The fertilizers they require must be soluble in a ratio that best suits their needs.

You should use a balanced fertilizer combined with the main nutrients that the plant needs.

This is usually:

  • phosphorous
  • potassium
  • nitrogen
  • and some minerals

Nitrogen is important for the growth of stems and leaves, phosphorous is responsible for healthy roots and flowering, while potassium is useful for the movement and accretion of carbohydrates to the African violet plant.

African violets need a certain percentage of nutrients in the fertilizers.

The recommended ratio of nitrogen, phosphorous, and potassium is 14-12-14.

Several best fertilizers are effective for African violets, and I will list you some of the best in the market.

The slow-release do the work by nourishing the potting soil as soon as they are applied and providing the plants with nutrients for about two months.

On the other hand, quick-release fertilizers are usually in powder and liquid form, and they need to be diluted with water before watering the soil.

They release their nutrients instantly to the plants once administered and thus work best when the plants need a little push to grow optimally.

These fertilizers are used more often through the growing seasons than the slow release.

Here are the main points:

  • For most fertilizers the ideal dosage is usually each four to six weeks during their growing period. However, this might change depending on the product.
  • Spring is the best season to add fertilizers to the plants. This is because this is the period where plants experience leafy growth and production of flowers. Adding fertilizer in early spring will further encourage this growth.
  • Since some fertilizers are water soluble, you should also be aware of how many times you should water your plants. The African violet plants are adapted to periodic rainfall, meaning they don’t need a lot of water to thrive.
  • The best way to tell when to water the plants is to feel the soil at the plant base; if it’s dry, the plant is ready for watering. Don’t overwater the plants since it could result in yellowing of leaves and wilting.
  • Lastly, it is crucial to observe basic safety precautions when dealing with fertilizers. For instance, wear gloves while working. Also, store the fertilizers away from children and pets.

Fertilizers should be kept in a dark, cool and dry area.

Don’t use household to fertilize your plants, instead use designated containers.

How do I know I have over fertilized my plants?

  • Development of dark brown spots at the tip or center of the leaves.
  • The leaves start to form cracks, wilt, or turn brittle.
  • Development of an orange-colored crystallization on the leaf hairs.
  • Formation of crusty white salt around the pot. This means there are excess fertilizer salts.

Final Thoughts

Unlike outdoor plants, indoor plants require a supply of nutrients by the grower to thrive and bloom.

This makes the use of fertilizers crucial for indoor plants such as African violets.

As mentioned above, some commercial fertilizers have a balanced supply of nutrients made specifically for this plants.

While it might be tempting, avoid over-fertilizing your plants. Always read the directions in the fertilizer’s label before using them.
