Plant gladiolus bulbs
Since gladioli are not winter hardy, the bulbs are only placed in the ground when night frosts are no longer to be expected. The optimal planting time is around mid-May to June, in mild regions from the end of April.

When planting, do the following:
- Remove weeds from the soil and loosen it well.
- Work some ripe compost and horn shavings (€ 6.39 at Amazon *) into the soil.
- Dig the planting hole.
- In loamy or clay soils, put some sand into the small pit as drainage.
- Place the onions in the soil with the vegetation point (germination point) facing up.
- Cover the gladiolus bulbs with garden soil.
How deep is it planted?
If gladioli are to bloom very early, you can let the germination point protrude from the earth. However, the onion cannot grow in as well and usually needs additional support to prevent it from tipping over.
The optimal planting depth is twice the bulb diameter. If you do not want to do without early flowering, you can drive the bulbs indoors.
The correct planting distance
So that gladioli come into their own, you should plant them in small groups. Don't place the onions too tightly so that the gladioli have enough space to unfold. A planting distance of 10 to 15 centimeters is ideal. This depends on the height of the gladiolus and is usually noted on the plant packaging.
Tips
When buying gladioli bulbs, make sure that they are large, firm and have not yet sprouted. Since the onions have no soil available, they have to use up part of their nutrient supply, they grow poorly and often no longer bloom.
