WaterThe Black Knight Begonia should be watered regularly to keep its soil consistently moist but not saturated. It's important not to let the plant sit in water as this can lead to root rot. Generally, water this Begonia when the top inch of soil feels dry to the touch, which may equate to watering once a week, but this can vary depending on the environment and the size of the pot. A moderate amount, like about 8-16 ounces for a medium-sized pot, is usually sufficient. During the winter months, reduce watering as the plant enters a dormancy period and its growth slows down.
LightBlack Knight Begonia thrives in bright, indirect sunlight. Direct, harsh sunlight can scorch its leaves, while too little light can cause the plant to become leggy and affect its rich foliage color. A spot near an east or north-facing window where it can receive plenty of diffused light is ideal. If natural light is insufficient, supplement with grow lights to maintain vibrant leaf coloration and overall plant health.
TemperatureThe ideal temperature range for Black Knight Begonia is between 60°F and 75°F. They can tolerate a minimum temperature of around 50°F, but cold drafts and temperatures below this can be damaging to the plant. They should not be exposed to temperatures above 86°F as excessive heat can stress the plant. Keeping Begonias in a consistent temperature range without fluctuations is key to their health.
PruningPruning Black Knight Begonia helps maintain its shape, encourage bushier growth, and remove any dead or yellowing leaves. Pruning is best done in the spring or early summer when the plant is beginning a period of active growth. Remove spent blooms and trim back leggy stems to encourage more compact growth. Generally, light pruning can be done throughout the growing season to keep the plant looking its best.
CleaningAs needed
SoilThe best soil mix for Black Knight Begonia is a well-draining, peat-based potting mix with added perlite or vermiculite. The ideal soil pH should be slightly acidic to neutral, ranging from 5.5 to 6.5.
RepottingBlack Knight Begonias should be repotted every 1-2 years or when they outgrow their current pots, ideally in spring or early summer.

Life cycleThe Begonia 'Black Knight' begins its life cycle as a seed or from a cutting. Once germinated or rooted, the seedling grows into a juvenile plant with distinct dark, almost black foliage. As it matures, the plant develops a strong stem and lush leaves, entering its vegetative stage. During this stage, the plant focuses on leaf and stem growth. Eventually, the Begonia 'Black Knight' reaches sexual maturity and produces flowers, typically during the warmer months. After pollination, the plant produces seed capsules, and once these capsules ripen, the seeds are dispersed, starting the next generation.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagating the Begonia 'Black Knight' is through leaf cuttings. This can be done at any time of the year but is most successful when performed in spring or early summer when the plant is actively growing. To propagate by leaf cuttings, select a healthy mature leaf and cut it into pieces, each section having at least one of the main veins. Dip the cut edge of the leaf piece into rooting hormone powder to encourage root growth. Then, lay the leaf sections onto a well-draining potting mix, barely covering the cut edge with the soil. Maintain the humidity around the cuttings by covering them with a plastic bag or placing them in a propagator and keep in indirect light until new plants begin to grow from the veins, which typically occurs within several weeks. After new growth is established, individual young plants can be carefully separated and potted up.
