About soil condition, there are many abelia varieties that prefer well-drained soil; however, there are a few that are tolerant of boggy conditions, such as 'Red Tinkerbell' and 'Super Star'. These latter varieties are perfect for planting near water features or in areas of the garden that tend to be wet.
Not too different with other plants, the amount of sun an abelia plant needs depends on the variety. Some can handle full sun while others require partial shade. The key is to know your plant and check the tag or ask the nursery before purchasing.
The temperature condition that is best for abelia varieties is between 60 and 75 degrees Fahrenheit. They can withstand colder temperatures down to about 50 degrees, but anything below that can damage or kill them. Because they are native to warm climates, they prefer full sun but can also tolerate partial shade. They are drought-tolerant once established, but will flower and foliage more profusely with regular watering.
Ideal humidity condition for this plant is between 40% and 60%. The plant will suffer if the humidity is below 30% or above 70%. If the humidity is too low, the leaves will turn brown and drop off. If the humidity is too high, the plant will become susceptible to fungal diseases.
About fertilizer, this kind of plant doesn't require a lot of nutrients. It's best to use a slow-release fertilizer or a water-soluble fertilizer monthly during the growing season. Root system, Abelia has a fibrous root system with woody, spreading roots that are close to the surface.
Pruning is an important part of caring for abelia varieties. While it is not necessary to prune every year, it should be done every few years to remove any dead or damaged branches. It is also important to prune back any branches that are growing out of bounds.
Propagation is best done in late summer or early fall by taking stem cuttings from new growth. Fill a planting tray or flat with a moistened soilless mix and make a hole in the center of each cell with a pencil. To encourage root growth, remove the bottom leaves from the cutting and dip the leafless portion of the stem in rooting hormone powder. Firm the mix around the stem, being careful not to damage the cutting, and water well. Place the tray or flat in a bright location out of direct sunlight and mist daily to keep the mix moist but not soggy. New roots should form within four to six weeks. Once the roots are well-established, transplant the cuttings to 4-inch pots filled with a well-drained potting soil.
Usually, the plant growth rate is rather slow, especially during the first year after planting. However, once they are established, they will grow more rapidly. Some of the more popular varieties include 'Edward Goucher', 'Kaleidoscope', and 'Sherwood Compact'.
Common problems for this kind of plant are powdery mildew, scale, and thrips. These problems are usually seen in the late summer or early fall. The best way to control these problems is to remove the affected leaves and try to keep the plant as dry as possible.
