Dahlias or georgines are highly valued as colorful summer bloomers in the garden and in pots. Sometimes the pretty flowers just don't want to bloom. What can be the reason and what can you do to ensure that the dahlias develop many colorful flowers?
If the dahlia does not bloom or only blooms sparsely, an unfavorable location can be to blame
Why aren't the dahlias blooming?
Various factors can lead to georgines not developing flowers at all or to flower buds not opening but turning brown and rotting on the bush:
- Unfavorable location
- Soil too wet
- Missing nutrients
- Too big tubers
Wrong location
Dahlias are native to Mexico. There the georgines grow in bright sunlight. Plant georgines in a location that is as sunny as possible. Although they also tolerate partial shade, they do not develop as many flowers there.
On the terrace, the dahlias should also be as sunny as possible. But then they have to be watered more often.
soil too wet
There is one thing that dahlias cannot tolerate at all. This is soil that is too wet for moisture to drain from.
Loosen the soil deeply before planting. It is best to mix loamy soil with sand to make it more permeable.
Water georgines regularly, but be sure to avoid waterlogging.
Too few or wrong nutrients
Only use organic fertilizer to provide the dahlia with nutrients. Artificial fertilizers contain too much nitrogen. It stimulates the plant to form many stems so that there is no longer any energy left for flowers.
Before planting, prepare the soil well by amending it with mature compost and horn shavings (€32.93). Slightly acidic soil with a pH of 6.5 is ideal.
Divide tubers that are too large
Dahlias that have formed too many bulbs will flower less. If the individual tubers are too dense, they withdraw the nutrients from each other. Divide oversized tubers before planting. You can use the divided pieces for propagation.
tips and tricks
As a cut flower, the dahlia will only bloom if you choose flowers that are open for the first day. Buds do not open, older flowers usually simply fall off in the vase.
