WaterDahlias, including 'Le Castel', require consistent moisture and should be watered two to three times a week, depending on weather conditions. Ideally, provide 1 to 2 gallons of water per week during the growing season when there is insufficient rainfall. Water deeply at the base of the plant to encourage strong root growth and minimize water on the foliage to prevent fungal diseases. Ensure the soil is well-drained as Dahlias dislike waterlogged conditions. Reduce watering once the plants begin to die back in the fall.
LightDahlias prefer full sun conditions to thrive. Place 'Le Castel' Dahlia in a spot where it will receive at least 6 to 8 hours of sunlight per day. Avoid overly shaded areas as insufficient light can lead to poor blooming and weak growth.
TemperatureDahlias are sensitive to cold and 'Le Castel' thrives best in temperatures between 60 and 75 degrees Fahrenheit. They can survive minimum temperatures down to about 20 degrees Fahrenheit but must be protected or lifted in colder areas as they are not frost tolerant. Ensure the planting site offers some protection from extreme cold or heat for the best performance.
PruningPruning 'Le Castel' Dahlia is important for maintaining plant health and encouraging vigorous blooms. Deadhead spent flowers regularly to promote further blooming. Cut back plants to the ground after the first frost in the fall as part of preparing the plant for winter. Pruning also includes cutting stems for bouquets during the blooming period, which can encourage more blooms.
CleaningAs needed
SoilDahlias thrive in a well-draining soil mix with a slightly acidic to neutral pH of around 6.5 to 7.0. A good recipe for dahlia soil mix would be equal parts of garden soil, peat moss or coconut coir, and perlite or sand to ensure proper drainage. Feed with balanced, slow-release fertilizer.
RepottingDahlias typically do not require repotting as they are grown annually from tubers. However, the tubers should be lifted and stored during the winter in colder regions and replanted in the spring after the last frost date.
Humidity & MistingDahlias prefer moderate to slightly high humidity levels, but they are quite adaptable and can thrive in a range of humidity conditions as long as there is good air circulation around the plants to reduce the risk of fungal diseases.
Suitable locationsIndoor
Ensure bright light, good airflow, and pot with drainage.
Outdoor
Full sun, rich soil, good drainage, protect from strong winds.

Life cycleDahlia 'Le Castel' begins its life as a tuber planted in the spring after the last frost when the soil is warm. The tuber then germinates and sprouts stems and leaves, growing rapidly in rich soil with good drainage and full sun. During the summer, the plant develops a strong stem and leafy growth, followed by buds that bloom into vibrant flowers. Dahlias bloom from midsummer until the first frost, necessitating deadheading to encourage more blooms and maintain plant vitality. As temperatures drop in autumn, the plant's aerial parts begin to wither; this is when the tubers are typically dug up, cleaned, and stored during winter in a cool, frost-free place. The cycle recommences when the stored tubers are replanted the next spring.
PropogationPropogation time
Spring to Summer
Propogation: The most popular method for propagating the Dahlia 'Le Castel' is by division, which is typically performed in spring just before the new growth begins. This involves carefully splitting the tuberous root system, ensuring that each division has at least one eye or bud from which new growth can emerge. Dividers should use a sharp, clean knife to minimize damage and reduce the risk of disease. Once divided, the tubers can be planted directly into the ground or pots containing a well-draining soil mix, positioned about 4 to 6 inches (10 to 15 centimeters) deep with the eyes facing upwards. It is important to water these new divisions gently but thoroughly to help establish them.
