Struggling with acidic soil, poor growth, or nutrient lock-up? Our Dolomite Granules are designed to gently rebalance your soil while delivering essential nutrients that support stronger roots, improved growth, and healthier plants.

Use Dolomite Granules when soil is too acidic (low pH), prior to planting or lawn establishment, and/or as part of a soil improvement program. Typically applied in autumn or early spring for best results.

How it Works

The Science Behind Dolomite:

Dolomite is a naturally occurring mineral composed of calcium magnesium carbonate, making it highly effective for correcting soil imbalances.

  • Raises soil pH by neutralising acidity, creating a more optimal environment for plant growth
  • Calcium supports cell wall strength, root development, and overall plant structure
  • Magnesium is a key component of chlorophyll, driving photosynthesis and green leaf production
  • Improved pH increases the availability of essential nutrients like nitrogen, phosphorus, and potassium

By correcting soil acidity and replenishing key minerals, dolomite helps unlock the full potential of your soil. 

 

Application

Before applying dolomite, it’s essential to test the soil pH and magnesium levels. Over-application can lead to nutrient imbalances.

Using dolomite effectively can give you a thicker, greener lawn and healthier soil over time.

Application Rate:  Typically, apply about 5 kilograms per 100 square meters, but this may vary based on your soil's needs.
Timing: Apply dolomite in the autumn or early spring for the best results. It takes a few months to fully break down and affect soil pH.

Safety

Safety Guidelines

Test your soil before application to determine if pH correction is needed, as over-application can lead to nutrient imbalances. Apply evenly and water in well after use. Store in a cool, dry place and keep sealed when not in use.

Review of Liquid Fulvic Acid Lawn & Garden Biostimulant, Premium Soil Nutrient Chelator - 1L

Seed Germination

I have tried the fulvic acid on seed germination with fantastic results. Soaked Adenium seeds overnight in diluted fulvic acid.. the results were amazing, once the seeds were planted they germinated a lot quicker than normal with nearly 100 % germination. Very happy with this product and can totally recommend to others.

This MSM Supplement has made a significant difference to my recovery from a serious Lis Franc foot injury after months of little to no improvement. Less pain and more elasticity in the badly injured area of the foot. Could not be happier.

Review of PREMIUM Fossil Shell Flour®: Food Grade DE Diatomaceous Earth - Organic - 800g

Organic Diatomaceous Earth Powder (Food Grade Foss

I’m really impressed with Plant Doctor's PREMIUM Fossil Shell Flour. The powder is finely milled, so smooth it mixes easily into water, smoothies or morning coffee without any grittiness. It’s simple to use, and appreciate that it has no taste or smell. The 800g bag is great value and will last a long time when using a teaspoon daily. Have observed improvements in my digestion and energy levels, and general skin feel too. Delivery was super quick, and the packaging is resealable and well-labeled. The quality is outstanding, and I know exactly where I’ll be getting my next supply, definitely sticking with Plant Doctor. Many thanks to the team!
