Soil requirements
Pelea wawraeana Rock var. pubens St. John prefers well-draining soils with a slightly acidic to neutral pH. The species can tolerate some soil moisture, but overwatering can lead to root rot. This species can grow well in a variety of soil types, including loam, sand, clay, and volcanic soils.
Cultivation methods for Pelea wawraeana Rock var. pubens St. John
Pelea wawraeana Rock var. pubens St. John is native to Hawaii and requires a warm climate to thrive. It is best grown in tropical or subtropical regions where temperatures range from 60 to 80 degrees Fahrenheit. Pelea wawraeana Rock var. pubens St. John can be grown in full sunshine or partial shade and requires well-draining soil. If you’re growing the plant indoors, you should provide it with a suitable potting mix that drains well, or combine sand and peat moss with regular soil mix to improve drainage.
Watering needs
Pelea wawraeana Rock var. pubens St. John requires moderate watering. Allow the top inch of soil to dry out before watering to prevent overwatering. When you water, thoroughly soak the soil until the water runs out the drainage hole. If you’re growing the plant indoors, make sure to empty the saucer underneath the pot after watering as standing water can cause root rot.
Fertilizing
To improve growth and flowering, fertilize Pelea wawraeana Rock var. pubens St. John during the growing season (spring and summer) with a balanced liquid fertilizer. Dilute the fertilizer to half strength and apply every four to six weeks. Avoid fertilizing in the winter when the plant is dormant.
Pruning
Pelea wawraeana Rock var. pubens St. John requires minimal pruning. Remove any dead or damaged leaves or stems as needed. If the plant becomes leggy, pinch back the stems to encourage bushier growth. Prune in the spring before new growth appears. Avoid over-pruning as it can stunt the growth of the plant and reduce flower production.
Propagation methods of Pelea wawraeana Rock var. pubens St. John
Propagation of Pelea wawraeana Rock var. pubens St. John can be done through:
Seed propagation
The easiest method to propagate Pelea wawraeana is through seed. The seeds can be directly sown in a pot or container filled with well-draining potting mix. It is best to sow the seeds in spring as the temperatures start warming up. Bear in mind that the seeds need a period of cold stratification to germinate, usually for 8-10 weeks. Once the seeds germinate, they can be moved to a larger container or outside when the seedlings have grown enough to handle the transplant.
Cuttings propagation
Propagation of Pelea wawraeana can be done using softwood cuttings, semi-hardwood cuttings, or hardwood cuttings. Softwood cuttings can be taken in spring, semi-hardwood cuttings in summer, and hardwood cuttings from late fall to winter when the plant is dormant. Remove the leaves from the bottom half of the cutting, dip the cut end in rooting hormone, and plant it in a container with well-draining potting mix. Keep the cutting in a warm and humid environment to allow the roots to develop. The cutting can be transplanted after several weeks of rooting.
Air layering
Air layering is a propagation method suited for mature plants that are hard to propagate using cuttings. It involves making a wound in the stem and packing it with moist growing medium until roots develop. Once roots have developed, the stem can be cut off and planted as a new plant. Air layering works best in spring or early summer when the plant is actively growing.
Disease and Pest Management for Pelea wawraeana Rock var. pubens St. John
Pelea wawraeana Rock var. pubens St. John is a tropical plant that belongs to the Rutaceae family. It is also known as the "Wawra Pelea."

Leaf spots: Leaf spots on Pelea wawraeana can be caused by fungal and bacterial infections. These infections can cause the leaves to have brown or black spots and may spread to other parts of the plant, causing it to wither and eventually die. To manage leaf spot diseases, remove any affected leaves and avoid watering the plant from above. Use a copper fungicide spray on the plant to prevent the spread of the disease.
Powdery mildew: This fungal infection appears as white powder on the foliage of the plant. It can be caused by high humidity and poor air circulation around the plant. To manage powdery mildew, remove any affected leaves and prune the plant regularly to improve airflow. Apply neem oil or a fungicide spray specially formulated for powdery mildew.
Root rots: Root rots are common in Pelea wawraeana, especially when overwatered. It can be caused by fungal or bacterial infections and can cause the plant to wilt and die. To manage root rot, carefully remove the plant from the soil and trim any affected roots. Repot the plant in fresh soil with perlite or sand added to improve drainage.
Common Pests
Aphids: Aphids are tiny insects that can suck the sap from the leaves of Pelea wawraeana, causing them to deform and wilt. To manage aphids, spray the plant with insecticidal soap or neem oil. You may also introduce ladybugs to the affected plants as they are natural predators of aphids.
Spider mites: Spider mites are small pests that feed on the plant's sap, causing yellowing and dryness of the foliage. They can be removed by spraying the plant with water regularly or applying insecticidal soap. You may also introduce predatory insects like lacewings or mites to manage the infestation.
Mealybugs: Mealybugs are small white insects that suck the sap from the plant's leaves. They can be removed by rubbing them with cotton swabs soaked in rubbing alcohol or applying insecticidal soap. You may also introduce predatory insects like ladybugs or parasitic wasps to manage the infestation.
Managing pests and diseases in Pelea wawraeana is essential to keep the plant healthy and in good condition. Keeping the plant clean and well-maintained can go a long way in preventing these problems. Applying preventive measures regularly can also help keep pests and diseases at bay.
