Do you need to turn the pot over in spring?
As a star flower in winter and spring, Crabclaw orchid is popular among gardening enthusiasts for its bright lantern-shaped flowers. As the temperature rises, many flower lovers begin to pay attention to the key points of spring maintenance-do they need to turn the pots? Can the flowering period continue? This article will provide you with a detailed analysis from the perspective of scientific conservation. Analysis of the necessity of changing pots in spring and the best opportunity to change pots is judged. When the roots of Crabclaw are exposed, the pot soil is hardened, and new air roots are born (as shown in the figure), it is the signal to change pots. It is recommended that the average daily temperature be stabilized above 15℃ from March to April, when the plants are in a semi-dormant state and the damage caused by changing pots will be minimal. The key steps of the pot changing operation adopt the "three cuts and three elimination" method: cut off 1/3 of the old roots, cut off dry stems, and cut off dense branches; disinfect the roots with carbendazim solution, disinfect the new pot, and disinfect the soil matrix. Pay special attention to retaining the core soil of the core part of the original soil ball, which can significantly shorten the serving time. Maintenance techniques for extending flowering period in spring, light and temperature control maintain the optimal growth temperature of 15-25 ° C, and adopt the principles of "three avoidance and three guarantees": avoid direct strong light, avoid direct cold wind blowing, and avoid excessive temperature differences between day and night; keep sufficient scattered light and maintain air circulation and environmental humidity of about 60%. Fine water and fertilizer management Apply phosphorus and potassium fertilizer (diluted 1000 times) every week during the flower bud period, combined with foliar spraying of boron fertilizer. Use the "see the dry, see the wet" watering method, and wait until 2 cm of the soil surface of the basin is dry before pouring water to avoid falling flowers and buds caused by accumulated water. The re-flowering promotion plan of Crabclaw orchid can extend the flowering period through temperature difference stimulation: it maintains 20-25℃ during the day and drops to 12-15℃ at night. Cut off the remaining flowers in time after the flowers fade, retain 3-4 nodes of the stem, and combine the application of nitrogen, phosphorus and potassium balanced fertilizers, so that some varieties can bloom twice in late spring.
Mastering scientific pot changing methods and flowering control techniques can not only help Crabclaw orchid spend spring safely, but also achieve the ornamental effect of blooming in multiple seasons throughout the year. It is recommended to conduct root inspection every spring and flexibly adjust the maintenance plan based on plant growth so that this "Christmas cactus" will continue to bloom.
