Growing & Maintenance Tips for Allium 'Globemaster'

To care for Allium Globemaster, ensure it is planted in well-drained soil with full sun exposure. Water the plant regularly during the growing season, but allow the soil to dry out between waterings to prevent root rot. After flowering, let the foliage die back naturally to nourish the bulb for next year's growth.
