Results timeline

What to expect over the season.

Medigrow keeps working the longer you feed.

Day 7

Greener, firmer growth

Colour deepens and new leaves firm up as the roots start feeding.

Day 14

New growth takes off

Fresh leaves and shoots push out as the plant builds structure.

Day 30

Stronger roots and canopy

Denser foliage and a deeper root system, right through the plant.

Day 60+

A fuller, healthier plant

Peak-season payoff — lush growth, richer colour and natural pest resistance over time.

Why it works

Built for strong growth.

Stronger roots, lusher foliage

Nitrogen-led and aimed at the growth phase, so plants build deep roots, dense foliage and sturdy structure — not just height.

Results you can see fast

Absorbed through leaf and root, so greener colour and fresh growth often show within a week or two — not a season of waiting.

One bottle, a whole season

Concentrated at just 2 mL per litre — one bottle feeds for months, at a low cost per feed, with no refills mid-season.

Safe where you live

Mineral-based, so you can feed confidently around kids, pets and pollinators.

The maths gardeners love

One bottle. A whole season.

Medigrow founders Mark and Jake at a market stall

Australian · family-run · since 2000

Medigrow didn't start as a home-garden product.

Mark grew up in and around family market gardens, nurseries and the wholesale produce markets — then spent the better part of 25 years in commercial growing, feeding crops most home gardeners never get to see.

Jake watched everyday gardeners pay premium prices for watered-down, filler-packed bottles that never came close to what the professionals were using. It never sat right with either of them.

So they did the obvious thing — took the real, farm-grade feed and brought it straight to home gardens. No middleman. No fillers. No watering it down. Still Australian owned, still family run, still made the way Mark first learned it.

Questions, answered.

What is Medigrow and what is it for?+

Medigrow is a concentrated liquid fertiliser for the growth phase. It's nitrogen-led — the N in NPK — the nutrient that drives strong roots, lush foliage and healthy vegetative growth on lawns, leafy veggies, young plants and trees.

When should I use Medigrow instead of Medibud?+

Use Medigrow (nitrogen-led) during the growth phase for roots, leaf and lawns. Switch to Medibud (phosphorus & potassium) the moment plants start budding, flowering or setting fruit.

How often should I fertilise, and when, in Australia?+

Feed every 1–2 weeks through the active growing season — spring through autumn is the main window, and spring is the most important feed. In warm, subtropical regions like Queensland you can feed almost year-round; ease off while plants are dormant in winter.

Is Medigrow safe around kids and pets?+

Medigrow is made from natural minerals and is safe around children and pets when used as directed (2 mL per litre of water); just let foliage dry after feeding.

How is this different from Seasol or the hardware-store bottle?+

Seasol is mainly a seaweed tonic — excellent for stress and roots, but very low in NPK, so it isn't a complete feed. Medigrow is a complete, farm-grade mineral plant food concentrate with the nitrogen and trace elements growing plants actually need — no fillers.

Can I use it on Australian natives?+

Good news: many natives (grevilleas, banksias and other Proteaceae) are sensitive to phosphorus. Medigrow is nitrogen-led and naturally low in phosphorus, so it's a safe choice for phosphorus-sensitive natives — just feed at the standard rate.

Liquid fertiliser vs granular — which is better?+

Liquid is absorbed fast through both leaf and root (foliar feeding), gives even coverage and lets you make mid-season corrections — results are often visible within a week or two. Granular releases slowly over months. Many gardeners use liquid for quick, even results.

How much do I use, and how long does a bottle last?+

Just 2 mL per litre of water. A 5 L bottle of concentrate makes 2,500 L of liquid feed — around 278 watering cans, or a full season for most home gardens, at roughly 36c per feed.

What if I don't see a difference?+

You're covered by our 30-Day Greener Guarantee. Feed for 30 days — if you don't see a greener, healthier difference, reply to your order email and we'll refund you. Real results build over a season, but foliar feeding is often visible within a week or two.

When will my order arrive?+

We dispatch every weekday and ship Australia-wide. Most metro orders arrive in 2–5 business days. Free shipping over $149.
