Does crabapple have leaves in winter?
As a representative of traditional famous flowers in China, the growth status of crabapple in winter often attracts the attention of gardening enthusiasts. Its leaf changes and flowering characteristics are not only related to variety differences, but also reflect the intelligent adaptation of plants to seasonal changes. Begonia leaves in winter, natural leaves mechanism Begonia is a typical deciduous shrub. When the temperature drops below 10℃ in late October, its leaves begin to synthesize abscisic acid. The base of the petiole forms a detached structure, the chlorophyll gradually decomposes, and the defoliation process is basically completed by the end of November. Special varieties show that cold-resistant varieties such as Begonia can retain a small number of dead leaves until mid-December, but the new leaves still strictly follow the seasonal rules. Evergreen crabapple mostly refers to special varieties such as tied-stem crabapple, which needs to be distinguished from regular crabapple. Analysis of Winter Blooming Characteristics of Four Seasons Begonia The characteristics of Four Seasons Begonia and Four Seasons Begonia can achieve winter flowering in a greenhouse environment above 15 ° C. Artificial supplementary light can extend the light to 14 hours/day, and phosphorus and potassium fertilizers can promote flower bud differentiation. The natural flowering period is compared with the traditional Xifu crabapple bloom intensively from April to May, and the Yangtze River Basin blooms 10-15 days earlier than in the north. Plants that bloom in winter require special temperature control, and it is difficult to achieve natural winter flowers when planted in the open. Low temperature environment maintenance system The planting plant in the temperature control plan adopts the root-neck soil method, and a 30-cm-high mound is piled to protect the root system. It is recommended to maintain potted plants above 8℃, and pay attention to noon ventilation when using double-layer temperature-controlled sheds. Water management techniques During the dormant period, the principle of "see dry, see wet" is implemented, and the soil water content is maintained at 30%-40%. The northern heating environment is coordinated with humidifiers to maintain 40% air humidity to prevent branches from drying out. Light replenishment strategy Ensure direct light for 4 hours per day before and after the winter solstice. Use full-spectrum plant fill light in rainy and snowy weather, and illuminate it for 6 hours/day from a distance of 50cm from the crown width to effectively prevent excessive growth.
By understanding the physiological characteristics of crabapple in winter, targeted protective measures can be taken. Select appropriate varieties and cooperate with scientific maintenance, and you can appreciate the unique charm of crabapple even in the cold season.
