Care
Regular watering
Water regularly to keep the substrate moist but never waterlogged. Reduce watering in winter. Use soft or filtered water if possible, as this begonia dislikes lime. Avoid wetting the foliage to prevent spotting.
Indirect light
Place it in bright, indirect light, away from direct sun rays that risk burning its delicate leaves. A window facing east or west is ideal. It tolerates slight shade, but growth will be less vigorous.
Aerated and well-draining substrate
Use a mixture rich in organic matter (leaf mold, peat, or coco coir) mixed with perlite or vermiculite to improve aeration. Begonia masoniana needs soil that retains moisture without suffocating the roots.
Moderate fertilizing
Apply a balanced, diluted fertilizer every 15 to 20 days during the growing period (spring-summer). Reduce or stop feeding in fall and winter. Avoid overdosing, which promotes salt accumulation harmful to roots.
Pinching and cleaning
Pinch young stems to encourage a bushy, compact habit. Regularly remove dead or spotted leaves to keep the plant healthy. Light pruning after flowering revitalizes the overall shape.
Watch for pests
Monitor for spider mites and scale insects, especially in dry air. Regular misting of the surrounding air (without wetting the leaves) limits these risks. If infestation occurs, isolate the plant and treat gently.
Did you know?
Begonia masoniana is most famous for its beautifully veined leaves with a silvery-gray hue, resembling a small iron cross embossed on the dark green leaf surface — hence its English nickname 'Iron Cross Begonia.' This raised natural pattern is not a disease, but the result of a fascinating botanical adaptation that optimizes light capture in shaded forest environments.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
