About soil condition, the pearl bush prefers well-drained soils, but it is tolerant of a range of soil types and conditions. It is not particular about pH and will grow in acidic to slightly alkaline soils. The plant is also tolerant of salt and can be grown in coastal areas.
Similar to other flowering plants, the pearl bush requires sunlight in order to grow and produce flowers. The amount of sunlight required will depend on the variety of pearl bush. Some varieties can tolerate partial shade, while others need full sun. If you are unsure how much sun your particular variety needs, you can ask your local nursery or gardening center.
The temperature condition in the pearl bush is warm. The average temperature is about 28 degrees Celsius. The bush can tolerate a wide range of temperatures, from about 18 degrees Celsius to about 38 degrees Celsius. It can also tolerate occasional frosts down to about -5 degrees Celsius.
Ideal humidity condition for this plant is 50-60%. If the humidity level drops below 50%, the leaves will start to turn brown and crispy. If the humidity level goes above 60%, the leaves will start to turn yellow.
Regarding fertilizer, this kind of plant prefers lower doses of fertilizer compared to other plants. Fertilize your pearl bush every two weeks during its growing season with a half-strength solution of an all-purpose fertilizer. It's especially important not to overdo it on the nitrogen, which will produce lots of foliage at the expense of flowers. If you see the plant's leaves turning yellow, that's a sign that it's getting too much nitrogen.
Pruning pearl bush is essential to keeping the plant healthy and vigorous. The best time to prune is in late winter or early spring, before new growth begins. Pearl bush can be pruned quite hard if necessary, as it is a very resilient plant. When pruning, be sure to remove any dead, diseased, or damaged branches, as well as any crossing or rubbing branches. Cut back remaining branches to the desired shape or size, making sure to make clean, sharp cuts.
Propagation of pearl bush is done through stem cuttings taken from young, actively growing plants in late spring or early summer. The cuttings should be 4-6 inches long and taken from the tips of the stems. Place the cuttings in a rooting medium such as perlite, vermiculite, or sand. Keep the rooting medium moist but not wet and in a location with bright, indirect light. Rooting should occur in 4-6 weeks. Once rooted, pot the cuttings into individual pots and grow on under bright, indirect light.
Usually, the plant growth rate is determined by the availability of water. In areas with high rainfall, the plant will grow more quickly. In arid regions, growth will be more limited. Fertilizer can also impact growth rates, with more nutrients resulting in more rapid plant growth.
Common problems for this kind of plant are caterpillars, aphids, and spider mites. These pests are often controlled with insecticidal soap, neem oil, or horticultural oil. caterpillars can also be controlled with Bacillus thuringiensis.
