Wayside Gardens Gladiolus Koi Blend Bulbs

To extend your flowering season, plant your bulbs in two-week intervals starting in early spring. This staggered planting schedule ensures that new spikes emerge as the earlier ones finish, keeping your garden colorful for a longer period.

Yes, these are well-suited for containers as long as the pot is at least 12 inches deep to accommodate the 4-foot height and root system. Ensure your container has adequate drainage holes to prevent the bulbs from sitting in water.

Because these gladiolus can reach up to 4 feet in height, they may require staking, especially if planted in an area exposed to strong winds. A simple garden stake or support ring installed early in the season will help keep the heavy, orchid-like flower spikes from leaning or snapping.

These bulbs are hardy in zones 7 through 10. If you live in a colder climate, you should dig up the bulbs in the fall after the first frost, store them in a cool, dry place, and replant them in the spring.

Gladiolus thrive in well-drained, loamy soil. If your garden soil is heavy clay, mix in organic matter like compost to improve drainage and prevent the bulbs from rotting.

Each order contains 15 bulbs, which is enough to create a substantial, colorful cluster in a garden bed or several smaller arrangements in containers.
