Dianthus cultivation methods and precautions

How to grow dianthus

Planting

Dianthus is usually planted at the end of August. Prepare the potting soil, apply enough base fertilizer, and plant 5 to 6 seeds in each pot (to avoid germination). After sowing, thin out the seedlings when 1 to 2 leaves have grown. When 3 to 4 leaves have grown, it can be transplanted.

When transplanting, space each plant about 5 meters apart, with 3 plants in each pot, and water after planting.

Light and temperature requirements

The most suitable temperature for dianthus growth is 15~20℃. In summer, when the temperature is higher, pay attention to proper shading and cooling. In winter, it should be placed in a greenhouse and the temperature should be kept above 12℃.

Ensure sufficient sunlight during the growing period and place the flower pots outdoors in a sunny place. In summer, use mainly scattered light and avoid direct exposure to direct sunlight. Provide appropriate shade and cooling when the temperature is high.

Water and fertilizer requirements

When watering, you should follow the principle of not watering unless the soil is dry. For dianthus sown in autumn, you should pay attention to frost prevention when watering in November and December. For indoor maintenance, the water temperature should be close to the room temperature. Watering should be done when the temperature is higher at noon, and there should be no water accumulation on the leaves at night. In the spring of the second year, water the plants to restore green color, and the requirements are the same as in winter.

Top dressing should be done 2 to 3 times during the entire growing period, using decomposed cake fertilizer or organic fertilizer.

prune

If you want dianthus to bloom more, you need to prune it in time. When the plant grows taller, pinch the top to promote branching, remove leaf buds in time to reduce nutrient loss. After pruning, the dianthus will bloom again.

Things to note when growing dianthus

Hydrating and sun-shading

Ensure 6-8 hours of light every day. In midsummer, carnations are in a semi-dormant state, so care should be taken to avoid exposure to the sun. Avoid waterlogging in the pot soil, otherwise the roots will rot easily.

Pest and disease control

Dianthus does not suffer from many diseases and pests, the most common ones are calyx rot, rust, gray mold, bud rot, and root rot. Once the disease occurs, clean up the diseased plants in time and spray pesticides for prevention and control. Do not neglect it.
