6. Rosy periwinkle care for pest control
Rosy Periwinkle often suffers from rust, leaf rot, and rootworm, which can cause damage to its branches and leaves, and may even lead to wither and death.

7. Growing Rosy periwinkle care for leaves yellowing
Watering care. Too much watering, poor aeration caused by the pot soil leaves withered. Rosy periwinkle avoids wet and waterlogging, pot soil watering should not be too much, too wet affect growth and development. Open cultivation, summer showers, pay attention to timely drainage, lest waterlogging caused by the whole piece of death.
Correct method: When we grow and care for Rosy periwinkle, we had better to follow, avoid wet be afraid of waterlogging, do not not pour, pour is pour through 3 big principles.
Soil care. Some flower fans may not pay attention to a small detail, Rosy Periwinkle with alkaline, rigid, poorly ventilated clay soil, resulting in Rosy Periwinkle poor growth and yellow leaves.
Correct method: When we grow and care for Rosy periwinkle, we should supply appropriate fertile and drainage good soil person, endure barren soil.
Sufficient illumination care. Rosy periwinkle is a light-loving plant, which must be sunny during its growing period, with bright green leaves and bright flowers. If long-term growth in the shade, leaf yellow deciduous.
When we grow and care for Rosy periwinkle, Rosy Periwinkle is suitable for growth temperature above 20°, and a full sunshine environment is required. After the seedling emerges, it needs to be shaded for 2 ~ 3 hours in the noon with strong light and high temperature.
Rosy periwinkle care diseases and insects; If Rosy periwinkle do not pay attention to ventilation, long-term in the shade will lead to leaf rot, rust and root wart nematode growth, long-term pests will cause Rosy periwinkle leaf yellow.
When we grow and care for Rosy periwinkle, for leaf rot, spray with 65% Dezine WP 500 times liquid. Rust is sprayed with 50% wilting acid wettable powder 2000 times liquid.The nematode rhizoma was sprayed with 80% dibromochloropropane emulsion 50 times solution for control.
Fertilization care. Rosy periwinkle leaves can be too Rosy or too much fertilizer applied directly to the leaves.
