About soil condition, Deutzia chardonnay pearls prefer well-drained soil that is slightly acidic. You can add some organic matter to the soil to help with drainage. Deutzia chardonnay pearls are tolerant of clay soils.
So, like the other Deutzia species, the Deutzia chardonnay pearls require full sun to partial sun. The amount of sun required depends on the climate. If you live in an area with hot summers, then your Deutzia chardonnay pearls will need some afternoon shade. If you live in a cooler climate, then they will need full sun to partial sun.
The temperature condition is perfect for the Deutzia Chardonnay Pearls. They need a cool environment to thrive and the temperature condition is just right. They are also very sensitive to changes in temperature, so the condition must be monitored closely.
Ideal humidity condition for this plant is 60-70%. If the air is too dry, the leaves will begin to drop and the plant will become less blooming. If the air is too humid, the plant is susceptible to diseases such as powdery mildew.
Mentioning fertilizer, usually the plant food has three numbers such as 10-10-10 or 16-4-8. These numbers are the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. The first number is always nitrogen. It is the element that helps the most with vegetative growth such as leaf growth. The second number is phosphorus and it helps the plant produce fruit, flowers, and roots. The last number is potassium and it helps the plant resist disease and helps with overall plant health.
Pruning deutzia should be done in late winter or early spring, before new growth begins. Cut back the previous year's growth by about one-third to promote branching. Deutzia can also be pruned to shape as needed.
Propagation of Deutzia chardonnay pearls can be done through stem cuttings. Cuttings should be taken from new growth that is about 6-8 inches long. Cuttings should be taken from the bottom of the stem, and each cutting should have 2-3 sets of leaves. Cuttings should be placed in moistened potting mix, and kept at a temperature of about 68 degrees Fahrenheit. Cuttings should root within 4-6 weeks.
Usually, the plant growth rate is considered to be moderate. However, they can grow rapidly if they are given the right conditions. They prefer full sun but can tolerate some shade. The soil should be well-drained and fertile. They are generally quite drought tolerant once they are established.
Common problems for this kind of plant are that the leaves may curl or discolor and the stems may break. These problems are typically caused by too much sun, too little water, or too much fertilizer. If the leaves curl, try shading the plant from direct sunlight. If the leaves discolor, try watering the plant more frequently. If the stems break, try using a staking material to support the plant.
