Instead of applying a single large dose of fertiliser, split the application into smaller but more frequent doses. Photo: 123rf.com

Select slow-release or controlled-release fertilisers. They are designed to release nutrients over an extended period, rather than all at once, which significantly reduces the risk of nutrient loss through leaching or runoff during heavy rain.

Choose solid granular fertilisers over liquid forms, as liquids are more susceptible to being washed away by rain.
