Plant Doctor Flowers, Fruits and Roots Liquid Potassium Fertiliser

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.
