Why do the leaves of tiger orchid become curly
Soil compaction, long-term replacement of soil, resulting in soil compaction, affecting water transport, so that leaves hair curl;Temperature is too low, winter growth temperature is too low resulting in frostbite, resulting in leaf roll;Watering too much, too much water or watering frequency is too high, resulting in basin soil water caused by root rot, so that leaves roll, wilting;Strong light, long-term exposure in the sun, easy to cause leaf edge coking, curling.1, soil compaction planting tiger orchid soil is not replaced for a long time, resulting in soil compaction, affecting water transport, roots can not normally absorb water and other nutrients, so that the leaves hair curl.It is recommended that the soil be replaced every two years, and the soil be loosened and ventilated regularly to ensure that the soil is loose and the soil has good air permeability.2, the temperature is too low, the cold resistance is poor, the appropriate growth temperature between 20℃ ~ 30℃, winter growth temperature can not be less than 10℃, too low temperature is easy to cause frostbite, leading to leaf roll.It is suggested to move to indoor warm environment for maintenance in winter, and avoid maintenance in air-conditioned rooms and next to electric heaters to prevent water shortage of leaves from affecting growth.3, watering too much tiger orchid drought resistance and waterlogging resistance, if in the breeding period, too much water or watering frequency is too high, resulting in basin soil water caused by root rot, so that leaves roll, wilting.So when watering, it should be appropriate to keep the soil in a dry state.In spring and autumn, it is suggested to water once a week. In summer, the weather is hot and the water evaporates quickly 3~5 days after watering. In winter, watering should be reduced for 10 ~ 15 days after watering.4, strong light for growth in the environment of adequate astigmatism, not long-term exposure in the sun, easy to cause the edge of the leaf coking, curly.In summer, when the light is too strong, it is necessary to carry out shading protection or breed in a semi-overcast environment. Do not insolate the tiger orchid under strong light to prevent sunburn on the leaves and affect the appreciation.
