Is Gentiana suitable for indoor cultivation?
If you want to know whether Gentiana is suitable for indoor cultivation and detailed knowledge about the cultivation method of Gentiana indoors, here is the specific introduction:
Gentiana is suitable for indoor cultivation. It prefers humid and cool conditions, and it is more convenient to water, fertilize, and prevent and control diseases and pests indoors. By controlling the indoor temperature and placing it in a location with sufficient scattered light, it can be cultivated indoors. Gentiana is a perennial plant belonging to the Gentiana genus of the Gentianaceae family. Its Chinese name is Longdan, alias Ditan tou. China is one of its original habitats, and it grows wild on the grasslands of the mountainside or under trees, with medicinal value. Below, I will talk about the reasons why Gentiana is suitable for indoor cultivation and the indoor cultivation methods.
I. Reasons for indoor cultivation
Gentiana is suitable for cultivation in a room with sufficient scattered light. Gentiana is afraid of high and low temperatures, but indoor conditions can control the ambient temperature, cool down in summer, and keep warm in winter. Indoor cultivation also makes it more convenient for watering, fertilizing, and managing diseases and pests, making it suitable for indoor cultivation.
II. Methods for cultivating Gentiana indoors
1. Lighting
Seedlings are afraid of direct sunlight and can be kept indoors. Adult plants need sufficient light during the growing season but should be placed in a sunny balcony or outdoors for some sunlight exposure. Gentiana does not tolerate direct exposure to strong sunlight, so the light should not be too strong and should receive moderate direct sunlight. In summer, it can be kept indoors to avoid sunburning the leaves.
2. Temperature
Gentiana prefers cool conditions, with an optimal growth temperature of 20 to 28°C. In most parts of China, Gentiana can grow vigorously indoors in spring and autumn. Gentiana is very sensitive to high and low temperatures. Temperatures above 30°C or below 15°C are not conducive to plant growth. It is best to keep it in a cool indoor environment during the hot season and in a warm indoor environment during winter.
3. Watering and ventilation
Gentiana likes moist soil. Watering should be based on the dryness of the potting soil and should not have waterlogging. In addition to watering, it can also be sprayed in summer when kept indoors. It is also necessary to ensure good ventilation indoors to allow the potting soil to dry normally and prevent diseases and pests caused by high humidity and high temperatures.
4. Soil and fertilization
The planting medium can use soil with good water retention and high humus content, and decomposed chicken manure can be added as a base fertilizer during planting. For daily maintenance, decomposed cake fertilizer water can be applied as a foliar fertilizer. No nitrogen fertilizer should be applied before flowering, only phosphorus and potassium fertilizers.
5. Disease and pest control
The main diseases of Gentiana are Alternaria blight and Sclerotium blight, which often occur in hot and humid environments in summer. It is necessary to promptly cut off the diseased branches, leaves, and plants, and apply medication for prevention. If diseased plants are found, fungicides such as carbendazim or carbendazim can be used for control. The main pests are ants and mole crickets, which can be killed with insecticides.
