About soil condition, cercis chinensis grow in a variety of soils, from sandy to heavy clay, as long as it is well-drained. It grows best in soils with a high organic content. The soil should be moist but not wet, and it should be well-drained.
Like the other trees, the cercis chinensis needs sun to grow. It should be planted in an area that gets full sun to partial shade. It can tolerate partial shade, but it will not produce as many flowers. The tree does best in well-drained soil.
The temperature condition that is most favorable for the growth of the Chinese redbud (Cercis chinensis) is a temperature that is neither too hot nor too cold. The ideal temperature range for the Chinese redbud is between 60 and 70 degrees Fahrenheit. However, the Chinese redbud can also tolerate temperatures as low as 40 degrees Fahrenheit and as high as 80 degrees Fahrenheit. If the temperature gets too cold, the Chinese redbud will stop growing and if the temperature gets too hot, the Chinese redbud will start to wilt.
Ideal humidity condition for this plant is around 40% to 50%. The plant can tolerate lower humidity but the leaves will suffer and may drop. Higher humidity will also cause the leaves to suffer and drop.
Mentioning fertilizer, usually the plant nutrients including nitrogen, phosphorus and potassium are applied to promote growth. For Cercis chinensis, the roots are shallow and widely spread, so a light top dressing of fertilizer is all that is needed. The roots are also very sensitive to disturbance, so it is important to be careful when working around them.
Pruning is an important part of keeping your cercis chinensis healthy and looking its best. Depending on the size and shape of your plant, you may need to prune it every few months to keep it from getting too large or wild-looking. To prune your cercis chinensis, start by removing any dead or dying branches. Then, trim back any branches that are growing out of control. Finally, cut back any branches that are crossing over or rubbing against other branches.
Propagation of the cercis chinensis is best done through softwood cuttings taken from new growth in the spring. The cuttings should be 4-6 inches long and taken from the tips of the branches. They should be placed in a potting mix that is moist but not wet and kept in a warm, sunny location. Once they have rooted, they can be transplanted into their permanent location.
Usually, the plant growth rate data is for young trees in nurseries. In one study, the average growth rate for cercis chinensis was 26.4 cm per year for the first three years (Fang et al. 2002). However, the average growth rate slowed to 10.2 cm per year for the next three years and then to 5.1 cm per year after six years (Fang et al. 2002). The maximum growth rate recorded in this study was 39.6 cm per year for a three-year-old tree (Fang et al. 2002).
Common problems for this kind of plant are that the leaves may turn yellow and drop off, the branches may die back, and the plant may fail to flower or fruit. These problems are usually caused by incorrect watering, over-fertilizing, or pests and diseases.
