Best Fertilizer for African Violets – Fertilizing Tips & Tricks

African Violets are very popular among houseplants because of their velvety-looking leaves and long-lasting blooming season.

They are also easy to propagate and grow. You just have to follow a few straightforward rules to have them happy.

Water techniques and the amount of light needed are only two of these rules, but fertilizing is also very important for African Violets.

It is important how to feed and what to use as a fertilizer. Because not all of the fertilizers are suitable for African Violets.

African Violets need to be fed in order to be healthy, but they need water-soluble fertilizer and the ratio of the nutrients need to be developed especially for the plant’s need.

In this article, I will review five African Violets fertilizers and I will talk about how and when to fertilize these plants.

This fertilizer sends the right balance of nitrogen, phosphorus and potassium to the African Violets’ roots and helps the plant grow healthy and strong. It also stimulates flower production.

How and When to Fertilize African Violets?

Before I am saying anything about the procedure and timing of the fertilizing, I must say that you should always read the labels of your fertilizer.

It is important to avoid over-fertilizing and fertilizers should be used as directed and with the proper dosage as it is advised on the label.

Usually, African Violets’ fertilizers are used every 4 to 6 weeks, but as I presented you above, some of them can be used weekly or whenever you water your plant.

You should fertilize your African Violets from spring to autumn, and leave them to rest during the winter. Even if they bloom, they grow slower, and they don’t need fertilizer.

Are Coffee Grounds Good for African Violets?

Coffee Grounds are highly acidic and adding this to any soil, that also becomes acidic.

As African Violets prefer acidic soil, coffee grounds can be a very good and natural fertilizer for these plants.

However, you should be also careful with the amount of coffee ground you are using. Too much caffeine can lead to stunt growth and increase the risk of fungal disease.

You can add coffee ground from time to time to the soil. Just apply it on the top of the soil and then mix them a little bit.

You can also water your African Violets with water that contains coffee grounds.

Is Epsom Salt Good for African Violets?

Epsom salt is a form of magnesium and sulfur crystal and can be easily dissolved in water.

Magnesium sulfate is often a missing mineral from the potting soils and using Epsom salt for your plants, sometimes is essential.

However, not all plants react well to this mineral. So, what about African Violets?

Yes, Epsom salt is a great fertilizer for African Violets.

Applied once per month, Epsom salt will make your African Violets thrive and explode in blooms.

Dissolve two tablespoons of Epsom salt in one gallon of water (what should be room temperature) and mix it until the salt dissolves completely.

Then water your African Violets as you do it usually.

Allow all this mixture to drain away before placing the saucer back in its place.

Can You Use Aquarium Water for African Violets?

Yes, you can use aquarium water for your African Violet.

Aquarium water accumulates nitrogen, phosphorus, potassium and ammonia, also contains lots of beneficial micro-organisms that help to process these nutrients.

Therefore, aquarium water can be used as fertilizer for your African Violets.

However, not all fish-tank water can be used for these plants. If you have a salt-water aquarium, you should avoid using it for African Violets.

The salt from the salt water could harm your plants.

Also, avoid using the aquarium water if you used chemicals to adjust the water’s pH level or you have been treating the fish for diseases.

Very dirty aquarium water should also be kept away from your African Violets, as this may do more harm than good to your plants.

Wrap Up

To keep your African Violets healthy and help them bloom, you should fertilize them regularly.

It is up to you, which fertilizer to use, but make sure, it is water-soluble and you read the label on how to use it.

If you follow the instructions and the dosage, you can’t go wrong and your plants will be thriving.

Also, to avoid the built-up salts in the pot and the soil, you can flush the container every 3 months.

Pour the water on the top of the soil, but avoid the leaves. So, you should pour the water under the leaves and continue pouring the water, until this comes out of the draining holes.

Then leave it to drain and you can place the saucer back to its place. Also, clean the crusted salt off of the pot.
