Gladiolus Large Flowering 'Sunglow' (Ships in Spring)

Gladiolus

Gladiolus 'Sunglow' is a large-flowering variety featuring bright golden-yellow blooms. The ruffled petals are closely arranged on tall, sturdy spikes, creating a striking vertical display. Growing up to 5 feet tall, it thrives in full sun with well-drained soil and requires regular watering during the growing season. Hardy in USDA zones 7 to 10, the corms should be lifted and stored in colder climates. This variety is excellent for borders, containers, and cut arrangements.

Growing and Maintenance Tips for Gladiolus Large Flowering 'Sunglow' (Ships in Spring)

Planting: Plant corms in spring after the last frost, 4 to 6 inches deep and 6 inches apart, with the pointed end facing up. For continuous blooms, stagger plantings every 10–14 days until midsummer.
Location: Full sun is best. Choose a sheltered spot to protect tall flower spikes from wind.
Soil: Well-drained, sandy or loamy soil with a slightly acidic to neutral pH (6.0–7.0). Add compost or grit to improve drainage.
Watering: Water deeply after planting, then weekly during active growth. Mulch helps retain moisture and suppress weeds.
Temperature: Hardy in USDA zones 8–10. In colder zones, lift corms in fall and store in a cool, dry place.
Fertilization: Apply a balanced fertilizer (e.g., 5-10-10) at planting, then every 4–6 weeks during the growing season.
Pruning: Remove spent flower spikes to encourage more blooms. Allow foliage to die back naturally to feed the corm.
Staking: Tall varieties benefit from staking to prevent flopping. Insert supports early to avoid damaging roots.
Propagation: Lift and divide corms in fall. Replant healthy corms and save offsets for future seasons.
Pest & Disease: Watch for thrips, aphids, and fungal issues. Rotate planting sites and ensure good air circulation.
