How to cultivate Eustoma
An article about how to cultivate Eustoma and related knowledge of cultivation methods and precautions in the field of floriculture, let's get to know together.
Eustoma is a perennial plant of the Gentianaceae family, which has a relatively wide distribution in China. Eustoma has an elegant plant shape, graceful flower color, and fresh fragrance, making it very valuable for ornamental purposes. It is very suitable for flower arrangement and cut flowers, and is loved by many people. So, how should Eustoma be cultivated? What are the precautions? The following article will provide you with the cultivation methods and precautions for Eustoma, let's take a look!
1. Soil selection and sowing
Although Eustoma is not very demanding on soil, it grows better in soil with good permeability, softness, and rich humus. For pot cultivation, you can choose materials like peat and perlite to make up the potting soil, and消毒 the soil before planting. Then, select the right planting variety according to the planting season. If planting in spring and autumn, choose early-maturing varieties. Before sowing, the seeds should be treated with a seed coating because the seeds are small and like light, so there is no need to cover the soil after sowing. Control the temperature at around 25 degrees, and the seeds can germinate in about half a month. After germination, thinning and transplanting should be done about half a month later.
2. Water and fertilizer management
When cultivating Eustoma, it is necessary to pay attention to watering. However, be sure to control the amount of water, as Eustoma is very sensitive to moisture. Many people sometimes water excessively to meet Eustoma's water requirements, which can lead to excessive water and root damage, causing rot and even triggering diseases and pests. Therefore, it is important to control the amount of water according to the changes in climate and temperature and not to water too much. Eustoma does not require much fertilizer; generally, a low-concentration calcium nitrate liquid fertilizer can be applied. Pay attention to the amount of nitrogen fertilizer, as too much can easily cause excessive branching, tip burning, and stem splitting.
3. Temperature control
About half a month after sowing, Eustoma seeds will emerge from the soil. At this time, we need to pay attention to controlling the temperature. The suitable temperature for Eustoma's growing period is around 16-25 degrees. The daytime temperature should not exceed 25 degrees, and the nighttime temperature should be maintained at about 10 degrees, otherwise, it will severely affect Eustoma's growth. In the seedling stage, Eustoma grows relatively slowly, so it is important to control the temperature and humidity. Avoid high-temperature and high-humidity environments that can cause Eustoma to grow excessively and trigger various diseases. Also, control the intensity of sunlight, as it should not be too weak.
4. Precautions
When caring for Eustoma, temperature is something that needs our special attention, and the temperature must not be too high. Moreover, to enhance the ornamental value of Eustoma flowers, the flower stems should be cut back once every year after flowering to increase the flowering rate of the plant the following year. We also need to pay attention to the prevention and control of diseases and pests, such as stem blight, gray spot disease, and leafminer. Do a good job in daily management, enhance ventilation and light transmission, and control the planting density. When top-dressing, the proportion of phosphorus and potassium fertilizers can be appropriately increased to enhance the plant's disease resistance.
The above is a complete introduction to how to cultivate Eustoma and related cultivation methods and precautions, for everyone to learn and understand!
