Temperature Requirements
The optimal temperature range for the growth of Pelesia hawaiensis Wawra is between 60°F to 75°F (15.5°C to 24°C). The plant cannot tolerate extremely low temperatures, and if exposed to temperatures below 50°F (10°C), its growth may stall.
Soil Conditions
Pelesia hawaiensis Wawra prefers to grow in well-drained soil that is rich in organic matter. The soil pH should be between 5.5 to 6.5 for optimal growth. The plant is not salt-tolerant, and it's recommended that you avoid planting it near salt-laden areas.
Cultivation
To cultivate Pelea hawaiensis Wawra, it's essential to select a well-draining potting mix and a location that gets plenty of sunlight. The plant prefers an acidic soil with a pH ranging from 4.5 to 5.5. The ideal temperature range for growth is 60-80°F. The plant is sensitive to cold temperatures and should not be exposed to frost.Watering Needs
Pelea hawaiensis Wawra requires moist soil but not wet. Water your plant once a week, ensuring that the soil is moist one inch below the surface. Plants in sandy soil may need more frequent watering, while those in heavy clay soil require watering less frequently. Avoid splashing water on the leaves, as this can cause fungal problems.Fertilization
Fertilize Pelea hawaiensis Wawra using a balanced fertilizer with an N-P-K ratio of 10-10-10. Apply the fertilizer once a month during the growing season, which is from spring to fall. Use a liquid fertilizer at half strength and reduce to one-quarter strength for young plants.Pruning
Pelea hawaiensis Wawra requires minimal pruning. Remove dead and yellowing leaves to maintain the plant's appearance and prevent fungal issues. Prune off the spent flowers to encourage blooming. Always use sharp and clean pruning tools to prevent the spread of disease.Propagation of Pelea hawaiensis Wawra
Pelea hawaiensis Wawra, commonly known as Ohe or Hawaiian stinkwood, is a small tree in the family Rutaceae that is endemic to the Hawaiian Islands. The plant is known for its attractive foliage and fragrant flowers, and it is commonly grown in gardens and as a houseplant.
Propagation of Pelea hawaiensis Wawra can be done through seed or vegetative methods.
Seed propagation
Seeds of Pelea hawaiensis Wawra are typically collected from mature fruits that have fallen from the tree. The seeds should be cleaned and sown in a well-draining potting mix in a small nursery container. The container should be placed in a warm and humid environment until germination occurs, which usually takes around 2 to 4 weeks.
Once the seedlings have emerged, they can be transplanted into larger containers and grown until they are large enough to be planted in their final location. It should be noted that seed-grown plants may not be true to the parent plant and may exhibit genetic variability.
Vegetative propagation
Vegetative propagation of Pelea hawaiensis Wawra can be done through cuttings or layering. Cuttings should be taken from mature plant material, preferably from the tip of the stem. The cuttings should be dipped in rooting hormone and planted in a well-draining potting mix. The container should be placed in a warm, humid environment until the cuttings have rooted, which usually takes around 4 to 6 weeks.
Layering involves bending a low-growing branch so that it comes into contact with the soil. The branch should be wounded where it touches the soil, and rooting hormone should be applied. After the roots have formed, the branch can be cut from the parent plant and transplanted into its final location.
Overall, Pelea hawaiensis Wawra is a relatively easy plant to propagate using either seed or vegetative methods.
