A netlon bag of 60 mixed coloured Gladiolus bulbs. Gladiolus are very floriferous and bring height and colour to any garden and are wonderful cut flowers. You can plant the Gladiolus tubers about 7-10 cm deep in the spring. First loosen the soil well and sprinkle a layer of sharp sand at the bottom of the planting hole. This allows rainwater to drain well under the tubers. Space the tubers about 10-12 cm apart. Add some good potting soil when planting. Mix heavy (clay) soil with sharp sand before planting. This large-flowered Gladiolus likes to grow in a warm sunny spot. Preferably plant Gladiolus in a different spot every year.
