Manutec Bloom Booster Soluble 500g – High-Potassium Flowering Plant Fertiliser

High-Potassium Soluble Fertiliser for Bigger, Brighter Blooms

Manutec Bloom Booster Soluble is a specialised, water-soluble fertiliser made to power the flowering stage of your plants. With an N-P-K of 12.5 / 2.5 / 28.0, it is high in potassium, the nutrient that drives strong flowering, and it is formulated for increased flower size and colour on all flowering plants. This is the 500g pack.

Formulated for the Flowering Stage

Flowering is when plants need a different nutrient balance, leaning heavily on potassium rather than nitrogen. This blend is built around that need, supporting more and bigger blooms with better colour, while still supplying the nitrogen and phosphorus plants use for healthy stems and roots. The result is a stronger, longer-lasting flower display.

Fast Uptake, Flexible Application

Because it is fully water-soluble, it dissolves completely and is taken up quickly, so plants get nutrients when they need them most. You can apply it as a root drench or as a foliar spray, whichever suits your setup, giving you direct, efficient feeding through the critical flowering period.

Use Almost Anywhere

Bloom Booster suits both indoor and outdoor plants and works across garden beds, pots, hanging baskets and hydroponic systems. It is a versatile choice for flowering plants of all kinds, from roses and potted colour to fruit-bearing plants that you want to flower and set well.
