Growth conditions of Hedyotis glaucifolia (Gray) Fosberg var. helleri Fosberg
Light: Hedyotis glaucifolia var. helleri typically grows in a shaded or partially shaded environment. It can tolerate low to medium levels of light but does not thrive in direct sunlight.
Temperature: This plant is native to Hawaii and prefers warm temperatures with a range between 70-85°F (21-29°C). It can tolerate cooler temperatures but it may slow down growth. Frost or prolonged periods of cold weather can be harmful to its growth and survival.
Soil: Hedyotis glaucifolia var. helleri prefers well-draining soils that are rich in organic matter. It can grow in a variety of soil textures such as sandy, loamy, or clayey soils. A slightly acidic to neutral pH range of 6.0 to 7.0 is ideal for this plant's growth.
Water: Adequate moisture is important for the optimal growth of Hedyotis glaucifolia var. helleri. It requires regular watering, and the soil should not be allowed to dry out completely between watering. It is important to avoid waterlogging the soil as this can lead to root rot and other plant diseases.
Fertilizer: This plant benefits from regular fertilization during the growing season. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is recommended. The frequency of fertilization depends on the specific soil conditions, but a general guideline is to fertilize every 4-6 weeks.
Cultivation
Hedyotis glaucifolia var. helleri requires a warm and humid climate to grow properly. The ideal temperature range for this plant is between 18 to 26°C. It is a hardy plant that can grow in a variety of soil types, including sandy, loamy, and clayey soils. However, well-draining soil is recommended for the optimal growth of this plant.
The plant requires partial to full sun exposure for proper growth and blooms during the summer and fall season. It grows up to a height of 30-40 cm.
Watering
Hedyotis glaucifolia var. helleri requires moderate watering during the growing season. The plant needs to be watered once or twice a week, depending on the soil type and weather conditions. It is best to allow the soil to dry out before watering again. Overwatering can cause the roots to rot, leading to the death of the plant.
In winter, reduce the watering frequency as the plant becomes dormant during this period. Always ensure that the soil is not waterlogged as it can hamper the growth of the plant.
Fertilization
For optimum growth, the plant requires regular fertilization with a balanced fertilizer. Use a mild liquid fertilizer once a month during the growing season. Avoid using too much fertilizer as it can burn the roots and cause damage to the plant.
Organic fertilizers such as compost or manure can also be used, which provide essential nutrients to the plant. Apply these fertilizers to the soil during the spring season.
Pruning
Hedyotis glaucifolia var. helleri requires moderate pruning to maintain its shape and promote healthy growth. Prune the plant during the winter season by cutting back the stems to the desired length. This will encourage new growth and prevent the plant from becoming too leggy.
Remove any dead or diseased foliage regularly to prevent the spread of disease. Regular pruning will help to maintain a compact and bushy shape, which is beneficial for the health of the plant.
