Correct maintenance tips for Dutch chrysanthemums in winter

Dutch aster , also known as New York aster and willow-leaf daisy, likes a ventilated and humid growing environment and has strong adaptability. Dutch chrysanthemums are colorful and naturally formed, with high ornamental value. They are often used as materials for flower beds and flower borders, and can also be planted in pieces, clusters, or as potted flowers. Below, the editor will introduce the correct maintenance points of chrysanthemums in winter. Let’s take a look.

1. Temperature control

Chrysanthemums have good cold resistance. Ground-planted chrysanthemums can withstand temperatures as low as -10℃, but potted chrysanthemums have poor cold resistance and can only withstand temperatures as low as 0℃. Therefore, the ambient temperature should be kept above 0℃ in winter to avoid frostbite on the plants. If the temperature is too low, you can use plastic film to cover and protect the roots, or move the potted plants indoors.

2. Lighting requirements

Chrysanthemums like a sunny environment and need sufficient light even in winter. At least 4 hours of sunshine a day is needed to ensure the healthy growth of the plant.

3. Watering management

In winter, the transpiration of chrysanthemums weakens and the water requirement decreases. The frequency of watering should be reduced and the soil should be kept slightly moist to avoid water accumulation and excessive moisture that may cause root rot.

4. Fertilization control

Chrysanthemums grow slowly in winter and their demand for nutrients decreases accordingly. Therefore, the frequency and amount of fertilization should be reduced in winter. If the plant grows vigorously, you can apply some dilute liquid fertilizer in the early stages of growth, such as decomposed cake fertilizer water. But be careful to avoid too high a concentration of fertilizer or allowing it to get on the leaves to avoid burning the plants. During the flower bud differentiation period, you can apply appropriate amounts of phosphorus and potassium fertilizers to promote flower bud differentiation and flowering.

5. Pruning

Before winter comes, chrysanthemums should be pruned by shortening the stems and branches to reduce winter stress and retain a certain number of buds, which will help the growth of new buds. Use sharp scissors when pruning and sterilize them to avoid wound infection.

6. Pest and disease control

In winter, chrysanthemums are susceptible to diseases and pests. You should choose covering materials that can prevent pest invasion and deal with diseases and pests in a timely manner when they are found.

The above is an introduction to the correct care points for chrysanthemums in winter. In particularly cold areas, chrysanthemums need to be maintained indoors. Place it in a sunny location and keep the indoor temperature between 18-21 degrees Celsius.
