The attractive flowers of the gladiolus add colorful accents to the garden and are also popular cut flowers for the vase. Since the attractive flowering plants are quite sensitive to frost, it is important to plant the bulbs in the ground at the right time.
When is the best time to plant gladioli?
The best time to plant gladioli is in spring, preferably in June, when there is no longer any threat of ground frost. However, wild forms such as the Siegwurz varieties can be planted in autumn. To extend the blooming period, plant a few bulbs every week into June.
Autumn or spring, when to plant?
Gladiolus are sun worshipers and like it extremely warm. They are therefore usually planted in spring when there is no longer any threat of frost. In regions where there is still a risk of cold phases in April and May, you should therefore only plant the onions in June.
Extend flowering period
Unfortunately, the gladioli's blooms are over after about two weeks. However, with a simple trick, the flowering period can be significantly extended, so that you can enjoy the beauty of the gladiolus flowers for many weeks.
First of all, there are different types of gladioli that also bloom at different times. Choose early, mid and late flowering varieties that will then open buds one after the other.
In addition, plant a few gladiolus bulbs every week from spring to June. Depending on when it was planted, the flowers will develop and you can expect new shoots for many weeks.
Wild forms of gladiolus
The wild forms of gladiolus include, for example, the Siegwurz varieties. These are much more robust than cultivated gladioli. You can therefore plant the bulbs of these somewhat delicate and smaller wild gladioli in autumn without any worries.
Tip
In harsh areas, you can also grow the bulbs indoors so that the gladioli bloom at the desired time. Place the bulbs thick side down on potting soil (€10.00 on Amazon) and water regularly. Soon the gladioli will sprout.
