Review of Nature's Soil Wetter Liquid Concentrate, Wetting Agent for Water Repellent Garden Soil - 1

Fantastic Product! Seeing is believing…

My lawn was showing signs of being rather hydrophobic last season so over winter I started applying the Natures Soil Wetter regularly, this allowed the winter rains to get it into the soil profile. The result are have been amazing and a complete turn around, I will be definitely using this product ongoing after seeing the positive results!

Review of Seaweed Secrets Liquid Kelp Tonic, Humic & Fulvic Acid Lawn & Garden Biostimulant - 1L

Seaweed Secrets..

Very impressed with this product so much so that I bought a 5 litre bottle. The results are just amazing after using it to water my seedlings regularly. They are very healthy and have fattened up. I would call this stuff liquid gold.. well done plant doctor, I look forward to purchasing more of your products..

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.

Review of MSM Capsules – High-Purity Organic Sulphur 460mg

MSM Supplement 460mg

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 Quantum H® Liquid Humic Acid Lawn & Garden Soil Conditioner - 1L

Brilliant

I have been using Quantum H on my Santa Anna lawn now for years in conjunction with other PD products and the results have been consistently brilliant. I have found that maintaining soil health is critical component in lawn care, and Quantum H is definitely a part of a “system” to use to achieve results.

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!
