About soil condition, it prefers rich, well-drained soils but once established, it is quite tolerant of less than ideal conditions such as poor soils, drought, and salt. In fact, it is often used in landscaping to help stabilize problem areas.
Like the other magnolia trees, the Japanese magnolia (Magnolia x soulangiana) requires full sun to partial shade to thrive. It should be planted in an area that receives at least six hours of direct sunlight each day. The tree will also do well in dappled shade, or light that filters through the branches of trees. too much shade will make the Japanese magnolia's leaves turn yellow and may even cause the tree to drop its flowers.
The temperature condition of the Japanese magnolia is very important for the growth and flowering of the plant. The plant prefers a temperature range of 15 to 20 degrees Celsius for optimal growth. However, the plant can tolerate a wide range of temperatures, from -10 to 35 degrees Celsius. The plant will not flower if the temperature is below 10 degrees Celsius.
Ideal humidity condition for this plant is 60-70%. If the humidity is too low, the leaves will dry out and the buds will fall off. If the humidity is too high, the leaves will yellow and the plant will be more susceptible to diseases.
Mentioning fertilizer, this kind of plant need average watering, in order to maintain a good control of the watering, we recommend using a fertilizer that has a high content of phosphorus and nitrogen. Also, the ideal way to fertilize japanese magnolia is to use a fertilizer that has a low content of potassium.
Pruning is an important part of caring for a Japanese magnolia. Pruning not only helps to keep the tree healthy, but also can help to shape it and keep it looking its best. When pruning, be sure to remove any dead or diseased branches, as well as any branches that are rubbing against each other. It is also a good idea to prune back any branches that are growing too close to power lines or buildings.
Propagation of the Japanese magnolia is typically done by taking softwood or hardwood cuttings from the mother plant. The cuttings should be taken from new growth that is about 6-8 inches long. The cuttings should be taken from the middle of the stem and have at least 2-3 leaves on them. The bottom leaves should be removed and the cutting should be placed in a pot with moistened potting mix. The pot should be placed in a warm location and the cuttings should be monitored for new growth. Once the cuttings have rooted, they can be transplanted into individual pots.
Usually, the plant growth rate is about 1 to 2 feet per year. In ideal conditions, some magnolias can grow up to 3 feet per year. Magnolias that are grown in poor conditions may have a growth rate of only 1/2 foot per year.
Common problems for this kind of plant are root rot, powdery mildew, and scale. Root rot is caused by too much water and can be fatal to the plant. Powdery mildew is a white powder that covers the leaves and can cause them to turn yellow and fall off. Scale is a small insect that sucks the sap out of the plant and can cause the leaves to turn yellow and fall off.
