Growing Dutch Explosion

Plant in full sun in fertile, well-drained soil after all frost risk has passed. Pinch the growing tip early to encourage a bushier shape and more flower stems. Stake plants as they approach full height to keep them upright in wind. Feed with a low-nitrogen fertiliser once buds appear, and water consistently through dry spells to sustain heavy bloom production.

Spacing
Space roughly 2–3 ft apart
Staking
