How do dahlias survive the winter?

Dahlia is a plant of the Asteraceae family and the genus Dahlia. It is a perennial herb. This plant is famous for its large, beautiful and colorful flowers and is a world-renowned ornamental flower . So when caring for dahlias in winter, how can we ensure that they can safely survive the winter? Let’s learn more about it below.

1. Temperature management

Move dahlia pots or bulbs into a greenhouse or indoors. Keep the temperature between 10-15°C, avoiding too high or too low temperatures.

2. Provide enough light

The light is weaker in winter, but dahlias still need proper light for photosynthesis. If you are planting dahlias in the ground, you should choose a sunny place for covering. If it is a potted dahlia, it should be placed in a sunny location indoors.

3. Control watering

Dahlias grow slowly in winter, so the amount of watering should be controlled moderately. Pay attention to the moisture of the soil and water appropriately only when the soil surface is dry. Excessive watering can cause root rot, which can affect the growth of the plant.

4. Stop fertilizing

In winter, dahlia plants will enter a dormant state, their metabolism will slow down, and they will not absorb nutrients. Fertilizing them will result in a waste and may even cause root burns. Therefore, fertilization should be stopped in winter.

5. Proper pruning

Winter is also a good time to prune dahlias to remove yellow leaves and unhealthy branches, ensuring that nutrients are better distributed to healthy parts. You can apply fertilizer in moderation after pruning, but avoid excessive fertilization to avoid stimulating excessive growth of dahlias.

6. Regular inspection

Check the condition of the bulbs regularly. If the root tubers are found to be rotten, the temperature must be lowered and moved to a dry and ventilated place. In addition, we must also pay attention to the intrusion of pests and diseases, discover them in time, and deal with them in time.

7. Replanting

After wintering, when the temperature warms up in spring, you can move the dahlia pots outdoors, and the bulbs that were previously stored can be taken out and replanted in pots. After planting, water it appropriately and expose it to sunlight properly, waiting for the dahlia to bloom again.

In general, dahlias are warmth-loving plants that are not cold-tolerant and require special care in winter to ensure their health. By using the above methods, you can ensure that your dahlias safely survive the winter and resume growing in the spring.
