During the day or at night, combine the lighting to let Strelitzia regia receive the light irradiation. Each square meter can be equipped with a 100 watt incandescent lamp, which is better to hang 50 cm above the plant. Although Hewanglan likes strong light, such light conditions can basically meet its requirements. If possible, it can also be transferred to the outside when the sun rises in the morning, so that it can receive the direct sunlight which does not feel very hot on the hand, which is conducive to the growth of the plant.
Generally speaking, the ambient temperature of the basement in summer can be kept between 15 ℃ ~ 25 ℃, which can ensure that Strelitzia can continue to grow rapidly in summer. If it's too hot outside, you need to close the door for heat preservation, otherwise the environment temperature of the cultivation site suddenly becomes very high, and the growth speed of the plant will be greatly affected.
If the maximum temperature in summer has reached 25 ℃, if possible, it can be transferred to the basement with room lamp for management. It's better to put the Hewanglan basin directly on the ground. It's cooler and more convenient to water
In addition, because the air in the basement is not very circulating, it is necessary to control the amount of water to prevent root rot. Every other week, the thin fertilizer water made of all vegetable flower flake fertilizer made of inorganic salt is applied. At this time, it is more suitable to use inorganic fertilizer, which not only has quick effect, but also is clean. When the weather turns cool and the maximum temperature is lower than 25 ℃, let it gradually accept more direct sunlight. These "low temperature summer" Strelitzia, and in the normal conditions of Strelitzia, not only the leaves significantly increased, but also more robust petiole.
