In the worst case, the onions and thus the entire specimen were damaged. Remember: Always plant out from the beginning of May, otherwise the flowering will not take place this year or it will come much later.

2. Not enough sun

Gladioli are true sun worshipers and need a place in direct sun, otherwise they will be lazy to flower. They must also be protected.

3. Set too flat

The irises must be sunk deep enough into the earth to find support. So plant your specimens twice as deep in the ground as the bulb is wide. Otherwise it will not be able to anchor itself and absorb sufficient nutrients, which will delay flowering.

4. Withered flowers

A gladiolus always forms the flowers from bottom to top. Often the lower flowers wither, which stops the growth of the upper buds, as all the energy is put into seed formation. Immediately remove withered flowers to allow adequate energy for top flowers.

5. Nutritional deficiency

Do not forget to provide the planting site with sufficient nutrients. Because the hungry plants need a lot of nutrients in order to develop the beautiful flowers. It is best to spread a load of ripe compost or horn meal to stimulate the vitality of the plant.

tip: Do not be surprised if you are cared for correctly and if the gladiolus species take longer to open their flowers. When the gladiolus blooms does not only depend on the weather and care, it also depends on the game Soil conditions and the quality of the onion matter what makes it impossible to make the final one Predict flowering time.
