 Fertilizer for Begonias

Fertilizing Begonias at different Stages of Growth

Begonias are heavy feeders, they require essential nutrients throughout their life. The soil does not always contain essential nutrients, this shortcoming is then filled by fertilizers. Be it to treat deficiency, maintain growth, or multiply blooms, fertilizers are a one-stop-shop for the plant’s needs.

When Begonias are unfed, they look dull and seem to wilt, this is a clear symptom that the plant needs nutrients or it is because of the abrupt watering schedule.

So, coming back to our main concern which fertilizer to use for begonias and when.

How to fertilizer Begonia

When Begonias are Planted

Begonias are recommended to be fertilized with a balanced NPK fertilizer. Select a balanced fertilizer 10-10-10 or 20-20-20 for Begonia in granular form. Mix it with the soil as per the instructions on the package. Water the soil after application.

When Begonias sprout

When Begonias begin to sprout or reach 3 inches high, take a balanced liquid fertilizer, mix 1 part fertilizer with 3 parts water. Apply the diluted mixture at the base and keep applying every two or three weeks during the growing season.

Fertilizing Begonias in winter

Since Begonias do not grow in winter, it is advisable not to fertilize them in winter. Reduce the fertilizer dosage to one time a month in late autumn. In winter, Begonias do not grow or take up nutrients efficiently below 58 degrees Fahrenheit. Therefore, they must be fertilized in the growing and spring season.

Ideal Fertilizer for Begonias

What to look for when buying fertilizer for Begonias? Begonias need fertilization to grow and bloom. The market is flooded with endless options which makes one confused as to which one is going to work.

NPK

An NPK fertilizer is an ideal choice not just for Begonias but for all plants as well. NPK stands for the proportion of Nitrogen, Phosphorus, and Potassium. The NPK percentage is usually given on the label. For instance, a 10-5-8 NPK formulation means that 10% Nitrogen, 5% Phosphorus, and 8% Potassium is present in the mix.

Nitrogen (N) is responsible for the vibrant color and growth, Phosphorus (P) is credited for root growth, flower bloom, and fruit development, Potassium (K) helps with the overall health and wellness of the plants.

For Begonia, a balanced NPK fertilizer does the trick. A balanced NPK fertilizer means that the NPK is in the same proportion. NPK granular fertilizer is used at the time of potting or planting.

Additional Nutrients

If the fertilizer contains three additional nutrients in addition to NPK, it will be a wonder-worker. The three additional nutrients are calcium, Magnesium, and Sulfur.

Micro-nutrients

The addition of micronutrients in the fertilizer works well for plant growth. Micro-nutrients include boron, copper, iron, molybdenum, zinc, chlorine, and manganese. These micronutrients are needed by the plants in tiny amounts.
