A temperature of around 70-80°F (21-27°C) is ideal for the plant. The plant is sensitive to frost and cannot tolerate temperatures below 32°F (0°C). Cold temperatures can damage the leaves and the stem and may even lead to the plant's death.
Soil Requirements
Hawaiian poppy tree requires well-drained, fertile soil to grow properly. The soil should be rich in organic matter, and the pH level should be neutral to slightly acidic (6.0-7.0). The plant is susceptible to root rot, so the soil should be well-drained and moist but not waterlogged. Adding organic matter like compost to the soil can improve the soil's fertility and structure.
In conclusion, providing Hawaiian poppy tree with adequate light, warm temperatures, and well-drained, fertile soil is essential for its growth and survival. With proper care and attention, this beautiful and unique plant can grace your garden and enhance its beauty.
Cultivation Methods
The Claoxylon sandwicense Muell.-Arg. var. tomentosum Hbd., also known as the Hawaiian poppy tree, is a beautiful, slow-growing shrub that is endemic to the Hawaiian Islands. It is a relatively easy plant to grow and care for, with very few requirements. The plant can be propagated by seeds or cuttings.
The plant requires a well-draining soil that is slightly acidic with a pH of around 6.5. It also prefers bright, but indirect sunlight, making it a great choice for indoor or outdoor planting. The ideal temperature range for cultivation is between 60°F to 80°F.
Watering Needs
The Hawaiian poppy tree needs moderate watering. It is essential to avoid overwatering the plant as it can lead to root rot. Watering once a week is sufficient during the growing season, and during the dry season, it may need more frequent watering.
It is important to keep the soil moist but not waterlogged. Water the plant when the top one inch of soil feels dry to the touch. To avoid damaging the plant, water the soil rather than the leaves.
Fertilization
The Hawaiian poppy tree needs regular fertilization to maintain healthy growth. Fertilize the plant once a month during the growing season (spring and summer). Use a balanced fertilizer with slightly more nitrogen content to encourage leaf growth and root development.
Avoid fertilizing the plant during winter when it goes dormant. Over-fertilizing or using the wrong type of fertilizer can damage the plant.
Pruning
Pruning is essential to maintain the shape and size of the Hawaiian poppy tree. Prune the plant in the early spring before the start of the growing season. Remove any dead, diseased, or damaged branches and leaves.
The plant can be pruned to control its size and shape. Pinching back the tips of the branches can encourage bushy growth. To encourage flowering, prune the plant after flowering, leaving some of the old wood to produce new shoots.
Always use sterile pruning tools to avoid transmitting diseases to the plant.
Propagation of Claoxylon sandwicense Muell.-Arg. var. tomentosum Hbd.
Claoxylon sandwicense Muell.-Arg. var. tomentosum Hbd., locally known as uhiuhi, is a highly valued endemic Hawaiian plant that is commonly used for its medicinal properties. Propagation of this plant is usually carried out through vegetative means rather than sexual reproduction, as it ensures the preservation and propagation of plant characteristics that have been found to be desirable.
Vegetative Propagation
One of the main methods of propagating Claoxylon sandwicense is through stem cuttings. To obtain stem cuttings, healthy and vigorous stems should be chosen. The cuttings should be approximately 6-8 inches long and should be taken from the tip of the current season's growth. The cuttings should be treated with a rooting hormone to promote root formation. The cuttings should then be planted in a well-draining potting medium composed of organic matter, sand, and perlite. The cuttings should be misted regularly to prevent desiccation and should be kept in bright, indirect light until they have developed a well-established root system.
Another method of vegetative propagation of Claoxylon sandwicense is through air-layering. This method involves the creation of an incision on a healthy stem and wrapping it with a moist layer of sphagnum moss and plastic wrap. The moss should be kept moist to encourage root development. After several weeks, roots should emerge from the incision, and the rooted section of the stem can be removed and planted in a potting medium.
Tissue Culture Propagation
Claoxylon sandwicense Muell.-Arg. var. tomentosum Hbd. can also be propagated through tissue culture. In this method, small pieces of plant tissue can be cultured in a sterile nutrient medium. This method can be used to produce large quantities of plants in a small space and can be used to propagate rare or difficult-to-propagate plant species. However, tissue culture propagation requires specialized equipment and expertise and can be more time-consuming and expensive than other propagation methods.
In conclusion, Claoxylon sandwicense Muell.-Arg. var. tomentosum Hbd. can be propagated through stem cuttings, air-layering, and tissue culture. Vegetative propagation methods are preferred over sexual reproduction due to the preservation of desired plant characteristics. Careful attention to environmental conditions such as humidity, light, and temperature is necessary for successful propagation of this plant.

Diseases
Leaf Spot: Leaf spot disease is caused by various fungi that attack the leaves of the plant, leaving small brown or black spots on them. If left untreated, the leaves will eventually turn yellow and fall off, leading to stunted growth. To manage leaf spot, remove infected leaves and avoid overhead watering. Fungicides can be used in severe cases.
Root Rot: Root rot is caused by overwatering or poorly drained soil. It can lead to yellowing leaves, stunted or wilted growth, and even plant death. To manage root rot, ensure proper drainage by planting in well-draining soil and avoiding overwatering. Fungicides can also be used to control the disease.
Pests
Scale Insects: Scale insects are small, brown, oval-shaped insects that attach themselves to leaves and stems, sucking the sap from the plant and causing yellowing or wilting of the leaves. To manage scale insects, remove them manually or use insecticides such as neem oil or pyrethrin.
Aphids: Aphids are small, soft-bodied insects that suck the sap from the plant and cause yellowing or curling of the leaves. They can also secrete a sticky substance called honeydew, which can attract other pests and fungi. To manage aphids, remove them manually or use insecticides such as neem oil or soap sprays.
