Reasons for the Drying of Ivy Leaves
Core introduction to the main text: Reasons for the drying of ivy leaves and related information on remedies for ivy wilt in green plants. Detailed content will be shared next.
China is one of the original habitats of ivy, with different types of ivy commonly grown at home, including Chinese ivy, variegated ivy, and English ivy. There are about 14 species of ivy, totaling hundreds of varieties. It is an evergreen climbing shrub that is prone to leaf drying issues. Let's understand the reasons for the drying of ivy leaves.
One, Improper Watering
1. Soil too wet or waterlogged
Watering should not be excessive, as overly wet soil can lead to root rot, causing leaves to wither, initially affecting young leaves that turn yellow and then dry up, followed by old leaves.
2. Soil too dry
Ivy prefers moisture, and if not watered for too long, the plant's lack of water can cause leaves to dry.
3. Incorrect watering method
Suddenly pouring cold water during high temperatures can also cause leaves to dry. The water temperature needs to be close to the ambient temperature.
Two, Diseases and Pests
1. Diseases
Infected plants with leaf spot disease will have yellow leaves, initially showing light green spots on the leaves, which then turn into larger brown or black spots, causing the leaf stems to dry and the leaves to turn yellow and fall off. Leaf spot disease often occurs in warm and humid rainy seasons and requires timely pruning of diseased branches and leaves, watering the base of the plant, and treating with Bordeaux mixture, as well as soil disinfection.
2. Pests
Scale insects and red spiders can cause partial drying and leaf drop. Poor indoor ventilation in summer can lead to red spider infestations, so attention must be paid to maintaining good air circulation and taking cooling measures during summer cultivation.
Three, Low Temperature
Ivy prefers a cool environment and will temporarily hibernate when the temperature exceeds 30°C. It is also not cold-tolerant, and frost can cause leaves to turn yellow and dry. Leaves can also wither when the temperature is below 5°C.
Four, Inappropriate Light
Both excessive sunlight exposure and insufficient light can cause ivy leaves to dry. High-temperature environments with strong sunlight can cause young leaves to dry at the tips, leaf edges to turn yellow, and even leaf drop. Although it adapts to direct sunlight and is shade-tolerant, it must avoid strong sunlight to prevent sunburn and should not be kept in a dark environment for long, as this can cause thin and fragile branches and leaves, making them prone to drying under high-temperature stress and dry conditions.
Five, Insufficient Air Humidity
Excessively dry air can cause leaves to dry. It is necessary to maintain appropriate air humidity to keep the leaves fresh and green. Especially in northern regions, where indoor air is very dry in winter, you can use water close to room temperature to wash the leaves or spray them.
Six, Improper Fertilization
1. Incorrect fertilization method
When fertilizing, do not let the fertilizer water touch the leaves, as this can cause leaf drying.
2. Insufficient fertilizer
Lack of fertilizer, such as nitrogen and iron, can cause leaves to become thin and yellow. During the vigorous growth period, it is generally necessary to apply fertilizer once every 15 to 20 days, with a thin application of cake fertilizer water.
3. Excessive fertilizer
Excessive fertilization can cause root burn, leading to yellowing of old leaves and even leaf drop.
Seven, Fertilizer Burn
High concentrations of pesticides can cause leaf drying, appearing as leaf tips or parts of leaf tissue burning, and even plant death.
Eight, Soil Incompatibility
Ivy prefers well-drained and loose soil. If the soil compacts, it can cause the plant to lack water, leading to leaf drop.
Nine, Poor Ventilation of the Plant
If the branches and leaves are too dense or the environment has poor ventilation, it can also cause leaves to dry.
