How to care for newly bought cold orchids

1. How to deal with cold orchids after buying them

You can spread out the newly bought orchid to dry in the air and check whether there is any root rot. If there is, you need to cut it off with scissors. Then soak the roots of the plant in 5% potassium permanganate solution for half an hour to sterilize the roots of the plant. After soaking, place it in a ventilated place to dry, and finally choose suitable potting soil for potting.

2. Specific breeding methods

1. Soil: For growing cold orchids, you can choose relatively fertile soil. When planting, you can choose a high-footed pot. Use coarse-grained bricks or foam plastic blocks to lay the bottom at one-third of the pot. In the middle, mix red soil brick sand to one-third of the pot. On the top, mix rice-sized sand with a small amount of humus.

2. Watering: It likes moisture and avoids dryness. It is not suitable to water it too much when you just buy it. You can water it every 3-5 days and spray water on the leaves once a day to ensure the moisture of the soil. It should be noted that each time you water, you must water thoroughly, but do not allow water to accumulate in the soil, otherwise the roots of the plant are likely to rot.

3. Temperature: It likes a relatively warm environment. When you first buy it, you can place it in an environment with a temperature of around 24°C for maintenance. If the temperature exceeds 35℃ in summer, the plant will grow poorly, so shading and cooling are needed. Under normal circumstances, its optimal growth temperature is 15℃-30℃. When the temperature is below 5℃ in winter, it will affect its growth and it will be in a dormant state. Therefore, certain insulation measures must be taken in winter so that it can survive the winter safely.

4. Light: It likes shade and avoids direct sunlight. Excessive light can easily cause sunburn of the leaves and cause sunburn. When you first buy it, you can put it in a semi-shaded environment and give it appropriate scattered light. However, it should not be overly shaded or kept indoors for a long time, as this will easily cause the plant to grow poorly and be difficult to bloom. Under normal circumstances, as long as the leaves of the plant are not burned, it can be exposed to more sunlight.

5. Fertilization: It does not require much fertilizer. No fertilizer is needed during the acclimatization period. Under normal circumstances, fertilizer can be applied 2-3 times a month, alternating between using potassium dihydrogen phosphate, Lanjunwang, etc. as foliar fertilizers. During the growth period of new sprouts, you can add some urea in moderation, and spray high-potassium fertilizer two to three times when the new seedlings mature. We can apply thin organic fertilizer once a month in April-June and September-October, and avoid applying concentrated fertilizer to avoid fertilizer damage.
