Soil Requirements
Begonia meyeri-johannis auct. prefers well-draining soil that is rich in organic matter. A mix of peat moss, perlite, and vermiculite is ideal. The soil should also have a slightly acidic pH of 6.0 to 6.5. Avoid using soils that are heavy and retain water, as this can cause root rot.
Cultivation Methods for Begonia meyeri-johannis auct.

Watering Needs for Begonia meyeri-johannis auct.
Begonia meyeri-johannis auct. requires regular watering, so make sure the soil is evenly moist. However, be careful not to overwater as this can lead to root rot. The best way to check soil moisture is by sticking your finger in the soil up to your first knuckle. If it feels dry, it's time to water.
Fertilization for Begonia meyeri-johannis auct.
Since Begonia meyeri-johannis auct. is a heavy feeder, it needs a regular supply of nutrients to thrive.

Make sure to dilute the fertilizer to half its recommended strength before applying it to the soil.
Pruning for Begonia meyeri-johannis auct.
Pruning helps to keep your Begonia meyeri-johannis auct. healthy and well-shaped. You should trim back any dead or damaged leaves or branches as soon as you notice them. To encourage bushier growth, you can also pinch back the stem tips in spring and early summer. This will encourage the plant to produce more lateral shoots and create a fuller appearance.
Propagation of Begonia meyeri-johannis auct.
Begonia meyeri-johannis auct. can be propagated through several methods including leaf cuttings, stem cuttings, and division.
Leaf Cuttings
Leaf cuttings are a popular method of propagating Begonia meyeri-johannis auct. To take leaf cuttings, select a healthy leaf that has a petiole attached. Cut the leaf with a sharp knife, making sure the cut is clean and straight. Dip the cut end of the petiole in rooting hormone and plant it in a pot filled with moist potting soil. Keep the soil moist and warm, and the cutting should root in a few weeks.
Stem Cuttings
To take stem cuttings, select a healthy stem that has several leaves attached. Cut the stem with a sharp knife, making sure the cut is clean and straight. Dip the cut end of the stem in rooting hormone and plant it in a pot filled with moist potting soil. Keep the soil moist and warm, and the cutting should root in a few weeks.
Division
Another method of propagating Begonia meyeri-johannis auct. is through division. To divide the plant, carefully remove it from its pot and gently pull the roots apart. Each section should have a good amount of roots and several stems with leaves. Plant each section in its pot with fresh potting soil and water thoroughly.
Management of Disease and Pest in Begonia meyeri-johannis
Begonia meyeri-johannis, also known as Meyer's begonia or ‘Jurassic Pink,’ is a beautiful, low-growing houseplant with glossy foliage and delicate pink flowers. However, like any other plant, it is susceptible to various diseases and pests that can damage its growth and development. Here are some common diseases and pests that might affect the plant and ways to manage them:
Common Diseases
One of the common problems that begonias face is powdery mildew, which appears as a white, powdery substance on the leaves and stems. It is caused by the fungi Oidium begoniae and can lead to yellowing leaves, wilting, and stunted growth. To manage powdery mildew, you can use a fungicide spray or remove the infected parts of the plant.
Another disease is Botrytis blight, caused by the fungus Botrytis cinerea that causes brown patches on leaves and stems. It thrives in cool, damp conditions and can produce a gray, fuzzy growth on the plant. To treat this, improve air circulation around the plant, and remove any infected parts before applying a fungicide.
Common Pests
Common pests that affect Begonia meyeri-johannis include spider mites, mealybugs, and thrips. Spider mites are tiny pests that suck the sap from the leaves and cause webbing between leaves. Mealybugs resemble small, white cotton balls and feed on the plant sap. Thrips are slim pests that feed on the leaves, causing discoloration and disfigured growth.
To manage pests, you can use insecticidal soaps or horticultural oils that kill pests on contact. You can also remove the pests manually by wiping the affected areas with a cotton ball soaked in rubbing alcohol.
Conclusion
Begonia meyeri-johannis is a beautiful plant that requires proper care to remain healthy and free of diseases and pests. By keeping the plant clean, providing sufficient light and water, and watching out for signs of disease or pest infestation, you can protect your plant’s growth and enjoy its beautiful pink blooms all year long.
