Important Mixing Information
Plant Fuel Part A & Part B
Plant Fuel is a two-part fertiliser system.
Part A and Part B should never be mixed together in their concentrated form.
Always:
Add Part A to your watering container.
Add Part B separately.
Mix into the full volume of water being used.
This ensures maximum nutrient availability and stability while preventing nutrient lock-up.
Optimiser Fuel Usage
Optimiser Fuel is designed to be used as a standalone application and is not typically mixed with Root Fuel or Plant Fuel.
The seaweed extracts naturally contain plant hormones that help plants:
Recover from stress
Improve resilience
Support healthy growth
Increase overall vitality
For Healthy Plants
Apply once per month as part of your regular feeding programme.
For Stressed Plants
If a plant has been repotted, is struggling, or showing signs of environmental stress, Optimiser Fuel can be applied with every watering for up to 8 weeks.
Once the plant has recovered, return to the standard monthly application schedule.
