Soil: Use sandy loam with good drainage. Light: Make sure there is enough light and the environment cannot be too dark. Moisture: Keep it slightly moist and do drainage during rainy season. Fertilization: Apply enough base fertilizer when planting, and apply liquid fertilizer once every 10 days during the growing season. Temperature: Give it a growing environment of 15-25℃, not lower than 10℃. In addition, do not expose it to the sun during maintenance.

1. Soil

1. Soil

When cultivating dahlias, they must fully meet their environmental requirements. Sandy loam with good drainage is generally provided with nutrient soil that meets the needs. Usually, five parts of garden soil are used. Mix two parts leaf mold soil, two parts sand and one part decomposed organic fertilizer to meet its soil requirements.

2. Light

Dahlia has relatively sufficient light requirements because it is a long-day flower. An environment that is too dark will cause the dahlia to grow elongated and bloom adversely, affecting the normal growth of the plant.

3. Moisture

Dahlia requirements The soil should be kept slightly moist, but should not be too dry or too wet. If it is summer, pay attention to drainage after rainfall to prevent water accumulation from causing damage to the root system.

4. Fertilization

Dahlias require sufficient fertilizer. Generally speaking, when planting bulbs in early spring, you need to apply a sufficient amount of decomposed organic fertilizer into the planting pot or land. , used as base fertilizer. Just apply a thin liquid fertilizer every 10 days or so during the growing season.

5. Temperature

Dahlia is A plant that is afraid of both cold and heat. Generally speaking, when the nighttime low temperature is below 10℃, it is necessary to prepare for cold protection. When the temperature at noon during the day reaches above 25℃, it is necessary to prepare for heatstroke prevention and cooling. The ideal growth temperature is between 15℃-25℃ so that it can grow better.

VI. Precautions

1. During the maintenance process, attention should be paid to avoiding sunlight exposure in summer and accumulation of water after rain. There are a lot of pests and diseases on dahlias, so you need to observe them at all times during the maintenance process, and control them in the early stages to avoid unnecessary damage.

2. Dahlias are relatively tall and have heavy flower heads. They may fall due to weather or human factors during the maintenance process. Generally, it is necessary to use pillars to support it in the middle and later stages of its growth. At the same time, because its root system is relatively large, it is best to bury the pillars in the soil when the bulbs are planted to avoid damage to the root system of the dahlia when the pillars are set up later, or even cause the bulbs to die.
