How to grow gladioli: 11 useful tips

Growing gladioli adds to our green corner some beautiful long stems studded with flowers that follow each other one after the other.

These are summer bulbous plants, i.e. flowers that develop from a tuber bulb called the corm. They are beautiful both collected in bunches and placed in the flowerbeds of the garden.


1) For these flowers, almost any type of soil can be fine, but prefer the one that has good drainage and does not stagnant water, with a pH around 6-7 (slightly acid), which you will have fertilized with an organic fertilizer, such as manure or mature compost, before planting, during the hoeing.

2) When planning your garden or balcony, place it in a bright, sunny area with a moderate climate.

3) Plant them in spring, after the frost, with the tip upwards, at a depth of about 4 cm. In the garden, between bulbs, keep about 15-20 centimeters of space.

4) You can also plant gladioli in pots.

5) If you like to have the flower garden continuously, every 7-10 days or so, plant new bulbs.

6) To cultivate gladiolus, provide them with the water they need, especially if it does not rain or rain very little, but do not form stagnant water.

7) To control humidity, you can also mulch the soil.

8) If you want to harvest individual gladioli, you can proceed when the first flower or two flowers bloom, in the evening or early in the morning, cutting them sideways: before composing your bunch, try to leave them in the water in the dark in a cool place. But beware: if you want to plant them again, leave the leaves on the plant as they will be the nourishment of the planted bulb.

9) In any case, remove the dried flowers.

10) Especially if you live in a very cold area, when the leaves turn yellow, pull the corm from the ground leaving 2-3 centimeters of the stem. Then, dry the small corms that have formed by removing the old corm and store them in a bag, in a dry place: you can put them back in place in spring. You can treat the bulbs with a specific product to avoid any fungus.

11) Among the problems, gladioli could be affected by fungi, if the bulb-tuberous is subject to moisture, or by aphids.
