The Dos and Don’ts

Begonia Rex, also known as the painted-leaf begonia, is a popular houseplant that is loved for its strikingly beautiful foliage. The plant is native to tropical regions and requires specific care for optimum growth and health. One of the essential aspects of taking care of your Begonia Rex plant is fertilization. Proper fertilization can enhance the plant’s growth and help it thrive. However, incorrect fertilization or using the wrong type of fertilizer can harm your Begonia Rex plant. In this article, we will discuss the dos and don’ts of fertilizing your Begonia Rex plant.

Dos of Fertilizing Your Begonia Rex Plant

Use the Right Type of Fertilizer

Begonia Rex plants require a balanced, water-soluble fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. It is best to use a fertilizer that has a ratio of 20-20-20 or 10-10-10. These fertilizers provide the necessary nutrients for your Begonia Rex plant to grow healthy and strong.

Follow the Recommended Fertilizer Schedule

Begonia Rex plants require regular fertilization during their growing season, which is from spring to early fall. It is best to follow the recommended fertilizer schedule, which is usually every two weeks during the growing season. However, it would help if you reduced the frequency of fertilization during the winter months when the plant is dormant.

Dilute Fertilizer Before Application

It would be best if you diluted the fertilizer before applying it to your Begonia Rex plant. Diluting the fertilizer will prevent root burn and ensure that your plant receives an adequate amount of nutrients without causing harm.

Apply Fertilizer After Watering

It is best to apply fertilizer after watering your Begonia Rex plant. Applying fertilizer to dry soil can cause damage to the roots and hinder growth.

Don’ts of Fertilizing Your Begonia Rex Plant

Over-Fertilize Your Plant

Over-fertilizing your Begonia Rex plant can cause more harm than good. Too much fertilizer can lead to root burn, stunted growth, and even death in severe cases. Follow the recommended fertilizer schedule and avoid over-fertilization.

Use Fertilizer with High Nitrogen Content

Using fertilizers with high nitrogen content can cause your Begonia Rex plant to produce excessive foliage at the expense of flowers. The ideal ratio of nitrogen, phosphorus, and potassium for your Begonia Rex plant should be balanced.

Fertilize Newly Transplanted Plants Immediately

It would be best if you did not fertilize newly transplanted Begonia Rex plants immediately after transplanting them. The roots are still recovering from transplant shock and may not be able to absorb nutrients correctly. Wait for at least two weeks before applying any fertilizer.

Use Cold Water to Dilute Fertilizer

It would be best if you did not use cold water to dilute fertilizer. Coldwater can shock the roots and cause damage to your Begonia Rex plant. Use room temperature water or slightly warm water when diluting fertilizer.
