Begonia Care

Begonias are vibrant, hearty plants that thrive with proper care. They add splashes of color to your garden or home with their diverse leaf shapes and flower patterns. To ensure they flourish, you must understand their specific needs ranging from light conditions to soil type. In this guide, you’ll learn the essential care techniques for nurturing begonias that will help them grow healthy and strong.

Scientific Classification

Every plant, including the Begonia, has a unique scientific classification. Think of it like an address that gives its exact location in the plant world. Here’s the breakdown for Begonias:

  • Kingdom: Plantae
  • Phylum: Tracheophyta
  • Class: Magnoliopsida
  • Order: Cucurbitales
  • Family: Begoniaceae
  • Genus: Begonia
  • Species: Multiple species of begonia (rex begonia, angel wing begonia)


Begonias need bright, indirect sunlight to grow well. This means you should place them near a window that gets lots of light, but not where the hot sun rays can hit them directly. Direct sunlight can burn their leaves, causing them to turn brown and crispy. If you notice that the leaves are getting too much light, they may look faded or have dry, scorched patches. On the other hand, if there’s not enough light, their leaves might become thin and the plant could stop flowering. A good spot is often a few feet away from a sunny window or in a room with a sheer curtain that diffuses the light. It’s important to find the right balance for your begonia to make sure it stays healthy and happy.


Water is crucial for keeping your begonia healthy. You should give your begonia enough water, so its soil is moist but not soggy. Let the top inch of soil dry out before watering again. Over-watering can lead to root rot, which is harmful. In warmer months, your begonia might need more water. Always check the soil moisture first. Use room temperature water to avoid shocking the plant. Less water is needed during winter when the plant is not growing much. Remember, your begonia’s watering needs can change with the seasons.


When you grow begonias, the soil is like their home. It needs to be just right for them to thrive. Imagine wearing shoes that don’t fit—you wouldn’t be comfortable. Similarly, begonias need soil that suits them. This soil should be light and well-draining, like a sponge that holds enough water but also lets the extra drip away. It should be rich in nutrients, which are like food for the plant. The soil’s pH, which tells if it’s acidic or alkaline, should be slightly acidic to neutral. That means the pH should be between 5.5 and 6.5. If the soil is too heavy or doesn’t drain well, your begonias might get too much water around their roots. This can cause root rot, which is bad for them. So, pick the right soil, and your begonias will have a comfortable home to grow in.


Begonias like to be warm. They thrive in temperatures between 60 and 75 degrees Fahrenheit. If it gets too hot, above 85 degrees, begonias can become stressed. They don’t like the cold either. Temperatures below 50 degrees can harm them. Keep your begonia away from drafty windows or doors in the winter. It’s also important to avoid sudden temperature changes. Don’t put your plant near heaters, stoves, or air conditioners. These can create hot or cold spots that are not good for the begonia. Therefore, finding a place in your home that stays consistently warm is best for your plant. Remember, steady warmth keeps begonias happy.


Humidity is the amount of water vapor in the air. Begonias like it when the air is a bit moist, like in a bathroom after a hot shower. However, they don’t like it too wet or too dry. Your begonias will thrive when the room feels comfortable to you, not too sticky or dry. If the air in your home is dry, you can use a spray bottle to mist your begonia’s leaves. Be careful though—too much mist can lead to problems like fungus. You can also place a tray with water and pebbles under the plant pot. This will lift the pot above the water and add moisture to the air as the water evaporates. Keeping your begonia happy with the right humidity levels is important for its health and beauty.


Fertilizer is like a vitamin boost for your begonia. It gives your plant the extra food it needs to grow well. Imagine you are eating only water and salad every day; soon, you’d need more nutrients. That’s how your begonia feels. You should use fertilizer during the growing seasons, which are spring and summer. Do not fertilize in the fall and winter because that’s when your plant is resting. There are many kinds of fertilizers, but the ones that dissolve in water are best for begonias. Use them every couple of weeks, following the instructions on the package for the right amount. But be careful not to overdo it; too much fertilizer can harm your begonia. It’s like having too much of a good thing.

Size & Growth Rate

Begonias come in many sizes, with some staying small and others growing large. The rate at which they grow can vary too. Some begonias grow slowly, taking their time to reach their full size. Others might grow faster, filling out their space quickly. The growth rate often depends on the type of begonia and the care you provide. Good light, proper watering, and the right temperature can help your begonia grow well. If your begonia is happy, you might see it grow several inches each year. But remember, each type is different, so your begonia’s growth may not match that of another.

Common Issues

Begonias are hardy plants, but they can face problems like any other houseplant. Sometimes leaves may turn yellow or brown. This could be due to too much sun or not enough water. Pests such as mealybugs, spider mites, and fungus gnats can also bother your begonia. These small bugs suck on plant juices or damage roots. If you see a sticky residue on the leaves or tiny webs, you might have pests. Overwatering your begonia can cause root rot, where the roots start to decay. If the leaves get spotted or look burnt, your plant might have a fungal infection. Take care to avoid these common issues by checking your plant regularly and adjusting care as needed.


Begonias, while beautiful, can be harmful if eaten. They contain substances that are toxic to both people and pets. These substances can cause irritation in the mouth, throat, and stomach. Symptoms of poisoning might include vomiting, salivating more than usual, or swelling. It’s important to keep begonias out of reach, especially from curious animals or small children who might try to eat the plant. If someone does eat part of a begonia, it’s best to get help from a doctor or a poison control center right away. Always handle these plants with care and make sure to wash your hands after touching them. This will help avoid any potential issues from the plant’s toxicity.

Pro Tips

When you care for Begonias, think about these helpful hints:

  • Rotate your Begonia regularly so that each side gets its fair share of light.
  • Keep your plant away from drafts or vents to avoid sudden temperature changes.
  • When watering, water thoroughly but let the soil dry out a bit between sessions.
  • Check the moisture by sticking your finger an inch into the soil; if it’s dry, it’s time to water.
  • Clean the leaves with a soft, damp cloth to remove dust and help the plant breathe.
  • Provide some shade during the hottest part of the day if your Begonia gets direct sunlight.
  • If your Begonia stops blooming, give it a break with less water and no fertilizer for a while.
  • Remember to repot it every couple of years to give it fresh soil and more room to grow.
