How to cultivate spring orchids
Do you know about these? The content about how to cultivate spring orchids and the cultivation methods and precautions of green plants and flowers, let's get to know together next.
With the rise of temperature in spring, orchids also begin to sprout new buds and enter a stage of rapid growth. The maintenance management of this stage should also keep up, such as keeping sufficient water and fertilizer, and avoiding direct sunlight. For some varieties whose flowering period has ended, if they have not been repotted and divided for a long time, this period can also be used to replace the planting materials, so that the plants can grow vigorously.
I. Spring Potting
1. The general time for repotting orchids is in spring and autumn, and spring is the period of vigorous growth of the plants. Repotting at this time allows the plants to recover faster. If they have not been repotted for a long time and the seedlings have already filled the pot, you can choose to change the soil in spring. For some varieties that have finished flowering, such as spring orchids and black orchids, you can also divide them at the same time.
When repotting, stop watering a few days in advance to keep the potting soil slightly dry, remove the plant from the pot, shake off the medium on top, wash it clean with water, and dry it. When dividing, 3-5 seedlings can be used as one plant. After dividing, you can use 0.1% potassium permanganate or carbendazim to disinfect the roots, then dry them before planting separately.
2. Orchids have high requirements for potting materials. Ordinary soil is not easy to grow them well. Prepare the potting materials in advance when repotting. You can use more decomposed pine needles, bark, peanut shells, and other media, which should ensure good water permeability and air permeability, as well as rich nutrients for plant growth.
II. Watering Requirements
When the weather warms up, the plants begin to grow and develop, and the demand for water also increases. You can appropriately increase the amount of watering at this time. Especially when the potting material has good water permeability and air permeability, the potting soil dries faster, and it is necessary to observe the moisture level of the potting soil and supplement water in time. When watering orchids, make sure to water thoroughly until water flows out from the bottom of the pot. As long as there is no waterlogging in the pot, you generally don't have to worry about root rot caused by excessive watering.

With the rise of temperature, the weather will also become dry. It is also necessary to spray the orchid plants frequently to increase the humidity of the environment, which is beneficial for plant growth.
III. Supplementing Nutrition
In order to ensure that the plants have sufficient nutrients to maintain growth and development, it is necessary to supplement some nutrients frequently during the period of vigorous growth in spring. Generally, fertilize once every half a month with a dilute fertilizer. For plants that are about to bloom, you can appropriately add some phosphorus and potassium fertilizers to promote flowering.
Ordinarily, you can also ferment some organic fertilizers such as sheep manure and soybean cakes and apply some to the potting soil. This can not only improve the soil but also supplement nutrients, promoting vigorous plant growth.
IV. Pay Attention to Sun Protection
Orchids also need sunlight during the spring growing period. You can give them some scattered light to perform photosynthesis, which will make the plants grow stronger and more upright. However, do not place them directly under strong sunlight, especially in the summer when the intensity of sunlight is high, as it can easily cause the plants to wither and droop.
In the process of caring for orchids in spring, it is also necessary to prevent frost, as the temperature in early spring is unstable with large temperature differences between day and night. It is recommended not to move the orchids outside too early to avoid sudden temperature drops that could freeze the plants.
This article shares the specific introduction of how to cultivate spring orchids and the cultivation methods and precautions of spring orchids, hoping to bring some knowledge of flowers to green plant enthusiasts.
