Fertilise only for an identified need
Why this can help
Avoiding excess fertiliser reduces unnecessary nutrient inputs and the risk of nutrients leaving the garden in runoff. Soil and plant needs help determine an appropriate application.
One possible next step
Check whether feeding is needed, using soil testing or appropriate local horticultural advice.
What changes the outcome
A deficient plant and an overfertilised lawn are different cases. Follow local guidance and keep products off hard surfaces and away from drains. No fixed emissions or runoff reduction applies to every garden.
The action
One possibility
Adding fertiliser routinely without checking need
Another possibility
Using an appropriate amount when needed
Avoiding excess fertiliser reduces unnecessary nutrient inputs and the risk of nutrients leaving the garden in runoff. Soil and plant needs help determine an appropriate application.
Check whether feeding is needed, using soil testing or appropriate local horticultural advice.
