You should provide indirect sunlight to the plant and keep it away from direct heat sources. In regions with hot weather, it is best to grow them indoors in a greenhouse to maintain the temperature.
Watering Needs
Orchids require adequate watering to grow properly, but overwatering can lead to root rot. Watering should be done with a gentle hand, and the soil should not be kept too wet. Before watering, touch the topsoil and water when it feels almost dry. Misting also helps to keep the foliage fresh and prevent the onset of dehydration due to dry environments.
Fertilization
Habenaria buchananiana Kraenzl. requires nutrient-rich soil for healthy growth. Fertilizing once a month with a balanced fertilizer, formulated with an equal ratio of nitrogen, phosphorus, and potassium, is optimal. Fertilizer should be applied during the growing season when the plant is actively growing. Avoid applying fertilizer during the resting period, as this can lead to fertilizer burn.
Pruning
Pruning is an essential aspect of orchid growth, and it helps keep the plant healthy and promotes flowering. After the plant finishes blooming, cut the stem a few centimeters above the last node. Regular pruning of old flower stems encourages the growth of new shoots, leading to a fuller, healthier plant. Pruning should be done with sterilized tools to prevent the spread of infections.
Propagation of Habenaria buchananiana Kraenzl.
Habenaria buchananiana Kraenzl., commonly known as Buchanan's Habenaria, is a terrestrial orchid found in India, Sri Lanka, and Bhutan. This orchid can be easily propagated through the following methods:
