Strengthening plant structure from the roots up

By building and advancing the cellular structure the plant will have a stronger foundation to maximise photosynthesis, naturally increasing growth and health of the plant.

Formulated to create enhanced root systems that increase the plants ability to absorb nutrients from the soil. Better roots means better nutrient uptake.

Dilute with water as per application rates and water at base of the plant, irrigation feed or foliar spray. When used as a foliar spray simply follow the dilution rates and spray until run off. For optimal absorption apply early morning or late afternoon.

Lawn Application Instructions:

Add 150–200ml of Medigrow per 500ml spray tank.

Fill the remainder of the tank with water.

Attach to a garden hose and apply evenly across the lawn surface.

Apply early morning or late afternoon for best absorption.

For faster green-up, apply 3 times in the first week, spaced 2 days apart.

If further applications are required, apply twice weekly until the desired outcome is achieved.

Maintain usual watering schedule and apply monthly thereafter.

Cuttings and seedlings: 0.5ml/L of water.

Juvenile plants: 1 to 1.5ml/L of water.

Established plants: 2.5ml/L of water.

Foliar Spray (DIY): 2ml/L of water.

Foliar Spray (agricultural): 3 to 5L/Hectare

Hydroponic Systems: As per above dilution rates, add to reservoir on completion of premixed nutrient solution. For optimum nutrient update, keep PH between 5.5 to 6.3.

Medigrow is formulated for use from nursery to maturity of all plants and lawns.

Medibud didn’t start as a product for home gardens.

Mark’s passion for growing healthy plants began early, growing up around family market gardens, nurseries, and the wholesale produce market. This experience led him into the commercial growing space, where he worked with liquid plant nutrition focused on plant health, growth, and yield.

Growing up around the family business, Jake was familiar with the products and how they were used. Later, while working in one of Australia’s most well-known hardware retailers, he noticed a clear difference between what commercial growers relied on and what was being offered to everyday gardeners, often more diluted formulas with added fillers and an inflated cost per use.

This revealed an opportunity to make Medibud and Medigrow available to everyday gardeners.

This is where Medibud is today.

Made for gardeners who care about healthy plants.

Fiddle Leaf Fig Recovery
Started using Medigrow on my fiddle leaf when it was struggling and within a few weeks it pushed out 3 new leaf shoots. Leaves look healthier and the plant finally looks happy again.

Healthy growth you can actually see
I’ve been using the Medigrow Liquid Plant Fertiliser for a while now and it’s honestly made a noticeable difference. My plants look greener, healthier and are growing stronger since I started using it.
It’s easy to dilute and apply, doesn’t have a strong smell and works well for both indoor and outdoor plants. If you want a simple fertiliser that actually delivers results, this one’s worth it.

New lawn established really quickly
We recently laid new turf and started feeding it with Medigrow straight away. The grass settled in really quickly and the colour came through nicely after the first couple of weeks.
