What are the cultivation methods and precautions for potted evergreen (Dieffenbachia)?

Evergreen is very common in our lives. There are many varieties of evergreen; what we usually call evergreen is just the general name for this large category. Common evergreen varieties include Dieffenbachia (spotted dumb cane), gold-edged evergreen, silver-edged evergreen, Guangdong evergreen (Aglaonema), spotted-leaf evergreen, and star-of-Bethlehem (Ornithogalum). Want to know if they are the same as the evergreen you know? Let's enjoy the following pictures of evergreen together.

How do you grow evergreen? What are the cultivation methods and precautions for evergreen? Next, the editor will introduce them to you~~

How do you grow evergreen? First, you need to understand its growth habits. Evergreen likes to grow in damp places under forests or in grasslands. It likes semi-shade, warm, humid, and well-ventilated environments; it is not drought-tolerant and is slightly cold-tolerant; it avoids direct sunlight and waterlogging. It can generally be cultivated in garden soil, but the best is slightly acidic sandy loam rich in humus, loose, and with good water permeability.

Now most families use potted evergreen. The main cultivation methods and precautions for potted evergreen are as follows:

Cultivation methods

1. Soil: It is advisable to use sandy loam rich in humus as the growing medium. Keeping the soil pH at 6~6.5 is more conducive to its full absorption of nutrients.

2. Evergreen likes a semi-shaded, warm, and ventilated environment, so the temperature generally must be kept above 10°C. Except for Aspidistra, which is slightly cold-tolerant, other varieties need to be kept at 10°C~32°C. In winter, it can be kept in full sun; in summer, direct sunlight must be strictly avoided.

3. Water and fertilizer regulation: Evergreen likes moisture and is not drought-tolerant, but watering is best done when the surface of the potting soil looks dry. Too much moisture will rot the roots (the roots are generally fleshy), and in drought, it may wilt due to high transpiration. Fertilization is generally carried out from spring when the temperature rises to 18°C; no fertilization is needed during high summer temperatures or low winter temperatures.

4. Dust cleaning: If you want evergreen to grow well and have green leaves, promptly clean and wipe off the dust on the leaves.

5. Pruning and repotting: As the evergreen plant grows larger, to maintain a good plant shape, its old basal leaves should be pruned frequently.

6. Pest and disease control: When the evergreen clump becomes too dense, it will lead to poor ventilation, and at this time it is prone to damage by scale insects, so everything should focus on prevention. If scale insects are found, you can use 50% malathion emulsion at 1000-1500 times dilution and spray once every 7 days; after 2-3 consecutive sprays, the scale insects can be eliminated.

Precautions

1. Evergreen is a plant with fleshy roots, and waterlogging can easily cause damage; too much watering can easily cause root rot.

2. If evergreen shows yellowed and scorched leaf tips in winter, or even the whole plant withers, it is mainly caused by the roots being unable to absorb water, which affects growth.

3. When growing evergreen indoors, keep it warm, humid, and in a semi-shaded environment. In summer, when growth is vigorous, it needs to be placed in a shaded area to avoid strong light, otherwise it is easy for leaf tips to dry and leaf edges to scorch, affecting the ornamental effect.
