How to Plant Dahlias
Sharing some tips on how to plant dahlias and the timing and methods for planting, here are the details explained by the editor.
Dahlia Planting Time
Planting dahlias should be done in March to April of spring, controlling the temperature between 10-25°C. Before planting, it's necessary to pre-germinate the seeds, thoroughly disinfect the soil, and loosen the soil while fertilizing. After planting, water and keep the soil moist.
Dahlia Planting Methods
1. Seed Treatment: Before planting, clean the disinfected seeds with water, then soak the seeds in a dilute solution of chloronitrobenzene.
2. Soil Requirements: The soil for planting dahlias should be rich in nutrients and sandy. Before planting, deeply turn the soil and mix garden soil, humus, and river sand.
3. Planting: The best time to plant dahlias is between March and April in spring. Place the seeds evenly in the soil and cover them with soil.
4. Post-Planting Management: During the germination period, dahlias need to be shaded appropriately. Once the seedlings are even, remove the plastic film and transplant the seedlings to a sunny area.
5. Cultivation Management: Dahlias are plants that require a lot of fertilizer. In the early growth stage, the plants must be provided with ample nutrients and additional cake fertilizer can be applied according to the plant's growth.
How to Plant Dahlia Just Bought
1. Check the Plant Condition: After purchasing dahlias, check the plant's growth condition to observe if there are any diseases on the roots and leaves.
2. Acclimatization: Place the newly bought dahlias in a shady area, enhance ventilation, open windows frequently to promote air circulation. Once the plant's branches and leaves have spread out and new leaves have grown, the acclimatization is considered successful.
3. Timely Pruning: Dahlias may develop yellow leaves due to adaptation issues. It's necessary to prune these leaves to reduce nutrient consumption.
How to Make Dahlias Grow Fast
1. Light Requirements: Dahlias require plenty of sunlight, needing more than 6 hours of sun exposure daily to ensure growth.
2. Soil Requirements: Dahlias have specific soil requirements, needing well-draining and loose soil.
3. Suitable Temperature: Dahlias prefer cool weather and are sensitive to heat. They grow best in a 20°C environment. In North China, from late spring to deep autumn is the most suitable growing period.
4. Watering: Overwatering or underwatering is not recommended. During the growing period, water 2-3 times a day, and control watering appropriately before flowering.
5. Fertilizing: In addition to maintaining sufficient base fertilizer, timely top-dressing is necessary. From mid-July to before flowering, apply a light liquid fertilizer every 7-10 days.
Attention Points for Dahlia Potted Plant Cultivation
1. Staking: Dahlia stems are fragile and can be easily blown over by the wind. Therefore, when the plant grows to over 30 centimeters tall, it's necessary to stake it with bamboo to enhance the ornamental value.
2. Ensuring Winter Survival: Dahlias are not frost-hardy. After the leaves wither in winter, prune the above-ground parts and move the plant indoors for care.
