African violets are popular as houseplants primarily because of their flowers. But sometimes the flowers don't bloom. There can be many reasons why an African violet no longer blooms. Here are the most common causes of failure to bloom.
Why isn't my African violet blooming?
An African violet will not bloom if it is in the wrong location, has a lack of water or poor water quality, suffers from a lack of nutrients or is affected by diseases and pests. Pay attention to partially shaded locations, slightly moist soil, regular fertilizer and pest control.
Wrong location
African violets do not like direct sunlight. They much prefer to be in partial shade. If exposed to the harsh midday sun, they will stop blooming. Locations on the north, east or west window are well suited.
Furthermore, these plants don't like cool locations and certainly don't like drafts. When temperatures are around 18°C, hardly any flowers are produced. If the temperatures continue to fall, the flowering will stop completely.
Even if the African violets are on the bright window sill in the warm living room, they may not bloom. The reason is often that the base of the plant is too cool. Because it is so close to the window, the window sill cools down quickly. This can be remedied by insulating materials such as a wooden board under the pot of the African violet.
Water shortage and poor water quality
Another reason could be incorrect watering. African violets need slightly moist soil. It is therefore not a suitable location for them above a running heater, as the soil there dries out quickly. Warm, low-lime to lime-free water is used for watering. Stale or decalcified tap water or rainwater are ideal.
Lack of nutrients
A lack of nutrients can also prevent flowering. African violets should be fertilized every 2 weeks with liquid fertilizer (€8.00 on Amazon). This is particularly important between March and September. In addition, these houseplants should be repotted and placed in a new substrate as soon as the pot is completely rooted.
Diseases and/or pests
Last but not least, diseases and pests can also cause flower failure. Among others, African violets are often attacked by the following diseases and pests and are weakened to the point where they can no longer bloom:
- Spider mites
- Aphids
- Mealybugs
- mealybugs
- small leaves
- Mosaic disease
- Root rot
Tips & Tricks
Do not plant African violets in a pot that is too large. They develop a large root system there. But the flower is losing priority.
