Incorporate plenty of organic matter when planting and water well in dry weather, especially newly established plants. Apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant to help seal in moisture, feed the soil, and reduce the need for weeding.

Deadhead spent flowers regularly to encourage continuous blooming. If the plant becomes too leggy or untidy later in the season, trim lightly to encourage fresh growth and more flowers.

During the first growing season, regular watering is crucial to establish deep roots. Once established, Geraniums show improved drought tolerance. A feeding of balanced, slow-release fertiliser in spring will support blooming.

At the end of the growing season, cut it back to ground level in late autumn or early spring. Every 3-4 years, consider dividing the plant in spring to maintain its vigour.
