How to Grow Carnations? Growing Methods and Precautions

Flowers & Gardening 0 views
To grow carnations, use loose, fertile, well-aerated flower soil with good water retention, a temperature of around 19-21°C, an appropriate amount of water, and plenty of sunlight. In addition, watch out for leaf spot disease, aphids, and red spider mites. If you want to propagate them, you can use cuttings or sowing.

I. Growing Environment

1. Soil. Carnations prefer loose, fertile flower soil with strong aeration and good water retention. For growing, it is best to choose sandy soil; do not use soil that is too heavy and sticky.

2. Temperature. Normally provide carnations with growing conditions of 19-21°C, and be careful to keep the temperature difference between day and night within 10°C. In winter, take certain cold-protection measures, and it is best to keep the temperature above 9°C; in summer, keep it below 35°C.

3. Water. Carnations are very afraid of waterlogging, so watering must never be excessive. Also, do not water too frequently in normal times; just water after the flower soil has dried out.

4. Sunlight. Carnations love sunlight very much. Normally you can let them receive full sun, but in summer you still need to provide appropriate shade. In addition, during their seedling stage and full blooming stage, appropriate shading is also needed.

II. Common Pests and Diseases

1. Leaf spot disease. If diseased spots appear on the stems or leaves, it may be this disease. This requires us to promptly remove diseased plants, stop watering, and then spray mancozeb or chlorothalonil for treatment.

2. Aphids, red spider mites, etc. If there are few insects on the carnation plant, we can physically remove them, then spray medicine to disinfect and kill the eggs. If there are many insects on the plant, you can pick off and destroy the diseased leaves, then spray omethoate solution for treatment.

3. Gray mold. If the carnation flowers, stems, or leaves are covered with gray mold-like material, it may have this disease. This requires us to promptly remove diseased plants, strengthen ventilation and light transmission, and spray chlorothalonil solution for treatment.

III. Propagation Methods

1. Cuttings. Cut healthy, disease-free branches about 10 cm long with nodes, insert them into the soil and water thoroughly, then place them in a shady place for about a week. After they grow roots, they can be placed in a sunny spot for care.

2. Sowing. This method is best chosen in early spring or early autumn. Adjust the temperature to around 20°C, then sow the carnation seeds onto previously prepared soil. Then cover with a thin layer of soil, water a little, and care for them slowly until they sprout.
