What are the cultivation tips and uses of Dieffenbachia?
Dieffenbachia is an evergreen shrub-like herb with thick, fleshy stems, and the plant can reach 1.5 m in height. The leaves are large and glossy, borne on the upper part of the stem, elliptic-ovate or broadly lanceolate, with acuminate tips and entire margins, 20-50 cm long and 5-15 cm wide; the broad leaves are dark green on both surfaces, inlaid with dense, irregular spots, markings or blotches in varying colors such as white, milky white and pale yellow; the leaf sheath has a petiole below its near-middle part. The flower stalk emerges from the leaf axil and is shorter than the petiole; the flowers are unisexual, in a spadix inflorescence, and the spathe is elliptic with a tubular lower part.
Dieffenbachia cultivation methods:
1. Soil: The ideal cultivation soil for Dieffenbachia is fertile, loose, well-drained loam rich in organic matter. For potting soil, use a mix of leaf mold and coarse sand, for example 2 parts leaf mold, 1 part sawdust or peat, and 1 part sand.
2. Watering: Dieffenbachia likes moisture and fears dryness, so the potting soil should be kept moist. During the growing season, water thoroughly and spray water around the plant and mist the foliage. If it is not misted for a long time, the leaf surface becomes rough and loses its luster. Soil moisture is best kept alternating between dry and wet; water more in summer, and control watering in winter, otherwise the potting soil will be too wet, the roots will easily rot, and the leaves will turn yellow and wither.
3. Sunlight: Dieffenbachia tolerates shade and fears sunburn. If the light is too strong, the leaf surface becomes rough, and the leaf margins and tips easily scorch, or even suffer large-area burns. If the light is too weak, the yellow-white blotches will turn green or fade. It grows best under bright indirect light, and the leaf colors are then more vivid and beautiful.
4. Temperature: The suitable growth temperature for Dieffenbachia is 25-30°C; the effect is good when the daytime temperature is 30°C and the nighttime temperature is 25°C. The possible growth range is 18-30°C from February to September and 13-18°C from September to February of the following year. Because it is very intolerant of cold, it must be moved into a greenhouse in mid-October. If the winter temperature is below 10°C, the leaves are susceptible to cold damage.
5. Fertilizing: June to September is the vigorous growth period for Dieffenbachia; apply cake fertilizer water once every 10 days, and after early autumn, apply phosphorus and potassium fertilizer 2 more times. From spring to autumn, applying nitrogen fertilizer once every 1-2 months can promote glossy leaf color. When the room temperature is below 15°C, stop fertilizing.
6. Pests and diseases: Dieffenbachia is mainly harmed by bacterial leaf spot, brown spot and anthracnose, which can be controlled by spraying 500 times diluted 50% carbendazim wettable powder. Root rot and stem rot sometimes occur; besides paying attention to ventilation and reducing humidity, spraying 800 times diluted 75% chlorothalonil wettable powder can be used for prevention and control.
