How to Fertilize blood flower?
Balanced perennial feed every four weeks from spring through summer

blood flower · Scadoxus multiflorus
Also known as: imperial flower
Plant bulbs in late winter or early spring, with necks at soil level, in loam-based potting compost with added leaf mould and grit. Grow under glass in full light with shade from hot sun. Flowering will be prolonged if light levels are reduced when the buds open. Water freely when in growth and apply a dilute balanced liquid fertiliser monthly. Keep just moist when dormant and do not pot on regularly as flowering is best when congested
