How to solve the problem of dry and yellow leaf tips in hanging orchids in summer?
Hanging orchids have a graceful posture and remain green throughout the year. Moreover, this plant is relatively easy to care for, and even those without experience in gardening can grow it lush and thriving. However, it is common to observe yellowing and drying at the tips of the leaves when growing hanging orchids in summer. Many gardening enthusiasts simply cut off the dried parts, leaving the leaves uneven and affecting their ornamental value. So, what are the reasons for the yellowing and drying of the leaf tips in summer, and how should we deal with it?
One, too much sunlight
Hanging orchids prefer scattered light. In winter and spring, when the temperature is not too high, they can be exposed to more direct sunlight to maintain adequate light, which can make the plant grow more vigorously. However, in summer, they should not be placed in direct sunlight as the strong light can easily sunburn the leaves, causing the tips to dry. Once the tips are dry, they cannot recover and can only wait for new leaves to grow.
In summer, hanging orchids should be moved to a cool and well-ventilated environment in advance and can be exposed to scattered light appropriately, but never in direct sunlight.
Two, compacted potting soil
Hanging orchids grow quickly, and within a year, the roots can fill the pot. Over time, without repotting or changing the soil, the nutrients in the soil decrease, and it can easily become compacted, affecting the roots' ability to absorb nutrients normally. When nutrient supply is insufficient, the leaf tips gradually turn yellow and dry.
For hanging orchid plants at home, it is usually necessary to repot them every 1-2 years, replace the soil with loose and fertile potting mix, and prune the old and weak roots to enhance the absorption of nutrients by the roots.
Three, insufficient nutrients
Hanging orchids are mainly ornamental plants, so many gardeners rarely fertilize them, or even do not fertilize at all. This will not result in good growth. When nutrients are insufficient, not only will the tips of the leaves dry, but other leaves will also turn yellow, appearing less green and lacking vitality.
In addition to not fertilizing in winter, hanging orchids should be fertilized once a month in other seasons. If there is no time to fertilize regularly, a slow-release fertilizer with multiple elements can be applied in the pot. This way, even without frequent fertilizing, the plant can grow vigorously.
Four, prolonged drought
Those who have grown hanging orchids know that they are very drought-tolerant plants and will not have problems even if not watered for a week. However, if the potting soil and surrounding environment are too dry for a long time, it will affect the plant's normal growth. The most obvious sign is yellowing leaves and dried leaf tips.
Although hanging orchids are very drought-tolerant, they should not be allowed to lack water for a long time during the care process. Except for slightly dry soil in winter, the soil should be watered immediately when it feels dry in other seasons to allow the plant to grow quickly.
The humidity of the growing environment for hanging orchids is also very important. If the environment is too dry, it can lead to dry leaf tips, especially in summer when water evaporates quickly. Regularly spray the plant and its leaves to increase the environmental humidity to keep the plant in a vigorous and fresh state.
