Fertilizing Your Begonia Plant:
The Dos and Don’ts

Updated: April 19, 2023

Begonias are popular houseplants that are known for their beautiful flowers and foliage. To keep your begonia healthy and happy, it is important to fertilize it properly. In this article, we will discuss the dos and don’ts of fertilizing your begonia plant.

Dos of Fertilizing Your Begonia Plant

Use the Right Type of Fertilizer

There are many types of fertilizers available in the market, but not all of them are suitable for begonias. When looking for a fertilizer for your begonia, look for one that is high in phosphorus and potassium, as these nutrients are essential for flowering and root development.

Follow the Instructions on the Label

Different fertilizers have different application rates and schedules. Always read and follow the instructions on the label to avoid over-fertilizing or under-fertilizing your begonia plant. Over-fertilizing can burn the roots and leaves, while under-fertilizing can result in poor growth and fewer blooms.

Fertilize During the Growing Season

Begonias grow actively during the spring and summer months. This is the best time to fertilize your plant, as it needs nutrients to support its growth and flowering. During the fall and winter months, reduce or stop fertilizing your begonia as it enters a period of dormancy.

Don’ts of Fertilizing Your Begonia Plant

Don’t Over-Fertilize

Over-fertilizing your begonia can be harmful to its health. Too much fertilizer can cause salt buildup in the soil, which can burn the roots and leaves. Symptoms of over-fertilization include yellowing leaves, stunted growth, and wilting.

Don’t Use Fertilizer on Dry Soil

Fertilizer is most effective when applied to moist soil. Water your begonia plant thoroughly before applying fertilizer to ensure that the nutrients are absorbed properly. Applying fertilizer to dry soil can lead to nutrient burn and waste.

Don’t Apply Fertilizer Directly to Leaves or Flowers

Fertilizer should be applied to the soil around the base of your begonia plant, not directly on its leaves or flowers. Applying fertilizer directly to leaves or flowers can cause burning and damage.

FAQs

Q: How often should I fertilize my begonia?

A: Begonias should be fertilized every two weeks during the growing season (spring and summer) with a balanced fertilizer. Reduce or stop fertilizing during the fall and winter months when your plant is dormant.

Q: Can I use compost as a fertilizer for my begonia?

A: Yes, you can use compost as a natural fertilizer for your begonia. Compost provides organic matter and nutrients that help improve soil structure and fertility.

Q: What should I do if my begonia is over-fertilized?

A: If you suspect that your begonia has been over-fertilized, flush the soil with plenty of water to remove excess salts. Allow the soil to dry out before reapplying fertilizer at a lower rate.

Q: Can I use liquid fertilizer for my begonia?

A: Yes, liquid fertilizer is a good option for begonias as it is easily absorbed by the roots. Follow the instructions on the label for application rates and schedules.

In conclusion, fertilizing your begonia plant is an important part of its care routine. By following these dos and don’ts, you can ensure that your plant receives the right nutrients in the right amount at the right time. With proper fertilization, your begonia will thrive and reward you with beautiful blooms and foliage.
