Harvest Tips
Impatiens kilimanjari is grown for ornamental flowers rather than harvest. Deadhead spent blooms regularly to encourage continuous flowering. For seed collection, allow a few flowers to fade naturally; seed pods will develop and eventually burst, scattering seeds. Collect ripe pods just before they split to prevent seed loss.
