It is recommended to grow Scaevola kilaueae O. Deg. in well-draining soil with a pH range of 6.5 to 7.5. The soil should be rich in organic matter and have good drainage to avoid waterlogging. The plant prefers full sun to partial shade and can tolerate salty conditions.
Propagation of Scaevola kilaueae O. Deg. can be done through seed or stem cuttings. Seed germination can take up to two weeks, and the seedlings should be transplanted when they have developed a few leaves. Stem cuttings taken from healthy plants can be rooted in a pot with good quality potting soil.
Watering needs of Scaevola kilaueae O. Deg.
Scaevola kilaueae O. Deg. requires moderate watering with a well-draining soil. Overwatering or waterlogging can lead to root rot and eventually kill the plant. The plant should be watered when the soil is dry to the touch. During the summer months, the plant may require more frequent watering. It is recommended to water the plant at the base to prevent the foliage from getting wet and avoid fungal diseases.
Fertilization of Scaevola kilaueae O. Deg.
Scaevola kilaueae O. Deg. benefits from regular fertilization with a balanced fertilizer. The plant should be fertilized during the growing season, which is usually from spring to fall. Fertilization should be reduced or stopped during winter as the plant goes into dormancy. It is recommended to use a slow-release fertilizer or liquid fertilizer diluted to half strength to prevent overfeeding and burning the plant.
Pruning of Scaevola kilaueae O. Deg.
Scaevola kilaueae O. Deg. does not require much pruning, but it benefits from occasional deadheading. Deadheading involves removing the spent flowers to promote new growth and prolong blooming. Pruning should be done during the dormant stage in winter to remove any dead or damaged branches. It is recommended to use a clean and sharp tool to prevent damaging the plant.
Propagation of Scaevola kilaueae O. Deg.
Scaevola kilaueae O. Deg., also known as the Kilauea Beach Naupaka or Naupaka kahakai, is a coastal plant native to Hawaii. Propagation of this plant can be done through several methods:
Seed Propagation
The easiest and most common method of propagating Scaevola kilaueae is through seeds. Seeds should be collected from ripe fruits and sown in a well-draining soil mix. Keep the soil moist and warm, around 70-80°F (21-27°C), until the seeds germinate. Germination can take between two to four weeks.
Cuttings Propagation
Propagation of Scaevola kilaueae can also be done through cuttings. Take stem cuttings of around 4-5 inches (10-12 cm) that are not flowering. Dip the cut end in rooting hormone and plant in a well-draining soil mix. Keep the soil moist and warm until the cuttings establish roots. This can take up to four weeks.
Division Propagation
Scaevola kilaueae can also be propagated through division. This method is best done in the spring or early summer. Dig up the plant and cut the roots and stems in half using a sharp, sterile knife. Replant the divisions in well-draining soil and keep moist until they establish roots.
With proper care, Scaevola kilaueae can be easily propagated through any of these methods, and can be a beautiful addition to any coastal garden.
