How to Grow Dieffenbachia seguine (Dumb Cane)? Detailed Guide to Cultivation Methods and Precautions
I. Cultivation Methods
1. Temperature
It is truly very sensitive to cold. In winter, the temperature should ideally be above 8 degrees to allow it to survive the winter safely; otherwise, cold damage will occur. In particular, if the temperature drops below zero, the plant will die outright. Generally, the most suitable temperature for its growth is between 18 and 30 degrees, so the temperature must be well regulated.
2. Light
It is also very afraid of direct sunlight and often grows in shaded areas. Even short periods of sunlight are not acceptable, because this will cause its leaves to turn yellow and withered. So it is quite different from other plants - it strongly dislikes light, and it is precisely for this reason that it is suitable for growing indoors.
3. Water
This is a point that requires great attention. If it is summer, we should spray a little water on its leaves both morning and evening, and also spray a little on the ground around the plant. This will not only lower the temperature but also increase humidity.
In spring and autumn, when watering, check how dry the potting soil is. If it is not dry, do not water; if it is dry, water it appropriately. After entering winter, we should reduce watering, because if the potting soil is too moist at this time, it will cause its roots to rot.
4. Fertilizing
Generally, when first planting it, we need to apply a little base fertilizer. Then during the growing season, that is, spring and autumn, we can apply fertilizer once about every half month to meet the nutrients needed for its growth. After that, in summer and winter, we no longer need to continue applying fertilizer. Otherwise, it will have the opposite effect.
5. Soil
It very much likes to grow in loose, fertile, well-drained soil and is not tolerant of saline-alkaline conditions. Generally, when choosing potting soil, the most commonly used mix is leaf mold, garden soil, plus a small amount of river sand blended together. This can meet its growth needs and allow it to grow even better later.
II. Precautions
Although it is very attractive, note that its sap is toxic, so you must never touch it with your hands, otherwise it will become very itchy.
