Begonias are lovely plants with dazzling foliage. Think unique leaf shapes, stripes, or polka dots and boldly colored undersides! Native to tropical and subtropical areas, Begonias can be found throughout Central and South America, Africa, India, and Asia. These plants can be demanding, so they’re not exactly easy to grow; at least, they may not be at first. Once you get a handle on Begonia care, these lovely houseplants can be easy to maintain.
Types of Begonia
Begonias are divided into three categories, depending on their root system: tuberous, fibrous, and rhizomatous. Tuberous Begonias have stunning flowers and low-key foliage and are most often grown as landscape plants. Most houseplant Begonias are fibrous or rhizomatous and have eye-catching leaves. Begonia care differs slightly from tuberous to fibrous and rhizomatous, so it pays to know what type of Begonia you have.
Some of the more popular Begonia houseplant cultivars include:
- Angel Wing Begonia (Begonia aconititolia x coccinea)
- Begonia acetosa
- Begonia melanobullata
- Palm Leaf Begonia (Begonia luxurians)
- Pink Spotted Begonia (Begonia amphioxus)
- Polka Dot Begonia (Begonia maculata)
- Rex Begonia (Begonia rex-cultorum)
- Scarlet Begonia (Begonia coccinea)
- Striped Begonia (Begonia listada)
- Wax Begonia (Begonia x semperflorens-cultorum)
Begonia Light Requirements
Houseplant Begonias need bright indirect light. Near a sunny, south-facing window is an excellent location to meet Begonia care light needs. Direct light will burn the lovely foliage or cause the vibrant colors to fade, so keep the plant out of a window or hang sheer curtains to diffuse the sunlight.
How Often to Water Begonia
Begonias prefer consistently damp soil but like to dry out somewhat between watering. Water Begonia plants when the top inch or two of the soil is dry. Root rot is a serious problem for Begonias, so only water when needed. The stems will droop, and the leaves will curl when the plant is dehydrated. Normally, you want to avoid letting the plant dry out too much, but when it comes to Begonia care, it’s fine to let the plant tell you when it’s thirsty if it prevents overwatering.
Best Soil for Begonia
Drainage is vital for Begonia care because while these plants like moisture, too much is a problem. Most potting mixes are suitable but mix in sand or perlite to ensure the drainage meets the Begonia’s needs.
Temperature for Begonia
Warm temperatures are necessary for Begonia plants to thrive. Anything between 60° and 80° F is good. Keep Begonias away from heating or cooling vents to avoid temperature fluctuations. Temperatures below 50° F are too cold, so if you bring your plant outside for the summer, get it back inside well before the weather turns chilly.
Begonia Humidity
Humidity is a big part of Begonia care. All Begonia plants thrive in increased humidity, but fibrous and rhizomatous plants are a bit more adaptable. Tuberous Begonias must have high humidity, and this is part of what makes them more challenging to grow as houseplants. Brown, crispy edges on the leaves indicate the air is too dry. Place Begonias in naturally humid areas of your home or increase the air moisture to support the plants.
Do Begonias Bloom?
Yes, you can expect flowers when your plants receive proper Begonia care. These plants need ideal conditions to bloom, so Begonias grown as houseplants do not always set flowers. Provide excellent care, and you may get to enjoy flowers, although you can always admire the striking foliage. The length of the bloom cycle depends on the type of Begonia, but these beauties can bloom for months at a time.
Begonia Fertilizer
Fertilize established houseplants when they are actively growing. Give your Begonia a rest during the fall and winter when growth slows. Use a balanced fertilizer to support overall growth, especially if the Begonia is grown for its ornamental foliage. Houseplants don’t always bloom, but if you want to encourage blooms on a healthy plant, feed your Begonia using a fertilizer low in nitrogen.
Pruning Begonia
Begonia plants can become overgrown or leggy, so pruning resets the plant, creating a bushier growth habit. Prune or pinch back Begonias to create a well-rounded, consistent shape. Remove dead or damaged growth at any time, but shape Begonias in the spring at the start of the growing season.
When to Repot Begonia
Repotting is an essential part of Begonia care. While these plants like to be somewhat root bound, plan to repot Begonias every two to three years or when the roots poke through the drainage holes in the pot. More frequent watering is another sign a Begonia is ready for a new pot, as root-bound plants quickly soak up the moisture after being watered. Choose a container one to two inches larger when it is time to repot and use fresh soil that allows drainage.
Begonia Propagation
Create new plants by propagating your Begonia via stem cuttings. Begonia cuttings can be propagated in soil or water. Roots will appear in a few weeks. Place the cuttings in bright indirect sunlight and increase the humidity to help the new plants set roots.
Is Begonia Pet Friendly?
Begonia plants are not pet friendly. All parts of all Begonia varieties are toxic to cats and dogs. The roots are more toxic than the stems, foliage, and flowers, but your pet will become ill from eating any part of the plant.
Begonia Styling Tips
Begonia plants are a natural focal point that do not need much help when it comes to looking amazing. Give these plants a subdued planter that will not distract from the showy foliage. Begonias look charming in a concrete or terra cotta planter that will provide a nice contrast against the warmth of the colorful leaves while allowing the soil to dry. Tiny plants look charming on a desk, while large plants create a stately presence on a plant stand.
Begonia Care Tips
Begonias are lovely plants that have gorgeous foliage. Like all tropical and subtropical plants, they like their humidity, but they really are easy to maintain once you get the hang of it. Overwatering is the most likely problem to face these leafy beauties, so only water when necessary.
