1. Light

Like other varieties of the begonia, they are to be placed in a shady spot where they’ll get plenty of bright, indirect sunshine. Early morning sunlight will do the foliage a lot of good, and this should only be for 4- 5 hours. However, generally, do not keep the houseplant in direct sunlight.

2. Water

The water needs of whooper begonia are the same as for other begonia cultivars. Always make sure that your plant is not clogged with water. To ascertain when the whopper begonia plant requires some water, you can check the topsoil and only water it if it is dry.

You can also check for moisture by dipping your finger into the soil before watering.

3. Soil

The whopper begonias prefer soil that is somewhat acidic and drains well. It’s preferable to have less garden soil and more peat moss or cocopeat. The soil should always be moist, but not soggy, to prevent root rot.

4. Humidity

Like other begonia variations, the whooper begonia prefers a slightly higher humidity level. This can range from 75 to 90 percent. When the humidity level is too low, the plants will entirely dry out. In addition, if the humidity is too high, the plant will retain more moisture than is required.

This can result in drooping foliage, disease vulnerability, plant with a drab color, and the production of pests and illnesses.

5. Temperature

The appropriate temperature for the whopper begonia ranges between 60-80F. When the temperature is cooler than this, it will slow down the growth and cause the leaves to droop. When the temperature is high, it can also affect the foliage of the plant. In essence, extreme temperatures are not good for the plants’ growth.

6. Fertilizer

Fertilizing the whopper begonia is essential, as this will aid the fast growth of the plant. Consider fertilizing only during the growing seasons for the best results. Once every 14 days, add a small amount of compost, such as cow dung powder or NPK 20 20 20 crystals, to a pot, roughly 4-6 crystals.

Tips For Growing The Whopper Begonia

Begonias show strong resistance to pests and diseases. However, root rot is a common enemy to all plants, which can be prevented by not making the soil and plant waterlogged.  Here are other growing tips.
