Plant Doctor Flowers, Fruits and Roots is a fast-acting liquid fertiliser that is high in potassium and buffered with humic acid. It is made for the budding, flowering and fruiting stages and for root development, on plants such as citrus, tomatoes, roses and native flowers.

Why you'll love it

  • High in potassium. Potassium supports flowering and fruit production, so this is the feed to reach for when a fruit tree blooms well but sets little fruit, or when flowers drop early.
  • Fast acting. As a liquid it delivers nutrition straight away, which suits a mid-season feed for potted plants and a lift after pruning.
  • Roots and trunk as well as blooms. It is used to build trunk and root strength, and to help seeds germinate and seedlings establish.
  • For fruit quality. Growers use it on crops with low sugar levels, measured as Brix, or with uneven flowering.

How to use it

Shake well and apply to soil or foliage in the cooler part of the day.

  • Ornamentals: 10 to 20ml in 8L of water over 10 sqm, every 4 weeks
  • Vegetables: 10 to 20ml in 8L of water over 10 sqm, fortnightly
  • Trees, fruit, nuts and grapevines: 100 to 170ml per 100 sqm, every 6 to 8 weeks
  • Lawns: 80 to 120ml per 100 sqm, every 4 weeks

Use a weaker mix, with care, on phosphorus-sensitive natives such as grevilleas and banksias.

What's in it

  • Nitrogen 9%, phosphorus 7%, potassium 19%
  • Trace elements: iron, manganese, copper, zinc, boron, magnesium and molybdenum
  • Humic acid and natural wetting agents

Sizes

  • 1L. The smallest bottle, for a few pots, a rose bed or a backyard citrus tree.
  • 4L. The middle size, for a productive garden with fruit trees and vegetable beds.
  • 10L. The bulk container, for orchards, large plantings and growers.

Specifications

  • Type: liquid fertiliser, high in potassium, buffered with humic acid
