African violets are popular as houseplants mainly because of their flowers. But sometimes there is no flowering. There can be many reasons why an African violet does not bloom (anymore). Here are the most common reasons for a failure to flower.

Direct sunlight can be the reason why the African violet does not bloom

Wrong location

African violets do not like direct sunlight. They prefer to stand in partial shade. If exposed to the relentless midday sun, they will stop blooming. Locations on the north, east or west window are well suited.

Furthermore, these plants do not like cool locations and drafts. When temperatures are around 18°C, there are hardly any buds being produced. If the temperatures continue to fall, the flowering stops completely.

Even if the African violets are standing on the bright window sill in the warm living room, they may not bloom. Often the reason is that the foot of the plant is too cool. Due to the proximity 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 African violets.

Water shortage and poor water quality

Another reason can be incorrect casting. African violets need slightly moist soil. It is therefore not a suitable location for them over a running heating system, as the soil there dries out quickly. Warm and 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 with liquid fertilizer every 2 weeks. This is particularly important in the period between March and September. In addition, these houseplants should be repotted and placed in a new substrate as soon as the pot is fully rooted.

diseases and/or pests

Last but not least, diseases and pests can also cause a loss of flowers. Among others, African violets are often afflicted by the following diseases and pests and are so weakened that they can no longer flower:

  • spider mites
  • aphids
  • Mealybug
  • mealybugs
  • leaflets
  • mosaic disease
  • root rot

tips and tricks

Do not plant African violets in a pot that is too large. They develop a large root system in it. But the flower loses priority.
