The Begonia ‘Criss Cross’ is a captivating houseplant known for its striking foliage. Its unique leaf patterns and vibrant colors make it a popular choice for indoor plant enthusiasts.
Understanding Begonia Criss Cross
The Begonia ‘Criss Cross’, also known as the Iron Cross Begonia (Begonia masoniana), features distinctive heart-shaped or ovate leaves. These leaves display a vibrant bright green base adorned with a prominent, dark chocolate-brown pattern resembling an “iron cross” in the center. The foliage often has a thick, rough texture, sometimes described as puckered or bullate, and is covered in soft, velveteen hairs. This plant typically exhibits a compact, mounded growth habit, reaching a mature height of about 12 to 18 inches.
Begonia Criss Cross Care Guide
Light
Begonia ‘Criss Cross’ thrives in bright, indirect light. An ideal placement is near an east or north-facing window, where it receives ample light without harsh exposure. Direct sunlight can scorch the leaves and cause the distinctive central pattern to fade. Conversely, insufficient light may lead to leggy growth and dull leaf coloration.
Watering
Allow the top one to two inches of soil to dry completely before watering. Ensure the soil is thoroughly saturated, allowing excess water to drain freely from the pot’s bottom to prevent waterlogging. Overwatering can quickly lead to root rot. During cooler winter months, reduce watering frequency as the plant’s growth naturally slows.
Soil and Potting
A well-draining soil mix rich in organic matter is ideal for Begonia ‘Criss Cross’. An all-purpose indoor potting mix amended with perlite and orchid bark ensures adequate drainage and aeration. A terracotta pot can also assist in wicking away excess moisture from the root zone. Repotting is recommended every one to two years in spring, or when the plant outgrows its current container, moving it to a pot only one size larger.
Temperature and Humidity
Begonia ‘Criss Cross’ prefers warm temperatures, ideally between 60°F and 85°F (15°C to 29°C), though it can tolerate warmer conditions up to 100°F (38°C). It is sensitive to cold; avoid temperatures below 55°F (13°C). High humidity, specifically 50% or higher, is beneficial. To increase ambient humidity, consider placing the pot on a pebble tray, grouping plants, or using a room humidifier. Avoid misting leaves directly, as water on foliage can encourage fungal issues.
Fertilizing
During its active growing period in spring and summer, feed your Begonia ‘Criss Cross’ monthly. Use a balanced liquid fertilizer diluted to half strength, such as a 1-1-1 or 10-10-10 NPK ratio. Reduce fertilization or stop entirely during dormant winter months. If the plant is not producing new leaves, it does not require additional feeding.
Propagating Begonia Criss Cross
Propagating Begonia ‘Criss Cross’ is done through stem or leaf cuttings. For stem cuttings, select a healthy segment four to six inches long, cutting just below a node. Remove lower leaves, leaving two or three at the top. Cuttings can be rooted in moist potting mix or a glass of water.
For leaf cuttings, snip a healthy leaf and insert its petiole into moist soil. Place cuttings in a warm location with bright, indirect light and good humidity. Roots typically form within a few weeks, after which new plantlets emerge from leaf cuttings. Ensure the rooting medium provides adequate drainage.
Common Problems and Solutions
Brown or crisp leaf edges often indicate low humidity or insufficient watering. Yellowing leaves can signal overwatering or poor drainage. Stunted growth or fading patterns suggest too little light.
Root rot is caused by prolonged waterlogged soil; ensure proper drainage and use a well-aerated potting mix. Powdery mildew appears as white spots, especially with high humidity and poor air circulation. Improve air circulation and avoid overhead watering.
Pests such as spider mites, mealybugs, aphids, thrips, and whiteflies can affect Begonia ‘Criss Cross’. Spider mites often leave fine webs, while mealybugs appear as cottony clusters. Regularly inspect your plant for early signs of infestation, and treat promptly with insecticidal soap or neem oil.
