Collection of Double Geraniums

Perennial geraniums are planted during spring or autumn. Not very demanding in terms of position or soil quality, it thrives in the sun, which promotes flowering, or in partial shade. To plant, work the soil to a depth of 20 cm (8in), loosening it well and adding a base amendment such as dried blood or powdered horn at the bottom of the planting hole. Position your plant, removed from its pot, and cover the top of the root ball with 3 cm (1in) of soil. Fill in the hole and water generously to eliminate air pockets. Space the plants 40 cm (16in) apart. If planted during dry weather, it is necessary to water regularly for a few weeks to facilitate root establishment. However, give little water in winter. From July to September, remove faded flowers and leaves to encourage new growth. After flowering, you can also cut back the plant and water well to encourage a neat clump to form.
