How to Fertilize African Violets
Feeding Your African Violet
What fertilizer should I use for my African Violets?
What do those three numbers mean on the front of the fertilizer label?
These numbers, also known as N-P-K, represent Nitrogen (N), Phosphate (P), and Potash (K).A simpler way of looking at it is to think of the numbers as a percent. A “20-20-20” fertilizer is the rough equivalent of saying that the fertilizer is 20% Nitrogen, 20% Phosphate, and 20% Potash.
What are the benefits of Nitrogen, Phosphate, and Potash to my African Violet?
Nitrogen: The key function of Nitrogen is to help your African Violet grow.
Phosphate: Aids in maintaining a strong, healthy root system. Phosphate also plays an important role in producing blooms.
Potash: There are many important functions of Potash, two of which are allowing for easier water uptake and helping to synthesis plant carbohydrates for feeding purposes. Potash also plays a role in helping your African Violet fight off potential diseases.
How do I know if my African Violet is deficient in Nitrogen, Phosphate, or Potash?
Nitrogen Deficiency: If the leaves of your African Violet are smaller than you are used to and/or the leaves of your African Violet are turning a pale/yellowish color along their edges, there is a good chance your African Violet is not getting its required amount of nitrogen.
Phosphate Deficiency: If your plant is not producing blooms despite the fact that it gets plenty of indirect sunlight, there is a good chance your African Violet is not getting its required dose of Phosphate. Be sure to check that your African Violet isn’t overpotted as well. Overpotting is when we pot a plant in too large of a container, causing it to grow in sub-optimal conditions. A phosphate deficiency can lead to your African Violet not blooming as expected, or even at all.
Potash Deficiency: Whitening/Yellowing of leaves, brown leaf tips, and smaller blooms than normal can all be attributed to a potash (potassium) deficiency.
Feeding your African Violet is a simple, surefire way to instantly become a more successful grower. Take the time to try it out, your plant will reward you a thousand times over with more vibrant, healthy growth.
