How to Plant Wax Begonias


When growing wax begonias, you can start them from seed or get already established potted plants found in garden centers.

When it comes to starting them from seed, wax begonias are an excellent choice for beginner gardeners. They are accessible to seed both inside and in indoor pots.

When seeding the plant, they need to be spread over nutrient-rich soil and merely be ‘pressed’ into it. The seeds should not be covered.

After planting, the seeds should be in an area with light and provided with adequate moisture.

Because they spawn from tropical regions, the wax begonia flourishes in warm, humid environments. It is essential to ensure that they have a constant source of moisture – if they are exposed to unusually dry or cold conditions, the plant with die.

With this in mind, if you are in an extraordinarily arid or cold environment, consider having potted wax begonias, or plant them early on in the warmer summer months and ensure that they have plenty of water.

As they can also grow in the shade, planting your wax begonias in the shade can help protect them from moisture loss if you live in an arid environment.

Temperature and Climate

The ideal growing temperature for Wax begonias during the day should be around 60 to 75 degrees Fahrenheit.

Wax begonia definitely likes warmer weather.

Most begonias can handle differences in temperatures well. In a frost or arid climate, you face the risk of the plant dying. 

The wax begonia is most widely found in areas that are in USDA hardiness zones 10 or 11.

These include zones a and b, with a general temperature of 35 degrees Fahrenheit and up. They do best in areas that have a late frost date.

The growing season begins in early summer and runs up until the first hard frost.



Wax begonias can handle sun – unlike their begonia cousins, such as tuberous begonias.

However, it depends on the variety of the plant as to how much sun it can tolerate.

If being planted in an area of full sun, the darker bronze or brownish leaf variety does better in the hot afternoon sun.

Otherwise, the green flourishes in partial sun in the afternoon shade. When deciding to plant indoors, the more sunlight that the wax begonia gets, the better.

Window sills are an excellent place for pots or hanging baskets to be placed.

For the begonia, a spot that has morning sun is ideal.


If planted outside, Wax begonias need around 1 to 2 inches of water per week.

Keeping an eye on temperatures and sun conditions is a must.

If there are days when temperatures soar, giving your outdoor begonias, a light mist can protect the large flowers and leaves from dying.

With indoor potted wax begonias, they should be watered when the soil is dry.

Always make sure to keep the soil moist. Keep in mind that the plant should never be in standing water. Ensuring the begonia has well-drained soil will prevent root rot.



While they are relatively low-maintenance plants, Wax begonias do require a bit of pruning.

As they grow, the plant runs the risk of having leaves or stems die off due to the time of year or the temperature and climate conditions.

When dead or dying leaves are spotted, they should be pruned.

Pruning the plant helps keep it healthy and allows it to form new stems with healthier leaves and flowers.

By cutting off dead parts, you can keep wax begonias from getting fungal diseases and powdery mildew, which can kill them.

How to Care for Wax Begonias in the Winter

Before the frost sets in, Wax begonias must be winterized. There are two main methods to winterize them:

  1. They can be transplanted from the ground to a pot and moved indoors.
  2. If the winter climate rarely falls below 60 degrees, simply trimming the plant back so that nothing of the ground can be seen can ensure that the begonia will return the following summer.

Do wax begonias come back every year?

As begonias are both considered perennial and annual plants, they will grow back every year in tropical and sub-tropic climates. In contrast, in cooler weather, they die off after the growing season.
