How to Care for Ivy in Summer
As a widely popular ornamental foliage plant, the summer care of ivy is directly related to the health of the plant. During the hot season, special attention should be paid to the three key elements: temperature control, light management, and water supply. Scientific care can effectively prevent issues like yellowing leaves and burnt edges, keeping the vines lush and green.
1. Temperature Control Techniques
1.1 Ideal Temperature Range
The optimal growth temperature for ivy is between 18-23°C. When the ambient temperature exceeds 28°C, the leaves' respiration accelerates, and it is recommended to immediately move the plant to an air-conditioned room or a north-facing balcony. During the high-temperature periods of July and August, auxiliary cooling methods such as sprinkling water on the ground or hanging wet curtains can be used.
1.2 Ventilation Precautions
Maintaining air circulation can effectively prevent pests like red spiders, but it is necessary to avoid strong midday convective winds. It is recommended to open windows for ventilation for one hour in the morning and evening, combined with a circulating fan to create gentle air movement.
2. Light Management Plan
2.1 Specifications for Using Sunshade Nets
Choose a silver sunshade net with a shading rate of 40-50%, and keep it at a distance of more than 50cm from the plant. It must be covered from 10:00 to 16:00 daily, while soft scattered light can be accepted during dawn and dusk.
2.2 Emergency Treatment for Sunburn
When yellowish-white burn spots appear, immediately cut off the damaged leaves, spray with a diluted solution of 2000 times rapeseed hormone, and move the plant to a shaded area for two weeks of care.
3. Water Supply Strategy
3.1 Scientific Watering Schedule
Adopt a double-watering mode of watering thoroughly in the morning and supplementing in the evening, with the water temperature matching the room temperature. Use a long-spouted kettle to water slowly along the pot wall, avoiding water accumulation on the leaves that could cause diseases.
3.2 Method for Maintaining Humidity
Combine the method of using a pot-within-a-pot for water storage: place a layer of wet ceramsite in the outer pot and put a 3cm high wooden block under the inner pot, maintaining 60% air humidity through evaporation.
Through the integrated management of temperature, light, and water, ivy can not only safely survive the summer but also maintain a vigorous growth state. It is recommended to check the potting soil condition every 10 days and adjust the care plan in a timely manner to showcase the best ornamental effect of the vine plant.
