The ultimate fertilising guide for thriving roses all year round

Roses thrive when given the right mix of nutrients at the right time. A balanced feeding plan ensures strong growth, vibrant blooms, and better resistance to disease. Both organic and mineral fertilisers play a key role in keeping these plants healthy. In spring, roses benefit from nitrogen-rich fertilisers like urea or ammonium nitrate. Gardeners should apply one tablespoon per bush to encourage fast leaf and shoot development. This early boost helps establish a sturdy foundation for the season.

By June, the focus shifts to organic matter. Liquid fertilisers such as poultry manure, used at four litres per bush, provide essential nutrients. Seven to ten days later, a second feeding with compost—half a bucket per bush—further enriches the soil.

Phosphorus aids bud formation and speeds up bush growth, while potassium improves moisture retention and wood maturation. This mineral also strengthens resistance to pests and diseases. In autumn, a mix of liquid organic fertilisers and potassium magnesium is worked into the soil to prepare roses for winter.

Micronutrients, though needed in smaller amounts, remain vital. They enhance overall plant strength and promote more abundant flowering throughout the season. A well-timed fertilising routine keeps roses flourishing year after year. The combination of nitrogen in spring, organic matter in early summer, and potassium in autumn ensures healthy growth and prolific blooms. Proper feeding also reduces vulnerability to common problems like pests and drought.
