Growing Begonias


Begonias are versatile and can be grown indoors and outdoors, depending on your climate.

You can also start from a  seed, cutting, or tuber.

However, selecting the right Begonia for your climate and location is the first step to ensuring a good harvest.

Here’s how to grow Begonias.

Choose the Right Type of Begonia

Many begonias exist but can be classified into four or five main groups:

  • Fibrous
  • Tuberous
  • Rhizomatous
  • Hardy
  • Rieger

Each group has different characteristics and preferences for light, temperature, and moisture.

For example:

  • Fibrous begonias are good for containers and hanging baskets.
  • Tuberous begonias have large and showy flowers.
  • Rhizomatous begonias have interesting foliage patterns.
  • Hardy begonias can survive cold winters.
  • Rieger begonias have rose-like flowers.

You should choose a type of begonia that suits your garden or indoor space and your climate.

Most begonias are tropical or subtropical plants that need warm and humid conditions.

They are usually grown annually in cooler regions or as houseplants that must be brought indoors during winter.

Prepare the Soil and Pots

Begonias like acidic, well-drained soil that is rich in organic matter.

You can use a peat-free, multi-purpose compost or a potting mix that contains peat moss and perlite.

Add some slow-release fertilizer or organic matter, such as leaf mold or compost, to provide plant nutrients.

If you plant begonias in pots, ensure they have drainage holes and a saucer to catch excess water.

Use a gravel or broken pottery layer at the bottom of the pot to improve drainage.

Pot Size

Choose a pot size appropriate for your type of begonia.

For example, fibrous begonias need small pots (4-6 inches, 10-15 cm), tuberous begonias need medium pots (6-8 inches, 15-20 cm), and rhizomatous begonias need large pots (8-10 inches, 20-25 cm).

Sowing, Transplanting, and Propagating Begonias

Depending on the type and availability, you can start begonias from seeds, cuttings, or tubers.

Seeds are usually used for fibrous and Rieger begonias, cuttings for cane and angel-wing begonias, and tubers for tuberous begonias.

Here are some general guidelines for each method.


Sow seeds indoors in late winter or early spring.

Use a shallow tray filled with moist potting mix. Sprinkle the seeds lightly over the surface, and do not cover them.

Place the tray in a warm (70-75°F, 21-24°C) and bright location but out of direct sunlight.

Keep the soil moist but not soggy.

Germination should occur within 2-3 weeks. Transplant the seedlings into individual pots when they have 2-3 true leaves.


Take cuttings from healthy stems in spring or summer.

Use a sharp knife or scissors to cut a 3-4 inch (7.5-10 cm) piece below a leaf node.

Remove the lower leaves and dip the cut end in the rooting hormone if desired. Insert the cutting into a small pot filled with moist potting mix.

Place the pot in a warm (70-75°F, 21-24°C) and bright location but out of direct sunlight. Keep the soil moist but not soggy.

Rooting should occur within 4-6 weeks.


Plant tubers indoors in late winter or early spring.

Use a medium-sized pot filled with moist potting mix. Place the tuber on the surface with the concave side up.

Cover it lightly with soil so that only the top is visible.

Place the pot in a warm (70-75°F, 21-24°C) and bright location but out of direct sunlight. Keep the soil moist but not soggy.

Sprouts should appear within 2-4 weeks.

Remember to water newly planted begonias gently and avoid overwatering, as excessive moisture can lead to rot.

How To Care for Begonias?

Yellow begonia

Begonias are not very demanding plants but need basic care to keep them healthy and blooming.

Here are some tips on how to care for your begonias.

Water Regularly

Water your begonias thoroughly once a week or when the soil’s top half-inch (1 cm) feels dry.

Avoid overwatering, as this can cause root rot.

Use a watering can with a narrow spout to water the base of the plant and avoid wetting the leaves and flowers.


Fertilize your begonias monthly with a balanced liquid fertilizer diluted to half strength during the growing season.

Alternatively, you can use a slow-release fertilizer pellet in the potting mix when planting.

Do not fertilize during winter, when the growth slows down or stops.


Prune your begonias regularly to remove dead or damaged leaves and flowers.

Pruning will encourage new growth and prevent diseases.

You can also pinch off the tips of young stems to promote bushier plants.

Use sharp scissors or pruners and sterilize them before and after use.

Begonias Like Bright but Indirect Light

Place them on windowsills that face east or west, where they get several hours of sunlight each day.

Avoid direct sunlight, especially in summer, as this can scorch the leaves and flowers.

You can also use fluorescent or grow lights for indoor begonias, keeping them 6 to 12 inches (15-30 cm) above the plants and on for 12 to 14 hours a day.

Begonias Prefer Warm and Humid Conditions

The ideal temperature range for most begonias is 65 to 70°F (18 to 21°C).

Avoid exposing them to cold drafts or extreme temperatures, as this can stress them and cause leaf drops.

You can increase the humidity around your begonias by misting them occasionally, placing them on a tray of pebbles and water, or using a humidifier.

When Do Begonias Bloom?

Begonias bloom from late spring to frost, depending on the type and climate. Tuberous begonias planted in February bloom in June, while those planted in March or April bloom in July. Some varieties can bloom all year long indoors.

Possible Problem Growing Begonias

Begonias are generally easy to grow, but they can face health and appearance problems.

Here are some of the possible problems you may encounter when growing begonias.

Yellowing Leaves

Overwatering, nutrient deficiencies, or insufficient light can cause yellowing leaves in begonias.

Adjust watering practices, fertilize regularly, and provide adequate light.

Leaf Spots and Blight

Fungal or bacterial infections can cause leaf spots and blight.

Remove affected leaves, improve air circulation, and avoid overhead watering.

Treat with appropriate fungicides if necessary.

Powdery Mildew

Powdery mildew appears as a white powdery coating on leaves.

Improve air circulation, avoid overcrowding, and apply fungicidal sprays as needed.

Wilting and Root Rot

Overwatering and poorly drained soil can lead to root rot and wilting.

Adjust watering frequency, ensure proper drainage, and repot if necessary.

Pest Infestations

Common pests include aphids, mealybugs, and spider mites.

Use insecticidal soap or neem oil, manually remove pests, or introduce beneficial predators.

They are easy to grow and maintain if you provide the right conditions and care.
