In Zone ME18, England, the ideal time to plant gladiolus is in late May or early June. This window provides optimal growing conditions for the flowers to thrive in the region, so I would not plant, yet.
It's crucial to plant the bulbs at a depth of 4-6 inches (10-15 cm) and space them 4-6 inches (10-15 cm) apart to ensure proper growth and flowering. Gladiolus prefer well-drained soil and full sun exposure. Be sure to water the plants regularly and apply a balanced fertilizer to support healthy growth. By planting during this time, you can enjoy a vibrant and beautiful display of gladiolus throughout the summer months.
