Begonia is a deciduous shrub of the genus Papaya in the family Rosaceae, and is an important early spring flowering shrub in landscaping. Its flowering is early, the flowers and leaves are released together, the flowers are open when the green leaves first unfold, and the leaf color is dark green and shiny. The flowers resemble begonia flowers, almost attached to the branches, and the peduncle is extremely short, hence the name. Xiaobian summarized the experience of many parties and sorted out a set of cultivation management techniques for sticking stemmed begonias, which are now introduced as follows for your reference.
First, the choice of planting site
Begonia is native to Shaanxi, Gansu, Sichuan, Yunnan and other places in China, and prefers warmth and fears cold. Therefore, it is best to choose a leeward and sunny place to cultivate begonias in North China. Sticking stemmed begonias are afraid of standing water, grow poorly in low-lying places, and are prone to yellow leaves and fallen leaves, so sticky begonias should be planted in places with higher terrain, and should also be planted in the lawn to properly raise the terrain and avoid flood irrigation; Begonia is not strict on the soil requirements, and can grow normally in loam soil and light clay soil, but it is best grown in fertile and permeable sandy loam soil.
Second, water and fertilizer management
Although the sticker begonia is afraid of standing water, it still prefers a humid environment, so it should not be watered less or not because it is afraid of standing water. First, the annual antifreeze water and rejuvenation water must be indispensable, the antifreeze water must be watered before mid-November to early December, the rejuvenating water must be watered in early March, and it must be watered thoroughly, in addition, it is also very necessary to water it again in the middle of April after flowering. The rest of the time should be based on the soil moisture to grasp the number of watering and watering, generally speaking, in the summer rainy season should be controlled watering, such as too much rain should also pay attention to drainage. It should also be noted that watering should be controlled after the autumn to prevent autumn hair, so that the new branches will suffer frost damage during the winter.
Begonia stickers like fertilizer, generally can be applied three times a year fertilizer, one is the spring post-flower fertilizer, mainly nitrogen fertilizer, can be applied at the same time to some decomposed fermentation of cattle and horse manure or chicken manure; the second is in July and August, during the differentiation of its flower buds, apply some phosphorus and potassium compound fertilizer, at this time fertilization, can promote flower bud differentiation, increase the number of flowers; The third is to apply some base fertilizer in combination with watering winter before entering winter, which not only has long-lasting fertility but also can effectively enhance the tree potential and improve the flowering quality in the coming year.
Pruning and reproduction
In Northern China, the tree shape of Begonia spp.-stalked begonias is commonly shrub type. The ideal shrub type should maintain a state of inner high and outer low, and the inside and outer are dense. The following two points should also be noted when trimming. First, it is necessary to remove over-dense branches, diseased branches, and intersecting branches when pruning. Second, pay attention to the renewal of flowering branches.
The propagation of begonias can be carried out by cuttings and splitting, but cuttings are the most commonly used, and a large number of seedlings can be obtained at one time. The most commonly used cuttings are hard branch cuttings. Hard branch cuttings to early spring is better, select an annual robust branch, thickness between 0.5 and 1 cm, cut into about 12 cm long cuttings, tidy up the garden and after disinfection, carry out cuttings, plant row spacing of 20×30 cm, after the cuttings are immediately watered once permeable, and coated insulation, after which the soil in the film should be kept moist for a long time, and often open the film for ventilation, about 40 days can take root, after autumn can be transplanted.
Fourth, pest control
Sticker begonia rust is a common disease and multiple diseases of begonia, when the disease is serious, it can lead to plant death, if there is a occurrence, it can be sprayed with 50% debacterial special wettable granules 800 times liquid, sprayed every 10 days, continuous spray 3 to 4 times can effectively control the disease. It should also be noted that tree species such as juniper cypress and cypress are the forwarders of begonia rust, so they should be avoided adjacent to these trees when planting. The common insect pests of begonias are mesozoites, aphids, red spiders, yellow thorn moths, etc., in the daily maintenance should strengthen water and fertilizer management, enhance ventilation and light transmission, if there is a problem, aphids can be used to kill the shell insects, kill aphids with aphids, and spray yellow thorn moths with predators.
