Helianthemum abelardoi prefers well-drained soil and requires moderate watering. Allow the soil to dry out slightly between waterings, especially during the warmer months.

Reduce watering significantly in winter to prevent root rot. Overwatering is a common mistake that can lead to plant decline.

Prune Helianthemum abelardoi lightly after flowering to maintain a compact shape and encourage bushier growth. Remove any dead or straggly stems at any time of the year.

Avoid hard pruning into old wood, as it may not recover well. Regular deadheading also promotes more blooms.

Propagation is best achieved through semi-hardwood cuttings taken in mid to late summer. Dip the cut ends in rooting hormone and plant them in a well-draining potting mix.

Keep them moist and in a warm, humid environment until roots develop, which usually takes several weeks.

Repot young plants annually or every two years in spring before new growth begins. Mature plants can be left in their pots for longer periods.

Ensure the new pot has adequate drainage holes and use a free-draining compost mix, such as a sandy loam or a mix with added grit.
