The bulbs of some gladiolus species can be left in the ground in winter
Which gladioli are allowed to hibernate outside?
Gladioli are sun worshipers and unfortunately not very hardy. Leave the bulbs in the ground in the autumn and usually do not sprout the plants next year, because the small tubers freeze. However, not everyone has the opportunity to overwinter the gladiolus bulbs in a cool, frost-free place or in the basement. Here it is advisable to place hardy gladioli, which are less sensitive to frost and can stay in the bed even in the cold season.
Frost-resistant gladioli
These varieties are usually a little bloodsucker than the known breeding gladioli. But this makes the special charm of the winter-resistant varieties, which make very good in natural gardens. They bloom a little earlier than the gladioli set in the spring. If you plant both hardy and cultivated gladioli, you can extend the flowering period without having to put Gladiolus bulbs into the soil with a time delay.
Winter protection necessary
Even frost-resistant gladioli that hibernate outdoors require sufficient protection against cold. Since the cover will last for weeks or even months on earth, it is important that the protective coat allows enough air to pass through. Lack of oxygen inevitably leads to rot, which can extend to the root.

Tips
In harsh areas, it is advisable to pick up the frost-resistant varieties from the ground and to hibernate them in a suitable location like normal breeding gladioli. The room should be as cool as possible so that the gladioli do not expire prematurely.
