Choosing the Right Begonia Variety

Before you start growing begonias, it is important to choose the right variety. There are several types of begonias, each with specific care requirements. Understanding the differences between the varieties will ensure that you can provide the right conditions for your begonias to thrive.

Fibrous-Rooted Begonias

Fibrous-rooted begonias are easy to care for and come in a wide range of colors and sizes. They are ideal for beginners and can be grown both indoors and outdoors. These begonias prefer bright but indirect sunlight and moist soil. To keep fibrous-rooted begonias healthy, make sure to water them regularly and fertilize them every four to six weeks during the growing season.

Tuberous Begonias

Tuberous begonias are known for their large, showy flowers and are often grown as outdoor plants. These begonias thrive in cool, moist conditions and prefer partial shade. When planting tuberous begonias, make sure to bury the tuber with the concave side facing up, about two inches deep in well-draining soil. Tuberous begonias should be watered sparingly until the shoots emerge. Once the plants are established, water them regularly and fertilize every four to six weeks during the growing season.

Rhizomatous Begonias

Rhizomatous begonias are prized for their unique foliage and are often grown as indoor plants. These begonias prefer bright, indirect light and well-draining soil. Rhizomatous begonias can be propagated by division, as they produce new shoots from the rhizome. Water these begonias when the soil is dry to the touch and fertilize every four to six weeks during the growing season.

By selecting the right begonia variety and providing the necessary care, you can enjoy the beauty of these stunning plants in your home or garden. Remember to adjust your care routine based on the specific needs of your begonia variety, and enjoy the process of growing and caring for these lovely plants!

How To Grow And Care For Begonias: Providing the Ideal Growing Conditions

Begonias thrive in bright but indirect sunlight. Placing your begonias in a location where they can receive filtered or dappled light throughout the day is ideal. Direct sunlight can burn the leaves and cause damage to your plants, so it’s best to avoid placing them in an area with intense sunlight.

It’s important to note that different begonia varieties have different light requirements. Some begonias, such as tuberous begonias, prefer more shade than others. Be sure to research the specific lighting needs of your begonia variety.

In addition to proper lighting, begonias prefer moist but well-draining soil. Water them regularly, making sure not to overwater or let the soil dry out completely. A good way to determine when to water your begonias is to stick your finger into the soil- if the top inch is dry, it’s time to water. Overwatering can lead to root rot, so be cautious not to saturate the soil.

A humid environment is also beneficial for begonias. You can increase humidity levels by placing a tray of water near your plants or using a humidifier. Avoid placing your begonias near drafty windows or doors, as this can cause stress to your plants.

Propagating Begonias

Begonias can be propagated in two ways: through leaf cuttings or by dividing mature plants. Both methods require patience and attention to detail, but the rewards are well worth the effort.

Leaf Cuttings

One of the easiest ways to propagate begonias is through leaf cuttings. Choose a healthy leaf from a mature begonia plant and make a clean cut at the base of the stem, just below the leaf blade. Cut the leaf blade into sections, making sure each section has a portion of the stem attached. Then, dip the cut ends in rooting hormone and plant them in a pot filled with moist potting soil. Cover the pot with a plastic bag to create a humid environment and place it in a bright but indirect light. Keep the soil moist and in a few weeks, you should see new growth emerging.

Dividing Mature Plants

If you have a mature begonia plant that has outgrown its container, it may be time to divide it. Carefully remove the plant from its container and gently separate the roots into smaller sections. Each section should have a portion of the stem and several leaves attached. Plant each section into a separate pot filled with fresh potting soil and water thoroughly. Place the pots in a bright but indirect light and keep the soil moist. Your divided begonias should begin to grow and thrive in their new homes.

Begonia Fertilizing Tips

Fertilizing your begonias is crucial for their overall health and growth. However, it is essential to choose the right fertilizer and apply it correctly to avoid over-fertilization, which can damage your plants. Follow these fertilizing tips to ensure your begonias receive the nutrients they need.

Choose the Right Fertilizer

Choose a balanced, water-soluble fertilizer with equal amounts of nitrogen, phosphorus, and potassium (NPK). Look for a fertilizer with a ratio of 20-20-20 or 10-10-10. You can also choose a fertilizer specifically formulated for begonias.

Apply Fertilizer Correctly

Apply fertilizer to your begonias every 4-6 weeks during the growing season, which typically runs from late spring to early fall. Dissolve the fertilizer in water and apply it to the soil around the base of the plant. Make sure to follow the recommended dosage instructions on the fertilizer package.

Reduce or Cease Fertilization

During the winter months, reduce or cease fertilization because begonias typically enter a period of dormancy. Ceasing fertilization will give your plants time to rest and prepare for the next growing season. When spring arrives, gradually resume fertilization to promote healthy growth.

Following these fertilizing tips will help ensure your begonias receive the necessary nutrients for healthy growth and blooming. Remember to check the recommended dosage instructions and avoid over-fertilization, which can harm your plants.

Common Pests and Diseases

Despite the best care, begonias can fall victim to pests and diseases. Here are some common issues to look out for:

AphidsSmall, soft-bodied insects clustering on new growth and buds.Wash them off with a strong jet of water or use insecticidal soap.
Powdery MildewWhite, powdery spots on leaves and stems.Remove infected parts of the plants and treat with a fungicide.
BotrytisBrown spots on leaves and flowers, gray mold on the affected areas.Remove infected parts of the plants and treat with a fungicide.

Preventive measures can help prevent common issues. Avoid overwatering and overcrowding your begonias, and provide good airflow and drainage. Inspect your plants regularly to catch any problems early on.

Follow these tips, and you’ll be equipped to handle any pest or disease that comes your way. Your begonias will thank you for the extra care and attention.

Pruning and Maintenance

How To Grow And Care For Begonias

Regular pruning and maintenance are crucial for the health and appearance of your begonias. Pruning helps to promote bushier growth, remove dead or damaged foliage, and maintain an attractive shape. Here are some tips for begonia care:

  • When pruning, always use clean and sharp tools to minimize damage to the plant.
  • Remove any dead, yellowed, or diseased leaves as soon as you notice them, as they can attract pests and diseases.
  • Pinch back the stems regularly to encourage bushy growth. This is especially important for fibrous-rooted begonias.
  • Deadhead spent flowers to encourage further blooming.
  • Repot your begonias every two years or as needed, using a well-draining potting mix.
  • Groom your begonias regularly by wiping their leaves with a damp cloth to remove dust and prevent pests.

Remember to always wear gloves and avoid contact with the milky sap that begonias produce, as it can cause skin irritation.

Overwintering Begonias

If you live in a region with cold winters, you’ll need to take special care to ensure your begonias survive until the next growing season. Here are some tips for overwintering begonias:

  • Before the first frost, bring your begonias indoors and place them in a cool, dark location for a few days to adjust to their new environment.
  • After a few days, move your begonias to a bright location with temperatures between 60-65°F. South-facing windows are ideal, as they provide enough sunlight to keep your begonias healthy.
  • Reduce watering during the winter months, as begonias require less water when they are not actively growing. Only water when the soil becomes dry to the touch.
  • Stop fertilizing your begonias during the winter months, as they do not need additional nutrients while they are in a dormant state.
  • Inspect your begonias regularly for signs of pests or diseases, as these issues can quickly spread in indoor environments.

By following these simple steps, you can ensure the survival of your begonias during the winter months and enjoy their beauty for years to come. Remember, with a little care and attention, even beginners can successfully overwinter their begonias.


Now that you have learned the basics of how to grow and care for begonias, it’s time to put your new knowledge to the test. Remember to choose the right variety for your growing conditions, provide adequate sunlight and watering, fertilize regularly, and keep an eye out for pests and diseases.
