Planting & Care

How to Plant and Care for Helvetia Gladiolus

Planting Your Bulbs

Choose the Right Location – Select a sunny spot with well-draining soil. Gladiolus thrives with at least 6–8 hours of sunlight per day.

Plant at the Right Time – In colder regions, plant bulbs after the last frost when the soil has warmed to at least 50°F (10°C). In warmer zones, you can plant in early spring.

Spacing and Depth – Plant bulbs 4–6 inches deep and space them about 6 inches apart. Planting at different times in intervals of two weeks ensures a longer blooming season.

Watering Needs – Keep the soil consistently moist but not soggy. Water deeply once or twice a week, depending on weather conditions.

Ongoing Care

Mulching – A layer of mulch helps retain moisture and suppress weeds.

Fertilizing – Use a balanced fertilizer (10-10-10) every few weeks for optimal growth and blooming.

Staking Tall Stems – Since Helvetia Gladiolus can grow up to 4 feet tall, staking the stems can prevent them from toppling over, especially in windy areas.

Deadheading and Cutting Blooms – To encourage continuous flowering, remove spent blooms. For cut flowers, snip the stems in the morning when the lower blossoms begin to open.
