WaterThe King Begonia should be watered when the top inch of soil feels dry to the touch, roughly once a week, but this can vary depending on the humidity and temperature of the environment. Use room temperature water, and give the plant enough water so that it runs out of the drainage holes at the bottom of the pot, which might be approximately 16-24 ounces for a medium-sized plant. Allow all excess water to drain away, as King Begonias do not like to sit in waterlogged soil. During the winter or in cooler temperatures, reduce watering to prevent root rot, as the plant will use less water.
LightKing Begonia thrives best in bright, indirect light but can tolerate some shade. Avoid placing it in direct sunlight, especially during the harsh midday hours, as the leaves can get scorched. An east or west-facing window is an ideal spot, providing the plant with the gentle morning or afternoon sun.
TemperatureKing Begonia prefers a warm environment with temperatures ranging from 60 to 75 degrees Fahrenheit but can survive in temperatures as low as 50 degrees Fahrenheit and as high as 85 degrees Fahrenheit. However, the ideal temperature range for vibrant growth and leaf coloration is between 65 and 70 degrees Fahrenheit. Keep away from drafts and sudden temperature changes to maintain its health.
PruningPrune King Begonia to maintain its shape and encourage bushier growth. Trim back any leggy or overgrown stems and remove any dead or damaged leaves. The best time to prune is in the spring or early summer when the plant is in its active growing phase. Pruning can be done every few months or as needed to keep the plant looking tidy.
CleaningAs needed
SoilFor the Rex Begonia, the best soil mix is a well-draining, porous potting mix with perlite or vermiculite to enhance drainage. The ideal soil pH for Rex Begonias should be slightly acidic, around 5.5 to 6.5, to maintain healthy growth and foliage.
RepottingRex Begonias should be repotted every 1-2 years to replenish soil nutrients and to accommodate the growing root system. Choose a container that is slightly larger than the previous one to avoid oversizing, which can lead to water retention and root rot.
Humidity & MistingRex Begonias thrive in high humidity, ideally between 50% to 70%. These tropical plants benefit from a humid environment which can be created by using a humidifier, placing a water tray nearby, or grouping plants together to naturally increase moisture levels.

Life cycleBegonia rex, commonly known as the King Begonia, begins its life cycle as a seed, which germinates to produce a small seedling. The seedling grows into a juvenile plant with characteristic large, colorful leaves that are appreciated for their ornamental value. As the plant matures, it develops a robust underground rhizome from which new shoots can emerge. Periodically, the mature Begonia rex will produce clusters of small flowers, although it is primarily grown for its foliage rather than its blooms. After flowering, the plant can produce seeds if the flowers are fertilized, completing the reproductive cycle. The King Begonia can live for several years, with its rhizome enabling it to survive periods of dormancy and regenerate new growth during favorable conditions.
PropogationPropogation time
Spring-Early Summer
Propogation: Begonia rex, commonly known as Rex Begonia, is most successfully propagated through leaf cuttings, a method that is quite popular due to its effectiveness and simplicity. To propagate Rex Begonia by leaf cuttings, a healthy and mature leaf is chosen and a shallow incision is made on several large veins on the underside of the leaf. This leaf is then placed on moist potting soil and secured using bent paperclips or small stones to ensure contact with the soil, maintaining the humidity. In a warm environment (around 70 degrees Fahrenheit or about 21 degrees Celsius), the cut veins will begin to develop roots and shoots. Subsequently, these new plantlets can be separated and planted individually when sufficiently developed, which typically occurs within a few weeks. This method allows gardeners to produce multiple replicas of the parent plant while maintaining the unique foliage patterns characteristic of Rex Begonia.
