WaterDahlias require consistent moisture, so it's best to water them deeply 2 to 3 times a week, adjusting for weather conditions. The amount of water needed can vary, but a general rule is to use about 1 to 2 gallons per plant for each watering session. Ensure the water reaches the roots by applying it directly to the base of the plant without wetting the foliage to prevent disease. In hot, dry weather, more frequent watering may be necessary to keep the soil evenly moist. Always check the soil before watering; it should be moist but not waterlogged.
LightDahlias thrive in full sun, meaning they need at least 6 to 8 hours of direct sunlight daily. The best spot for a Dahlia plant is in an area where it receives this sunlight during the morning and early afternoon hours. Partial shade in the hottest part of the day can help prevent heat stress during peak summer months.
TemperatureDahlias grow best in temperatures ranging between 60°F and 70°F, which are ideal for their growth. They can survive in temperatures as low as 50°F at night and can handle daytime temperatures up to the low 90s°F. However, extreme temperatures outside of this range could lead to poor growth or even damage to the plant.
PruningPruning, also known as deadheading, encourages Dahlias to produce more flowers and prevents the plant from expending energy on seed production. Cut spent flowers back to the next full set of leaves to promote bushier growth and more blooms. This should be done throughout the blooming season, which is typically from midsummer until the first frost. The best time for more extensive pruning or cutting back is in the fall after the first frost when the plant begins to die back naturally.
CleaningAs needed
SoilDahlias thrive best in a well-draining, fertile soil mix with a pH of 6.5-7.0. A good mixture can be made using equal parts garden soil, peat moss, and perlite or sand to encourage proper drainage and aeration. Incorporating compost or a balanced slow-release fertilizer will supply essential nutrients for optimal growth.
RepottingDahlias, particularly the 'Hootenanny - Swan Island' variety, are often grown as annuals and thus don't require frequent repotting. If grown as perennials, they may be lifted and divided every 2-3 years to maintain vigor and flower size.
Humidity & MistingDahlias prefer moderate humidity levels. While they tolerate a range of humidity conditions, it's important to avoid excessively high humidity to prevent issues such as fungal diseases. Ample air circulation around the plants will help maintain the ideal humidity.
Suitable locationsIndoor
Provide bright light, keep soil moist but not wet.
Outdoor
Plant in full sun, ensure good soil drainage.

Life cycleThe Dahlias life cycle begins with seed germination or tuber sprouting in early spring, when the soil has warmed and risk of frost has passed. Seedlings or shoots grow into sturdy stems and foliage, utilizing warm temperatures and adequate moisture throughout the spring and summer. Bud formation occurs as the days get longer and temperatures rise, leading to the blooming phase where 'Hootenanny - Swan Island' displays its vibrant flowers typically from midsummer until the first frost. After the blooming phase, as temperatures drop and daylight decreases, Dahlias enter a period of dormancy. During this stage, the above-ground parts die back, and the tubers can be dug up and stored in a cool, dry place to overwinter. In the following spring, the cycle can be restarted by replanting the tubers after the last frost has passed.

Spring-Early Summer
Dahlias, including the 'Hootenanny - Swan Island' cultivar, are most commonly propagated through division of their tubers, which is best carried out in the springtime when new sprouts are visible. The tubers are carefully dug up and washed to allow for clear visibility of the eyes, which are the points from which new growth will sprout. Using a sharp, sterile knife, the tuber is cut into sections, ensuring each piece has at least one eye. The cut surfaces need to dry and callous over for a day or two to prevent rotting when planted. These divided tubers can then be planted directly into the garden, usually about 6 to 8 inches (15 to 20 centimeters) deep, and spaced around 18 to 24 inches (45 to 60 centimeters) apart. This method leverages the plant's natural growth cycle and ensures new plants will have characteristics identical to the parent.
