Detailed Explanation of the Latest Cultivation and Management Key Points for Redbud
Redbud flowers have a wide distribution range in our country, mainly concentrated in Jiangsu, Beijing, Shandong and other provinces. The flowers of the redbud are very brightly colored with high glossiness and high ornamental value. In addition, the bark, wood, flowers and fruits of the redbud can all be used as medicine, therefore there is also a very large area of artificial cultivation. However, when planting, we must do a good job in field management to ensure the healthy growth of the redbud. So below, the editor will introduce the field management techniques for redbud to everyone!
1. Water Management
Water is very important for the growth of redbud. After planting, water immediately. Especially in the early stage of planting, water at least three times in the first seven days to meet the water requirements of the redbud. When watering, control the watering frequency and amount according to weather changes. For example, in summer, water in time to lower the temperature, but do not overwater, and pay attention to drainage after rain. If the temperature is not high in autumn, control the amount of watering to prevent autumn decline, then water thoroughly with antifreeze water to enhance the cold resistance of the redbud. In the spring of the second year, water in time during the green-up period. From April to October each year, except for controlling watering according to precipitation in July and August, water once a month.
2. Proper Topdressing
The growth of redbud has a very large demand for nutrients. Under conditions of sufficient nutrients, the healthy growth of the redbud can be ensured, the amount of branches and leaves can be increased, and the glossiness of the flowers can be enhanced. Otherwise, the redbud will have few branches and leaves, and the flowers will be dull and lackluster. Therefore, before planting, apply sufficient base fertilizer. The base fertilizer is mainly fully decomposed farmyard manure, and it should be thoroughly mixed with the soil to prevent excessive heat release from burning the roots. After normal growth, properly apply nitrogen fertilizer after flowering each year to enhance the growth vigor of the redbud, then apply phosphorus and potassium fertilizer in early autumn to promote flower bud differentiation. Also, when watering with antifreeze water in early winter, apply farmyard manure once, then properly spray foliar fertilizer according to the plant's growth vigor, so as to fully meet the nutrients needed for the growth of the redbud.
3. Shaping and Pruning
Under normal growth conditions, the redbud plant has lush branches and leaves. If it is not pruned in time, the branches will grow in a complicated and tangled way, reducing air and light permeability and hindering the growth of the redbud. Especially when the redbud is used for ornamental purposes in various gardens, pruning work should be done well during its young tree stage to promote the formation of a good plant shape and enhance ornamental value. After transplanting, properly shorten the branches to promote the growth of branches, increase the area for nutrient absorption, and ensure sufficient nutrient accumulation. Then in the spring of the second year, heavily shorten the branches to promote the sprouting of new branches, and retain about three strong-growing branches, cutting off excess branches. Then promptly remove excess suckers, properly pinch the tips, and promote secondary branching.

The redbud has a relatively large demand for light, so when planting, we should pay attention to meeting the light requirements of the redbud, enhancing its photosynthetic capacity, increasing nutrient accumulation, and increasing its ornamental value. However, be careful to avoid prolonged direct sunlight, otherwise it is prone to adverse phenomena such as high-temperature heat damage and scorched leaves. Therefore, while ensuring light, we should also provide appropriate shade. Finally, in winter, do a good job in clearing the garden. Pathogens overwinter in diseased plant residues, soil, and weeds, and harm the redbud in the spring of the second year, causing diseases and pests. Winter garden clearing can effectively reduce the pathogen base and lower the incidence of disease.
The above is a brief introduction to the key points of redbud cultivation and management. When pruning redbud trees, pay attention to doing a good job in renewing the flowering branches of the redbud. Generally, flowering branches more than 5 years old will greatly reduce their flowering amount, and the flowering position moves upward, seriously reducing ornamental value, so they should be renewed in time. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
