How it Works

 

The Science Behind Neem Seed Oil:

Neem oil contains naturally occurring bioactive compounds, primarily Azadirachtin and Nimbin, which contribute to its effectiveness in plant systems.

  • Azadirachtin influences insect behaviour and lifecycle processes
  • Nimbin supports plant surface protection and microbial balance
  • Natural sulphur content contributes to plant health and resilience
  • Rich in fatty acids and antioxidants that help coat and protect plant surfaces

This makes neem oil a versatile tool in integrated plant care, working without harsh synthetic chemicals.

Great product

I have been struggling to get rid of powdery mildew on my pumpkin and this product has been amazing to control and prevent the spread

Awesome for getting in rid of pests

It works beautifully treating common pests without affecting the environment.

Good neem oil

I have been using neem oil in the garden for a long time and as I get products from Plant Doctor I order Neem from here too. Good quality product no issues at all. Remember to keep in a warmer place in winter as it gets just about solid on colder days. Keeps the garden nice and healthy. As always great service and fast shipping, stoked with the order.

Phenomenal!

I live in a tropical area and near a chicken farm which has wreaked havoc with all of my animals since we moved here. My horses have gotten horrific rain scald, even the dogs have had itching skin conditions when they have contact with the soil under the house. All the animals have looked like they have mange and have been scratching non stop. I've tried *EVERYTHING* under the sun, every expensive oil, soap and remedy, scoured horse forums looking for every remedy. The amount I've spent on rugs that gets destroyed due to the itching constantly washing and disinfecting everything and the amount of time trying to get this issue under control. After years I came across someone talking about Neem oil so it felt like a last ditch chance. I diluted the Neem oil in a 1:7 ratio with coconut oil, (a little stronger for the first dose) and sprayed it on all the animals and it seemed the itching seemed to stop almost instantly, you could tell the animals seemed more relaxed than I've seen in years, and my jaw hit the floor with how quickly I saw hair growth beginning to return. We also get bot flies and other biting insects and I've watched them drop dead the moment they try and bite the horses. I haven't rugged the horses in weeks now and with a regular spray of oil they're fine. The horses actually come running when I have the spray bottle in my hand now, I apply it every other day and they get a nice scratch all over while it's applied but it's amazing to see for the first time since we moved here they are glossy, no chunks of hair missing and they're not uncontrollably rubbing on every surface along with the dogs. I hope anyone who is struggling to find a fix comes across Neem oil. I'll never use anything else ever again, I'm so grateful I found this product.

Neem Seed Oil

Used as a soil drench to kill off curl grubs, seemed to work as there was clear reduction of the grubs in my garden beds

Excellent Product

This is the second time we've bought this for our garden, last summer it was a godsend for the defeating the pests, as we don't like using chemicals.

Helpful!!

My cabbages were attacked by aphids but it only took a few days after the application to see the results! No more aphids

Good value for money

Very happy with the product. It has worked out pretty good for aphids

Great Alternative Insecticide

My circumstances compel me to use low toxicity insecticides in my garden and neem oil has certainly hit the mark. To make it even better, the Plant Doctor has been one of the most efficient suppliers that I have ever dealt with. Great service!

Neem seed oil works as advertised !

Great product, applied in the afternoon and noticed a difference by the next morning! will be buying this more often!

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.

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!
