Some time ago, some flower friends asked Xiaojie in the forum, "when the fire sacrifice was last summer, the color of outdoor sun exposure was still green. What should I do this year?" , seeing this problem, compared with the flower friends, they already know whether the fire sacrifice can be dried.
Yes, fire sacrifice is a summer type species, summer will not enter the dormancy period, so it is good to sun more. But the high-rise bedroom or closed balcony, or the environment of continuous high temperature, should pay attention to ventilation, appropriate shade at noon in summer, to avoid excessive exposure to the sun.
First of all, you should understand the principle of red fire sacrifice. Low temperature + drying + sunlight are the three conditions for red fire sacrifice. Therefore, in summer, only one of the conditions, humid and high temperature environment, will not change the color of the fire sacrifice.
So we don't have to worry about how the sun burned for so long in summer, how can it not be red at all? In summer, sun exposure is only to meet the needs of normal growth, to avoid excessive growth due to lack of sunlight.
Fire sacrifice to red, to see how the winter sun, but also pay attention to how to raise summer! Although before turning red, the fire sacrifice will experience hot summer and cold autumn, this is the time for the fire sacrifice to store nutrients.
In summer, we should focus on the cultivation of roots, so that the fire sacrifice can grow rapidly. A large amount of nutrients are stored in the body of the fire sacrifice. After the temperature drops in autumn, the water will be cut off gradually, and the water will be sprayed instead of watering. The fire sacrifice will become more and more red in the whole day according to the maintenance.
In addition, we need to pay attention to the small details of fertilizer application, avoid concentrated fertilizer, and have certain requirements on the selection of no fertilizer, so as to reduce the content of nitrogen fertilizer, otherwise the plant will grow in vain and the leaf color will not be red. The fertilizer is mainly P-K fertilizer, which can be applied once a month.
