughly blend 1 cup per 50 litres of potting media. This ensures that every inch of the root zone is fortified with silica and essential trace minerals.
  • For Outdoor Beds & Borders: Broadcast 0.5kg per 10 square metres. Incorporate it into the top 10–15cm of soil to ensure the minerals are locked in where root development is most active.
  • Why it works: Integrating Basalt directly into the mix provides Soluble Silica from day one. This strengthens plant cell walls, leading to thicker stems and a natural "armor" against pests, disease, and environmental stress.

The Volcanic Edge: Basalt doesn't just feed the plant; it rebuilds the soil. By returning primordial minerals to the earth, you are creating a self-sustaining ecosystem that is more resilient to drought and more productive over time.

Safety Precautions

  • Always wear gloves when handling dry amendments to avoid skin irritation.
  • Avoid inhaling dust, wear a dust mask or respirator when measuring or applying.
  • Wash hands thoroughly after use.
  • Keep out of reach of children and pets.
  • Do not ingest. If swallowed, seek medical advice immediately.
  • Avoid contact with eyes. If contact occurs, rinse thoroughly with clean water.
  • Store in original packaging in a cool, dry place away from direct sunlight and moisture.
  • Do not mix with incompatible chemicals, check product labels before combining amendments.

Storage Instructions

  • Store in a cool, dry place away from direct sunlight and heat sources.
  • Keep in original, sealed packaging to prevent moisture absorption.
  • Avoid storing near water sources or in damp environments such as unventilated sheds.
  • Do not store alongside liquid fertilisers or incompatible chemicals.
  • Ensure the seal is tightly closed after each use.
  • Keep out of reach of children and pets at all times.
  • Shelf life of 12 months from purchase, is best maintained when stored correctly.

Frequently Asked Questions

Find answers to common questions about Basalt

Basalt is a slow-release mineral amendment. While some of its soluble silica and trace minerals become available within weeks, the full "weathering" process happens over months and years. However, if you mix it with Bokashi or active compost, the organic acids produced by those microbes help "digest" the rock, unlocking the minerals for your plants much faster.

Basalt is a pH-neutral volcanic rock. It has a very low salt index, meaning it won’t burn delicate roots or salt-sensitive seedlings even if applied liberally. It is a gentle, steady way to build soil fertility without the risk of over-fertilising.

Basalt is often preferred by organic growers because it typically contains a higher concentration of Magnesium, Iron, and Calcium, and is particularly prized for its high Silica content. It also weathers (breaks down) more consistently than harder granites, making its nutritional elements more accessible to your soil biology.
