Description

Super concentrated plant-derived non-petrochemical surfactant / wetter & soil conditioner

Nature’s Soil Wetter is a super-concentrated, eco-friendly soil wetter and conditioner that restores dry, compacted, or lifeless soil. Designed to fix hydrophobic soils and improve water and fertiliser efficiency, this plant-based formula is safe for lawns, garden beds, vegetables, natives, pots, and even golf greens or turf farms. Backed by Australian CSIRO research and made from 100% natural complex organic compounds, Nature’s Soil Wetter unlocks your soil’s true potential, helping it absorb, hold, and use water like a sponge.

Use Nature's Soil Wetter when your soil has become water repellent, irrigation or rainfall is struggling to penetrate the root zone, or plants are showing signs of moisture stress despite regular watering. It's ideal for improving water infiltration, reducing runoff, and helping soils retain moisture more effectively in lawns, gardens, orchards, and agricultural systems. Nature's Soil Wetter can also be used alongside most fertilisers and crop inputs to maximise water efficiency as part of a broader soil management program.

Nutrient Profile: 

  • Derived From: Complex organic compounds, plant-based surfactants, natural humates & fulvates
  • Trace Elements: Naturally occurring (70+ trace minerals in low concentrations)
  • Formulation Type: Soil wetting agent & conditioner (non-fertiliser)

Why choose Nature's Soil Wetter:

  • Fixes hydrophobic (water-repellent) soil fast
  • Improves water retention in sandy soils
  • Breaks through compaction in clay soils
  • Boosts fertiliser efficiency (especially nitrogen)
  • Removes toxic residues and binds harmful salts
  • Safe for all plants, including natives and edibles
  • Concentrated, fast-acting and biodegradable 

Nature's Soil Wetter is 100% Natural, Non-Toxic & Petrochemical-Free. It is derived from: Complex Organic Compounds (COCs), Botanical Extracts (e.g. Taraxacum officinale), Non-toxic surfactants & corn starch derivatives, Natural humates and fulvates. Lastly, it contains 70+ trace elements and minerals essential for soil. Whether you’re battling dry patches on your lawn, poor drainage in the veggie patch, or lifeless potting mix, Nature’s Soil Wetter helps water reach where it matters most—your plants’ roots. It’s the perfect foundation for a drought-resilient, water-wise garden.

How it Works

The Science Behind Nature's Soil Wetter:

Nature’s Soil Wetter tackles one of the most overlooked soil challenges, hydrophobicity, or water repellence. Common in sandy soils, compacted clays, and degraded soils, this issue causes water to bead and run off rather than soaking in where plants need it. By reducing water’s surface tension, Nature’s Soil Wetter improves infiltration and rehydration, delivering moisture directly to root zones while enhancing soil structure over time. Unlike synthetic wetting agents, its natural colloidal chemistry and plant-based surfactants support soil biology. The formula binds and retains moisture, reduces nutrient leaching, and stabilises nitrogen fertilisers for up to 80 days. It also detoxifies soils by binding harmful residues and heavy metals, while buffering pH for a more stable growing environment. Whether on turf, in gardens, or across farms, Nature’s Soil Wetter does more than move water, it regenerates soil function, boosts nutrient efficiency, and builds long-term resilience in any growing system.

In summary, nature's soil wetter has the following functions: 

  • Water Penetration: Breaks water’s surface tension to move deeper into the soil
  • Soil Structure Repair: Softens compacted soil and helps form beneficial soil crumbs
  • Fertiliser Stabilisation: Enhances nitrogen retention—extends urea effectiveness up to 80 days
  • Root Zone Hydration: Keeps moisture near plant roots longer, reducing stress
  • Soil Detox: Binds and neutralises salts, toxins, and heavy metals
  • pH Buffering: Helps soil resist extreme swings in pH

FAQ

What is Nature’s Soil Wetter and how does it work?

Nature’s Soil Wetter is a natural, plant-based soil wetting agent and conditioner designed to fix hydrophobic (water-repellent) soils. It reduces water’s surface tension, allowing moisture to penetrate deeper into the soil profile. This improves root hydration, boosts fertiliser efficiency, and helps repair compacted or sandy soils.

Is Nature’s Soil Wetter safe for all plants?

Yes. It is 100% natural, non-toxic, petrochemical-free, and safe for all plant types—including lawns, vegetables, fruit trees, natives, potted plants, and even turf farms or golf greens.

What’s the best way to apply Nature’s Soil Wetter?

Nature’s Soil Wetter works best when it penetrates into the soil. If applying with a pressure sprayer, you should water it in afterwards. Otherwise, apply with a hose-on bottle for even distribution.

How often should I apply this product?

For general soil improvement, apply once every month. If you’re trying to correct poor soil structure or severe hydrophobicity, more frequent applications may be beneficial.

How much of this product should I apply?

The standard application rate is 100ml for every 100m². If treating less often (such as once a season), apply 300ml per 100m².

How soon after spraying Nature’s Soil Wetter can I mow?

It’s best to wait 8–12 hours after application before mowing. The longer you leave it, the more effective the treatment will be.

Should I mow my lawn before or after application?

For best results, mow your lawn before applying Nature’s Soil Wetter. This allows the product to penetrate the soil more effectively without being trapped in the leaf layer.

Can it help with lawn dry patches and water run-off?

Absolutely. Nature’s Soil Wetter is highly effective on lawns suffering from dry patches, uneven wetting, or water run-off. It helps spread water evenly across the soil surface and ensures moisture penetrates down into the root zone.

Is it environmentally friendly?

Yes. Being derived from complex organic compounds, botanical extracts, and natural surfactants, it is fully biodegradable and safe for waterways, pets, and beneficial soil microbes.

Excellent Soil Wetter

I’ve been using Plant Doctor’s Nature’s Soil Wetter on my lawn and garden, and it has made a huge difference. My soil was struggling to absorb water, but after applying this, I noticed better penetration and less runoff. The added humic and fulvic acids are a great bonus for soil health. It’s easy to apply, works well in clay-heavy soil, and lasts for weeks. Highly recommend for anyone dealing with dry or compacted soil!

Lawn was struggle with the heat and I noticed some brown patches through my buffalo Applied some of this soil wetter after grooming lawn and you can definantly notice a difference

I live in a hot and dry area, this product helps me keep the soil wetter and my water bills down. Win Win. Easy to apply and mixes well with other products.

Nature's Soil Wetter

Another great product from the team at Plant Doctor. Was drawn to this company as they have a strong background in horticulture/agriculture products where it is important to provide effective and efficient use of products. Backed by science, their products are easy to use with lower application rates avoiding unnecessary overuse of products.

Nature’s Soil Wetter

I have used this product in combination with 5 other Plant Doctor products for the past four years and my Sir Walter lawns are pretty spectacular. The service and delivery are both prompt and efficient.

Excited to use this product!

After initially buying the Lawn Lover's Pro bundle earlier this year, I decided to purchase the Nature's Soil Wetter as well. I love how I can just simply mix this in with the other products in the bundle (excluding Liquid Iron), saving me time and effort!

Great company and great service

I bought this soil wetter as a complementary addition to the Lawn Lover's Pro bundle. (See my review there!) The application rate is just as easy, and it can be mixed with all the other products for application, so it makes total sense to add this wetter to the same spray. With the results I've gotten from the Pro bundle, I'm confident that the soil wetter will perform as described!

LUSH AND GREEN

Love this product, made my new lawn from light green to a bright vibrant green in only two applications! Highly recommend. Purchased as part of the Lawn Lovers Pro Pack.

This is perfect for lawns and garden beds

This product really does help

Excellent quality product and extremely good value. Shopped around for a good quality wetting agent and you cannot go past Plant Doctor.

That Soil Wetter Stuff

Get ya hands on this Soil Wetter Stuff, your lawn is going to need it when things heat up this Summer! After only one application, you can notice the difference, the water really soaks down into the soil!

Great product

Works very well, like the fact that you can put multiple products together for one application

top notch

best value for money. I run this through my EZFLO at a low rate all year long. Stress free environment.

Perfect for dry soil

Improved the water retention and reduced the water run off from the soil in my new house... Old soil needed a refresh water just ran off the top until I started using this regularly and broke through the hydrophobic layer on top. Soil still needs top dressing and a bit of a refresh but that needs to wait until the coming seasons reno but man did this help get through the last season.

Great Product!

As good as a soil wetter as I have used, applied on well and can be mixed with other products.

Great soil wetter

For the price this is unreal, great soil wetter allows for water to penetrate deep into the soil. Also use it as a surfactant when spraying fungicide and it definetly helps

Top product, well priced.

This is a great product at a very competitive price. Highly recommend to anyone looking to benefit their lawn.

Finally solved my water repelling problem!

I have very sand soil which loves to repel water and anything else I throw at it. I finally got around to getting Nature's Soil Wetter after finding it here at Plant Doctors. Wow!!! What a difference withing a week. My grass is finally taking up everything I throw at it. Getting it into the root zone where it should be. Thanks again Plant Doctor!

Incredible product!

With only 2 applications this has improved my soils uptake of moisture so much! Love it!

Great soil wetter for new lawn

I have used all the pd products except this one so decided to buy a small bottle to test on the new turf. Wow it works wonder to let all the water soak in very well and lawn established much quicker.

Amazing Green Zoysia

I bought the Plant Doctor Natures Soil Wetter on eBay to complement the Stimulizer, Liquid Iron, Quantum, Seaweed Secrets and Activ8Mate products that I was already using - as a combination they bring a depth of healthy colour to my lawn that I have not seen with any other combination of products that I've tried

Nature's Soil Wetter

Great product!

Parts of my clay soil just couldn't hold water before, was hard as rock, I gave it the suggested amount of soil wetter and the soil now holds water and stays moist. Will be buying more!

Fantastic Product

I applied it for my lawn in addition with Lawn Lovers (Ben Sims) Bundle Pack. My lawn is keeping green and strong. It is a great product and good value for money.

Works wonders for lawn and the garden

I use this for both the lawn and the garden and works amazingly well. Had very hydrophobic soil around a young citrus tree - added some NSW into a watering can and hey presto! No more water run off! This is also used as part of my lawn care regime to ensure adequate water penetration. Overall very impressed.

Great wetter for a great price

Have been using this soil wetter for a while now (2/3week apps) has held up amazing helped the lawn get through 40+ degree days and great for spot spraying.

Hydrophobic Lawn

I was challenged to try out this product & how glad am I that I gave this a go! I have quite a decent incline in my front yard and I struggle to retain water there! Since using this soil wetter it has really helped my lawn retain water and keep the soil moist! I will be using this product for a long time to come!
