XXL pack of 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. If you plan on using this flower in a cutting, pick the stems when the lower flower opens, preferably early in the morning and immediately place the stems in a vase with lukewarm water with cut flower food.
