The Twinspur plant benefits from a balanced fertilizer application every four to six weeks during the growing season. It is advisable to apply a slow-release fertilizer at the beginning of the growing season to provide the plant with consistent nutrients throughout the season. Over-fertilization should be avoided, as it can lead to weak growth and less flowering.
Pruning
Pruning is essential to maintain healthy growth and encourage blooming in Diascia elongata Benth. The plant should be pruned at the end of winter or early spring, before the blooming season. The pruning should involve removing any dry or damaged stems and cutting back the plant's overall size. Deadheading should also be done regularly throughout the blooming season to promote more flowering.
Propagation
