How to Prune Begonias: A Step-by-Step Guide for Beautiful Blooms

Begonias are beautiful, colorful plants that can brighten up any garden or home. Whether you’re new to gardening or have some experience, learning how to prune begonias is a great way to keep them healthy and looking their best. In this guide, we’ll show you simple steps to prune your begonias so they grow strong and produce lots of blooms. Let’s get started!

Do I Need to Prune a Begonia?

Pruning begonias is essential for keeping them healthy and beautiful. Whether you live in a warm, frost-free area where begonias can grow year-round, or a cooler climate where they need winter protection, regular pruning helps.

In warm climates, pruning encourages new growth and more blooms, keeping your garden vibrant. For those in cooler regions, trimming back begonias before bringing them indoors for winter helps manage their size and keeps them healthy as houseplants.

Additionally, let’s not forget that pruning removes dead or overgrown parts, preventing disease and promoting better air circulation.

When to Prune Begonias

The timing of pruning begonias depends largely on your climate. In warm, frost-free areas, it’s best to prune your begonias in the spring. This encourages new growth as the plant enters its active growing season, ensuring a burst of fresh foliage and vibrant blooms. Regular spring pruning helps keep your begonias healthy and well-shaped throughout the year.

In cooler climates, you want to prune in the fall. As temperatures start to dip below 50 degrees F (10 degrees C) in the fall, it’s time to trim back your begonias. This makes them more manageable for bringing indoors, where they can be treated as houseplants through the winter.

Fall pruning also helps remove any damaged or leggy growth, preparing the plant for a healthy start when it’s moved back outside in the spring.

The Tools You’ll Need

To prune begonias, you just need a couple of simple tools: pruning shears and gardening gloves. Pruning shears are important because they help you make clean cuts on the plant, which keeps it healthy and growing well. Make sure your shears are sharp and clean to avoid spreading any plant diseases.

Gardening gloves are also a must-have. They protect your hands from getting scratched or dirty while you work with the plants. Gloves make it easier to handle the delicate stems and leaves of begonias without damaging them.

Keeping Your Begonias in Shape

Regularly check your begonias for any damaged or sick parts. Look for leaves and stems that are discolored or look unhealthy.

  1. Remove Dead or Diseased Parts: Use clean, sharp shears to cut off any brown or damaged areas. Make the cut just below the brown part, at a 45-degree angle, keeping as much healthy green part as possible. If a whole stem is brown, you can cut it off completely, but be careful not to hurt the main stem.
  2. Pinch Off the Tips of the Largest Stems: During the growing season, use your fingers to pinch off the tips of the biggest stems. This will help the plant look better and make other stems grow more evenly.
  3. Pinch Off the Last Two Sets of Leaves on a Tall Branch: On tall branches, pinch off the last two sets of leaves. This will make that stem grow more and help the plant become fuller and healthier.

Pruning for Healthy Begonias

  1. Pinch Off New Growth: A few weeks after planting, use your finger and thumb to remove the ends of small stems that branch off the main stems. This encourages new stems to sprout in place of each one you pinch.
  2. Thin Out Thick Foliage: When your begonia is fully grown and gets bushy, cut off up to a third of its stems. This will help the plant look neat and less overgrown.
  3. Deadhead at the End of Blooming Season: When flowers and buds turn brown and die, remove them using your fingers, pruning shears, or scissors. This helps the plant save energy and focus on producing new flowers and growth instead of seeds.
  4. Cut Back in Autumn: After the begonias finish flowering for the year, use pruning shears or sharp scissors to cut the main stem back to about 4 inches (10 cm). This conserves the plant’s energy over winter so it can grow back strong next year. For winter-flowering begonias, cut them back in spring after they’ve finished flowering.


Taking care of your begonias after pruning is important to keep them healthy and looking their best.

  • Watering is crucial—begonias like soil that’s not too dry or too wet. Aim to water them every two to four days. When it’s hot and dry, you’ll need to water more often; when it’s cooler, you can water less.
  • Fertilizing is also key. If you want lots of flowers, use a fertilizer with more phosphorus once a month. But if you love your begonias for their leaves, use a balanced fertilizer instead. This gives them the right nutrients to stay strong and grow well.
