Product Description

A Healthier Garden, From Roots to Harvest

Want more flowers, tastier fruit, or better root development? This powerful yet gentle liquid fertiliser is specially crafted to support plants during their most important stages — budding, flowering, and fruiting. It's fast-acting, full of natural minerals, and easy to apply.

Whether you're growing citrus, tomatoes, roses or native flowers, this is your go-to blend for healthier growth, stronger roots, and vibrant results.

Why choose Flowers, Fruits and Roots Liquid Fertiliser?

  • High in Potassium (K) to support flowering and fruit production
  • Boosts trunk and root strength for better plant stability
  • Helps germinate seeds and establish seedlings faster
  • Supports natural disease resistance with added bio-protection
  • Works instantly — perfect for mid-season pick-me-ups
  • Naturally improves soil structure and media wettability
  • Increases plant sugars (Brix levels) for sweeter fruit
  • Buffered with humic acid for better nutrient uptake
  • Gentle, natural, and environmentally friendly

This liquid fertiliser is perfect for gardeners and growers looking to boost flowering and fruit production or improve root health during key growth stages. Use it when you notice your plants need more flowers or better fruit set, especially if your fruit trees are blooming but not producing fruit as expected. It’s also ideal if flowers are dropping prematurely or if you want to encourage rapid regrowth after pruning. For potted plants, this fertiliser offers a vital mid-season nutrient boost to maintain healthy development. Additionally, it supports crops struggling with low sugar content (low Brix levels) or uneven flowering, helping to enhance plant health and yield quality.

 

Where to use Flowers, Fruits and Roots Liquid Fertiliser?

Lawns (Buffalo, Couch, Kikuyu & More)

  • Not designed for turf — but ideal around citrus trees, berries, or flowering garden beds.
  • Use as a foliar spray or soil drench during flowering or fruiting.

Gardens (Veggies, Flowers, Trees, Pots)

  • Apply to roses, hibiscus, vegetables, tomatoes, cucumbers, stone fruit trees, and flowering natives.
  • Ideal for feeding potted fruit trees or container flowers.
  • Use fortnightly during active growth for best results.

Farms & Larger Properties

  • Perfect for high-value crops like citrus, grapes, tomatoes, capsicum, stone fruits and nut trees.
  • Can be used through boom sprays or fertigation systems.
  • Especially effective in sandy or nutrient-depleted soils needing fast-acting potassium.

Whether you’re growing in garden beds, containers, or orchards, this formula provides targeted nutrition when plants need it most.

The Science Behind Flowers, Fruits and Roots Liquid Fertiliser

Flowers, Fruits & Roots Liquid Fertiliser is carefully formulated with a high concentration of potassium (19%), nitrogen (9%), and phosphorus (7%), alongside a balanced suite of essential trace elements such as iron, manganese, zinc, copper, boron, magnesium, and molybdenum. Potassium plays a crucial role in regulating water movement within plant cells, enhancing flowering, fruit development, and sugar transport, which leads to sweeter, healthier produce. Nitrogen supports vigorous leaf and shoot growth, while phosphorus is vital for robust root establishment and successful seed and flower formation. This blend is further enriched with humic compounds that act as natural chelators and soil conditioners, improving nutrient availability, soil structure, and root interactions. The inclusion of natural wetting agents ensures better water absorption and retention, promoting even moisture distribution in the growing media. Together, these elements create a synergistic effect that reduces nutrient lockout, stimulates beneficial microbial activity, and enhances overall plant vigour during critical growth phases.

Great Products

By: Gavin on 15 March 2024
I really like all my Plant Dr products and i'm sure this one will be great too

Great product

By: Ashley on 12 May 2023
Amazing results from using this product on my fruit trees. Also seeing a bit increase in flowering on my camellias .. only been using it for 1 season but results speak for themselves.

Love this

By: Mary on 21 April 2023
Love this high Potassium food for my all my plants and helps them flower. This will be a regular from now on.

Flowers, Fruits and Roots

By: Michelle on 30 March 2023
I started using this product 6 months ago for establishing new turf sod. Fantastic results with root production on the treated vs non-treated area and with low nitrogen there wasnt the excessive leaf growth so more energy went into establishment and didn’t need mowing too soon. Great product for some of the new hybrid Couch grasses and Zoysia that need low nitrogen. 120mls per 100m2 monthly delivers a great amount of certain trace elements as to the majority of soil nutrient analysis that I work with. Great product to incorporate into your lawn nutritional program and especially through the cooler months of the year also.

Awesome NPK combo!

By: Shoua on 2 January 2023
I got this as a trial for my vegetable patch, and boy it worked like magic due to its well-balanced nutrient content, especially the NPK. This all-in-one fertilizer is so economical as you can avoid the application of other individual fertilizer which can be quite costly. I use this fertilizer every fortnight and supplement it with Plant Doctors Seaweed solution (low dosage) every week. Highly recommended the product and will definitely be back for a repeat order. Cheers!

game changer!

Have been using this for the past month and plants/flowers have never looked better

Wow! What a difference!

By: Adrian on 24 March 2020
I used this regularly with other Plant Doctor products, and wow what a different this stuff makes! Flowering trees just explode with flowers, I had a pineapple head throw a pineapple out nearly straight away and I applied it to newly transplanted tubestocks of lilly pilly's and they established overnight. An amazing product and part of my fertilising and soil conditioning regime and I'd highly recommend it for healthy plants and lawn!

Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
