About Gladiolus
Gladiolus hybrid is a fast-growing bulb in the Iridaceae family. It reaches around 1.2 m tall and 20 cm wide at maturity, with deciduous foliage. Red, pink, yellow, orange, purple and white flowers appear in summer.
Where to grow Gladiolus
Gladiolus suits warm-temperate, subtropical and Mediterranean climates and grows best in full sun. It is frost tender, so protect it from hard frosts or grow it in a sheltered spot or pot.
Soil & planting
Most soils suit Gladiolus provided drainage is reasonable. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Gladiolus is regular, moderate watering. A feed in spring with a balanced fertiliser keeps growth strong. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Gladiolus after flowering to keep it compact and encourage the next flush of blooms. Overall it is moderate maintenance.
Using Gladiolus in the garden
Gladiolus earns its place for cut flowers for the vase and a feature or specimen planting.
Companion planting & design
For a cohesive, low-care bed, pair Gladiolus with other plants that enjoy the same regular, moderate watering and warm-temperate climate. Group three or five together for impact rather than dotting single plants through the garden.
Good to know
Be aware it can self-seed or spread into bushland in some regions — check it is not a declared weed in your area before planting.
