Pot up helianthemum plants and grow them on until large enough to plant outdoors. When they are well grown, acclimatise them to outdoor conditions over 7 to 10 days before transplanting into their final positions. Transplant rock roses into moderately fertile, neutral or alkaline soil, in full sun. Helianthemum dislike wet ground, particularly during winter. Improve heavy soil conditions by adding coarse grit or sharp sand prior to planting. Once established, rock roses can easily tolerate dry sandy soils.
Feed and water regularly throughout the growing season while young plants become established. Once established, rock roses are relatively drought tolerant and require minimal maintenance. After flowering, prune helianthemum stems back to within 3cm (1") of the previous year's growth.
