How to Grow
Plant gladioli in groups at 14-day intervals to extend their flowering season, and enjoy their fabulous blooms all summer long. Height: 60cm (24"). Spread: 15cm (6").
More Info
In autumn, allow the foliage to die back naturally before lifting the corms and cleaning them of soil and any remaining stems. Dry them in a well ventilated position for 2 weeks before storing them in a frost-free location for the winter. When growing gladioli in mild areas with particularly well drained soil, it may not be necessary to lift the corms. Apply a dry mulch of bark chips or leaf mould in autumn to protect the corms from cold, wet weather.
