How to raise and water the crab claw orchid in summer and winter

Crab claw orchid is actually a tropical rain forest cactus plant native to Brazil. They are originally plants that grow on trees or rocks. They like warm and humid environments all year round. The cultivation location is generally high in humidity. In summer, the temperature is too high. Crab claw orchid is easy to cause problems.

1. When is the best time to transplant crab claw orchid?

Sunflower is most suitable for transplanting after flowering, avoid transplanting in winter, and do not choose to transplant in autumn. Their flowering period is flowering in winter and spring. They can be transplanted after warm spring. They grow slowly and do not need frequent transplanting. Generally, they need to change pots every 3~5 years. If your crab claw orchid does not bloom, you can choose to change pots at the end of winter.

The best pot change is to use red pottery pots, the size of the container can not be too large, the size is just right, the container must have a larger drainage hole to avoid soil ponding.

Red pottery pots also have good air permeability, which can help the root system of crab claw orchid grow better and avoid root rot.

2. Selection of potted soil

The cultivation of crab claw orchid must use loose and well drained sandy soil, which can be mixed with pearlite or coarse sand with some peat soil, or can be replaced by compost soil, which can be mixed with 1/2 peat soil, 1/4 pearlite and 1/4 coarse sand. Such soil is a good choice for cultivation of crab claw orchid.

3. Pay attention to changing pots and transplanting

Do not water before transplanting, do not water 1~2 weeks before transplanting, let the soil slightly dry, this can prevent root rot, planting with new flower pots and soil, old soil must be sterilized before use, the bottom of the pot can be paved with a layer of granular stones or broken tiles, after which the crab claw orchid can be transplanted.

Grasp the root base of the crab claw orchid and carefully remove it from the old pot. The edge of the pot can be poked slightly to help the crab claw orchid pull out better. Then carefully remove the old soil without damaging the root system.

When planting, you can hold the rhizome with one hand, add soil later, and press it slightly after planting.

After planting, do not water the crab claw orchid first. Put it in a ventilated and shaded place. It can be watered after 5~7 days. Because the damaged root system cannot absorb water, watering immediately can easily cause root disease.

4, watering precautions:

Most cacti are very drought-tolerant, high-temperature resistant, and crab claw orchid is exactly the opposite, it is a tropical rainforest plant, like the perennial humid environment, like higher air humidity, although not frequent watering, but the growth period also to keep the soil moist.

The most important thing to conserve crab claw orchid is summer. When the temperature is high in summer, crab claw orchid will fall into dormancy. It is easy to rot roots with too much water. It is necessary to control watering properly. After the pot soil is dry, it will be watered thoroughly.

In summer, we should also maintain a good ventilation environment, avoid keeping it in a sultry environment, and do not place it directly against the window in summer, otherwise it is easy to burn the leaves.

5. Dry and wet conditions of soil

In addition to the need to properly control watering during summer and flowering, the soil should be kept properly moist in spring and autumn. When the soil is dry about 3 cm below the soil surface, it needs to be replenished with water. Don't let the soil dry completely, otherwise it will cause the plants to wither. The frequency of watering also varies with ambient temperature, light and relative humidity.

6. Location of maintenance

The environment for the conservation of crab claws is very critical. The location of conservation should be ventilated, with good air humidity, and it is best to have 4 to 6 hours of scattered light every day.

In order to promote flowering, it should be completely dark at night in autumn, and it should not be kept in a position where there are lights during the day and night. In autumn, it should be kept completely dark for about 12 hours at night, and the temperature should be kept between 12 and 18 degrees, so as to promote flowering.

7. Fertilization

In addition to proper watering and suitable environment, but also regularly supplement fertilizer, generally in the spring and autumn season supplement fertilizer, can be properly supplemented after flowering potassium dihydrogen phosphate, other seasons as long as the temperature is not too high, can give a thin average fertilizer for 2 to 3 weeks, autumn when breeding buds and then 1 to 2 weeks supplement potassium dihydrogen phosphate solution, can be very good to promote flowering.
