Key facts

Care Guide

Detailed care guide

Begonia is a charming flowering plant that blooms beautifully indoors. With many varieties available, it can brighten up the mood of any home.

Watering

Water it once the top of the soil has dried. Be careful not to get water droplets on the leaves. Overwatering can turn the leaves yellow or mushy, while dryness can cause the leaf tips to brown.

Light

It grows well in bright indirect light or gentle direct sunlight. Without enough light, the stems can stretch out and grow leggy. Overly strong direct sunlight can damage the leaves.

Humidity

Begonia likes moderate to high humidity. If it's too dry, the leaf tips can dry out or turn brown, so keep humidity up while maintaining good airflow.

Temperature

A range of 15–25°C is ideal. Temperatures outside that range can hinder growth. It's best to avoid sudden temperature changes.

A common first-timer mistake

Watering too often even when the soil isn't dry yet is a common mistake. Watering only after the soil surface has fully dried can help prevent overwatering.

If you have pets

If pets eat begonia, it can cause mild symptoms like vomiting or diarrhea. Keep it somewhere they can't reach or chew on.

Season by season

From spring through fall, it grows and flowers actively. During this period, a flowering fertilizer about every other week works well. In winter, growth slows, so skip fertilizer and space out your watering more.

Common problems and fixes

If the leaves turn yellow or mushy, that can be a sign of too much water. Browning leaf tips can suggest dryness or low humidity. Without enough light, the stems can stretch out and throw off the plant's overall shape, so move it somewhere brighter.

Repotting and propagation

The soil needs to drain well and be fertile for healthy root growth. Repot every few years, replacing the soil once the roots have filled the pot. To propagate, cut a healthy stem and plant it in fresh soil.

Who it's a good fit for

This plant is great for anyone who wants to add a decorative accent to a space or enjoy flowers indoors. If you're not confident about managing moisture, or plan to be away from home for long periods, think it over carefully first. Since it's not difficult to care for, beginners can give it a try too.
