Delphinium Oxysepalum

Delphinium oxysepalum requires consistently moist soil for optimal growth and healthy flower production. During dry periods, make sure the soil remains damp at least 2.5 cm (1 inch) below the surface. However, be careful to avoid waterlogged conditions, as this can lead to root and crown rot.

Delphinium oxysepalum is known for its tall, vibrant flower spikes. To encourage new growth and blooms, prune it in early spring by cutting old stems down to ground level. During the blooming season, remove spent flowers to extend the flowering period. Pruning also helps control plant size, improves air circulation, and prevents disease.
