Plant gladioli in fertile well drained soil in full sun. Adding grit or sharp sand will aid drainage. When the flower spikes appear, water every couple of weeks with a high potash fertiliser. In warm areas they can be left in the ground over winter. Plant around 10-15 cm deep and allow around 25-50 per square meter. Stagger the planting and you will have a succession of Gladioli flowers for many weeks.
