Engineered to hold moisture, build stronger roots and keep your lawn growing green during hot and dry periods.
Grass CAN actually grow well on sand - but only if you manage it properly, which means you have to give it help...
Help getting moisture into the profile, and keeping it there
Help giving the roots something to drink
Help preventing random hot spots and the 'daily water, still looks dry' cycle
That's exactly why my Wetting Agent Combo exists!
What's In The Wetting Agent Combo?
It's a simple two-product system that fixes the two major issues sandy soils have: Getting water into your soil profile, and helping roots make use of that moisture.
Once you solve these two things, sand becomes stable, predictable, and capable of growing unbelievable grass.
Let’s break it down:
Step One: Retain Pro - Helps Water Soak In, Spread Evenly, and Stay Where Your Roots Are
Retain Pro is a professional-grade wetting agent built specifically for the kind of soil that’s most common in Australia. It will…
● Break the surface tension of water so it soaks in instantly
● Help moisture move sideways through the soil for consistency
● Reduce leaching so water doesn’t disappear straight past the roots
● Recondition dry, crusty, water-repellent soils
● Keep your lawn hydrated throughout summer
What this means: You get more out of every drop of water. Your watering actually works. And your lawn stops frying the moment you miss a day.
Step Two: WSF Seaweed SMX - Feeds, Strengthens and Deepens Your Root System
Once the soil is actually holding moisture properly, it’s time to look after the plant sitting in it.
WSF Seaweed SMX brings seaweed, potassium, and trace goodies that:
● Ignites new root growth into that now-moist profile
● Improves stress tolerance (heat, wind, drought, wear)
● Increases density and colour
● Supports recovery from dry patch, scalping, or inconsistent maintenance
● Strengthens the plant without loading it up with nitrogen
Retain Pro looks after the soil. Seaweed SMX looks after the plant.
That’s why they work so well together on sandy ground.
The Results You Can Expect:
Once this combo is in your program, sandy soil stops feeling like a problem you’re always fighting… and starts feeling like something you’ve finally got under control.

How to Use This Combo on Sandy Soil:
● Retain Pro: 200ml per 100m²
● WSF Seaweed SMX: 200ml per 100m²
● Water it straight into the root zone.
Then: Water deeply every second day in summer (aim for 4–5mm). If it rains, skip the watering.
Apply the same combo again - this sets your foundation.
● Retain Pro: 100ml per 100m²
● WSF Seaweed SMX: 200ml per 100m² Repeat every month during the warm season.
Stay on top of this routine and sandy soil stops being a constant battle… and becomes “just how your block is” — managed, predictable, and capable of growing unreal grass.
