What problems do Phalaenopsis keikis cause, and do they need to be divided?
During Phalaenopsis care, the growth of side shoots (keikis) is a phenomenon that delights and confuses many growers. They are delighted by the vigorous growth of life, yet due to lack of experience they hesitate about how to handle the keikis. What effects does the appearance of keikis actually bring? And do they need to be divided?
Problems caused by Phalaenopsis growing keikis
Competition for nutrients: The roots of Phalaenopsis absorb a limited total amount of nutrients and water from the growing medium. When keikis grow, they compete with the mother plant for these precious resources. A large share of nutrients is diverted to supply the keikis, which may leave the mother plant unable to meet its own needs for normal growth, flower bud differentiation and blooming, resulting in thinner, yellowing leaves, slow growth, and even difficulty forming buds, seriously affecting flower quality and blooming period.
Limited growing space: As keikis continue to develop and grow, they occupy more and more growing space. In a limited pot, the keikis press against the mother plant and against each other, and ventilation and light penetration worsen. This crowded growing environment is not only unfavorable for photosynthesis but also prone to breeding pests and diseases, such as gray mold and red spider mites, further harming the health of the Phalaenopsis.
Decline in plant shape aesthetics: Naturally growing keikis often have rather random directions and positions, which may ruin the originally neat and elegant shape of the Phalaenopsis. Some keikis grow from the base of the leaves or other inappropriate positions, making the plant look messy, reducing its ornamental value and affecting the overall beauty.
Do Phalaenopsis keikis need to be divided:
Wanting to propagate new plants: If you want more Phalaenopsis plants, dividing keikis is an effective method of propagation. When a keiki grows to a certain size, usually with 3 - 4 roots and a length of about 5 - 10 cm, it can be divided. After carefully separating the keiki and planting it in fresh medium, with careful care the keiki can grow independently into a new plant, continuing the life of the Phalaenopsis and also saving the cost of buying new seedlings.
Mother plant severely affected: When keikis clearly hinder the growth of the mother plant, such as obvious poor growth or abnormal blooming, the keikis should also be divided in time to ensure the mother plant's health. When dividing, use a sharp and sterilized knife to minimize damage to the plant, and after cutting apply a disinfectant such as carbendazim to the wound to prevent infection.
Cases where division is not needed
Keikis are small and do not affect the mother plant: If the keikis have just emerged and are small, and the mother plant is growing well, there is no rush to divide them. Keep the keikis and let them continue growing for a while to observe their effect on the mother plant. During this process, reasonably control water and fertilizer to ensure both the mother plant and the keikis get enough nutrients.
Pursuing a special shape: Some growers pursue a unique ornamental effect and hope to use keikis to create a distinctive Phalaenopsis shape. In this case, division is not necessary; instead, by appropriate guiding and tying, the keikis can be directed to grow in the desired direction, creating a unique display.
The handling of Phalaenopsis keikis is not fixed; it needs to be chosen flexibly according to the plant's actual growth condition and personal needs. Whether you choose to divide them to propagate new plants or keep the keikis to create a unique shape, the premise is always to ensure the healthy growth of the Phalaenopsis. During care, careful observation and scientific handling are what allow the Phalaenopsis to bloom.
