They can tolerate some periods of warmer temperatures, but they will not do well if the temperature consistently stays above 80 degrees Fahrenheit. If the temperature does get too hot, the leaves of the plant will start to wilt and the plant will become stressed.
Ideal humidity condition for this plant is 50% or below. anything above that and the plant will start to suffer. the leaves will begin to droop and the plant will start to wilt. if the humidity gets too high, the plant will start to experience leaf loss and eventually die.
For the fertilizer, this family of plant prefers one that is low in nitrogen. The ideal range for the nitrogen is between 1 and 3 percent. For the phosphorus, the range should be between 1 and 2 percent, and for the potassium, the range should be between 2 and 4 percent.

Another variety, Snowball Bush (Ceanothus velutinus), is known for its round, white flowers. It grows to about 10 feet in height.
Usually, the plant growth rate is relatively slow. However, some varieties may grow at a faster rate if they are grown in ideal conditions. The 'Marie Simon' ceanothus is one of the fastest-growing varieties, able to grow up to 2 feet per year. When grown in ideal conditions, this plant can reach a height of 6-8 feet in just 3-4 years.
Common problems for this kind of plant include leaf spot, powdery mildew, root rot, and stem canker. These problems are typically caused by too much moisture or poorly drained soils. To avoid these problems, make sure to plant your ceanothus in well-drained soil and water it only when the soil is dry.
