Pruning stiff twinspur — FAQ
When should I prune stiff twinspur?
After each flowering spike finishes, through spring and summer. Cut spent flower spikes down to the basal leaf rosette using clean scissors. Avoid cutting into the crown. After trimming, apply a light balanced liquid feed and ensure consistent moisture to prompt the next flush.
How often does stiff twinspur need pruning?
After each flowering spike; typically two to three times per season. Stiff twinspur (Diascia rigescens) produces long, upright flowering spikes and benefits from trimming after each flush to promote fresh blooms. Cut spent flower spikes back to the basal rosette of leaves once flowering ends. This keeps the plant compact and encourages multiple repeat flushes rather than a single long but diminishing season.
