Gladioli tubers can be planted about 7-10 cm deep in 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. Place the tubers about 10-12 cm apart. While planting, add some good potting soil. Mix heavy (clay) soil with sharp sand before planting. This large-flowered gladiolus likes to grow in a warm sunny spot. This large-flowered gladiolus has a lovely purple-yellow colour and is therefore easy to combine. You can use it to create special combinations in the border with tall perennials and dahlias. Preferably plant gladioli in a different spot every year. Do you use gladioli as cut flowers? If so, pick the stems when the bottom flower opens, preferably early in the morning. Place the stems immediately in a vase of lukewarm water with cut flower food.
