The tree produces lovely pinkish-white flowers that bloom in the springtime. prunus kanzan is a popular plant in cultivation and is often used as an accent plant in gardens.

About soil condition, the Prunus kanzan is best in well-drained, loamy soil with a slightly acidic to neutral pH. It tolerates a wide range of soils but performs best in soils that are deep, moist, and not overly rich.
Not too different with other plum trees, the prunus kanzan requires full sun in order to produce the most fruit. It is possible to grow this tree in partial sun, but it may not produce as much fruit. In addition, the tree will need to be watered regularly in order to prevent the roots from getting too dry.
The temperature condition of Prunus kanzan is optimal for growth between 60-70 degrees Fahrenheit. Prunus kanzan will go into dormancy below 60 degrees Fahrenheit and experience a loss in vigor and productivity. Above 70 degrees Fahrenheit, Prunus kanzan will experience an increase in respiration rate and a decrease in photosynthesis.
Ideal humidity condition for this plant is 40-50%. If the humidity is any lower, the plant will start to suffer and may eventually die. If the humidity is too high, the plant will become susceptible to pests and diseases.
Discussing fertilizer, usually the plant needs more nitrogen when it is actively growing in the spring. A general rule of thumb is to use 1/4 the recommended amount on the fertilizer package. However, it is best to have your soil tested to see what nutrients it is lacking so you can provide what the plant needs specifically. As for the roots, they grow best in loose, well-drained soil. If the soil is too compacted, the roots will have trouble growing and the plant will be stunted.
Pruning your Prunus kanzan plant is important to maintaining its shape and preventing it from getting too large. You should prune in early spring, before new growth starts. Cut back any dead or damaged branches first. Then, cut back any branches that are growing too long or out of shape. Finally, cut back any branches that are crossing or rubbing against each other.
Propagation of Prunus kanzan is typically done through rooting hardwood cuttings taken from the previous season's growth. The cuttings should be taken from healthy, vigorously growing branches that are about 2-4 inches in diameter. Cuttings should be taken from the upper portion of the branch and should be around 18 inches long. The bottom end of the cutting should be cut at a 45-degree angle, and the top end should be cut at a sharp angle. The cuttings should then be placed in a moist media such as perlite, vermiculite, or sand. They should be placed in a propagator or covered with a clear plastic bag to maintain high humidity. Cuttings should be kept at a temperature of 70-75 degrees Fahrenheit.
Usually, the plant growth rate is about 1 meter per year. The average lifespan of a prunus kanzan is about 20 to 30 years, with some individual trees living for much longer. The oldest known prunus kanzan tree is about 400 years old.
Common problems for this kind of plant are canker, powdery mildew, black knot, and leaf spot. Canker is a fungal infection that can kill parts of the tree. Powdery mildew is a white powdery fungus that can cause leaves to drop. Black knot is a black fungus that can kill the tree. Leaf spot is a brown or black fungus that can cause leaves to drop.
