Dahlia Dahlia 'Shep's Memory' (WL)

Water

For the Dahlia 'Shep's Memory', commonly known as dahlia, the watering needs are moderate, preferring a consistent schedule. Water the plant deeply once or twice a week, allowing the soil to dry out slightly between waterings. During the peak growth season, in spring and summer, dahlias may need more frequent watering, especially in hotter climates. Aim for about 1-2 gallons per plant for each watering, depending on the soil type and weather conditions. Always avoid overhead watering to minimize the risk of disease and wet foliage.

Light

Dahlias thrive best in a location that receives full sunlight, around 6 to 8 hours of direct sunlight each day. They can tolerate partial shade, but they will produce fewer blooms in lower light conditions. Choose a spot in your garden that is well-lit and receives morning sunlight, which is less harsh and helps dry the dew on the leaves, reducing disease risk.

Temperature

Dahlias prefer a temperate climate with a temperature range between 60°F and 75°F for optimal growth. They can survive in temperatures as low as the upper 40s°F but should not be exposed to frost, as it can kill the plant. Conversely, high temperatures over 90°F can stress the plant, so provide shade or mulch to help regulate soil temperature and retain moisture during extreme heat.

Pruning

Pruning dahlia plants helps to promote bushier growth and more flowers. Deadhead spent blooms regularly to encourage continual blooming throughout the season. Additionally, practice pinching out the tips of young plants to stimulate branching. The best time for pruning dahlias is late winter to early spring, before new growth begins. Cut back any old or dead foliage to maintain plant health and vigor.

Cleaning

As needed

Soil

Dahlias thrive in well-draining soil with a pH of around 6.5. A mix containing loam, peat moss, and sand is ideal to ensure proper drainage while retaining adequate moisture. Incorporating compost into the soil mix can also provide necessary nutrients for optimal growth.

Repotting

Dahlias, including 'Shep's Memory', should be repotted annually, typically in the spring. This allows the tubers to be divided if necessary and gives the plant fresh soil with renewed nutrients.

Humidity & Misting

Dahlias prefer a moderate humidity level, avoiding conditions that are too dry or excessively humid. Consistently high humidity can promote fungal diseases, so ensuring good air circulation around the plants is crucial.

Suitable locations

• Indoor

  Ensure full sun, rich soil and space for tubers.

• Outdoor

  Full sun, fertile soil, regular watering, staking.

• Hardiness zone

  8-11 USDA

Life cycle

Dahlia 'Shep's Memory', commonly known as Dahlia, begins its life cycle as a tuber planted after the last frost when the soil has warmed. The tuber will sprout and grow into a bushy, flowering plant throughout the spring and summer, requiring ample sunlight and water. Blooms typically appear mid-summer and can continue until the first fall frost, showcasing its vibrant flowers. After flowering, Dahlias enter a period of dormancy in autumn when the foliage dies back with the onset of cooler temperatures. In regions with freezing winters, the tubers are often dug up and stored in a cool, dry place until the next spring. The cycle repeats when the stored tubers are replanted after the frost, making Dahlias perennial through this process of overwintering in cold climates.

Propogation

• Propogation time

  Spring-Early Summer

• Dahlia 'Shep's Memory', commonly known as dahlia, is typically propagated by division of its tuberous roots, which is best done in the spring when the plant is beginning to grow new shoots. The process involves digging up the clump of dahlia tubers very gently to avoid damage, and then using a sharp, clean knife to slice between the tubers, ensuring that each division has at least one eye, or bud, from which new growth will sprout. These divisions can then be planted directly into prepared beds, ideally with the top of the tuber positioned about 2-3 inches (5-7.5 cm) below the soil surface. The soil should be well-draining and rich in organic matter to support the growth of new plants. Once planted, it’s important to water the divisions sparingly until new growth becomes more evident, indicating that the plant has established itself and is beginning to grow. This method encourages a high success rate and keeps the garden filled with these vibrant flowers year after year.
