Dahlia Dahlia 'Barbarry Surprise'

Water

Dahlias require a consistent watering schedule and 'Barbarry Surprise' is no exception. Water the plants deeply two to three times a week, providing about 1-2 gallons per plant during each watering session, depending on soil type and weather conditions. Ensure the soil is well-draining to avoid waterlogging, which can cause rot. During periods of high heat, they may need more frequent watering. Always water at the base of the plant to keep the foliage dry and reduce the risk of fungal diseases.

Light

Dahlias thrive in full sun, and 'Barbarry Surprise' will do best with at least 6 to 8 hours of direct sunlight daily. Place the plant in a spot where it can soak up the morning sun and be protected from the intense afternoon heat if temperatures are extremely high. Avoid heavily shaded areas, as insufficient light can impede bloom production and lead to weak, elongated stems.

Temperature

Dahlias, including 'Barbarry Surprise', prefer moderate temperatures and grow best when daytime temperatures are between 70°F and 85°F. They can survive minimum temperatures down to about 50°F, but frost can be detrimental to them. During extreme heat, protective measures such as shade or mulching may be needed to keep the roots cool. The maximum temperature they can tolerate is around 90°F before they start to experience heat stress.

Pruning

Dahlias, such as 'Barbarry Surprise', benefit from pruning to encourage bushiness and more blooms. Pinch out the growing tips when the plant has reached about 16 inches tall to promote branching. Cut back spent flowers and deadhead regularly to stimulate new blooms. The best time for major pruning is early to mid-season, after flower buds have formed but before the plant is in full bloom.

Cleaning

As needed

Soil

Dahlia 'Barbarry Surprise', commonly known as Dahlia, thrives in a well-draining, fertile soil mix with compost and peat for moisture retention. Aim for a slightly acidic to neutral pH between 6.5 and 7.0. A blend of two parts garden soil, one part peat moss, and one part sand is ideal.

Repotting

Dahlias, including the 'Barbarry Surprise', should be repotted annually as they are typically grown as annuals and their tubers are lifted each fall after the first frost. Repotting ensures fresh soil and a chance to divide tubers if necessary.

Humidity & Misting

Dahlias like 'Barbarry Surprise' prefer a moderate humidity level but are adaptable to most ambient outdoor conditions, making specific humidity control unnecessary.

Suitable locations

• Indoor

  Place in bright, indirect light and ensure pot has good drainage.

• Outdoor

  Plant in well-draining soil, full sun, after frost risk passes.

• Hardiness zone

  8-11 USDA

Life cycle

The Dahlia 'Barbarry Surprise' begins its life cycle as a tuber planted after the last frost in well-drained soil and in a location with full sun. Sprouting occurs within a few weeks, where leaves and stems start to emerge, followed by the development of the plant's structure. Vegetative growth continues with the formation of lush foliage followed by the flowering stage, where distinct vibrant blooms appear, usually from midsummer until the first frost. After blooming, the plant enters a period of senescence as temperatures drop in autumn, with leaves and stems eventually withering. Before the onset of winter, the tubers are typically dug up and stored in a cool, frost-free place to overwinter. The cycle recommences the following spring when the tubers are replanted, repeating the annual growth, blooming, and dormancy sequence.

Propogation

• Propogation time

  Spring-Early Summer

• Dahlia 'Barbarry Surprise', like other dahlias, is most commonly propagated through tuber division. This method is best undertaken in the spring, after the danger of frost has passed but before the plant begins its active growth. To propagate by division, first carefully lift the tuber clump from the ground, ensuring minimal damage to the tubers. Wash off any soil, and allow the tubers to dry. Once dry, the clump can be divided by cutting between the individual tubers using a sharp, clean knife. Each section should have at least one eye, or growth point, from which the new plant will sprout. The divided tubers are then planted about 4 to 6 inches (10 to 15 centimeters) deep in well-draining soil and spaced approximately 18 to 24 inches (45 to 60 centimeters) apart to allow for ample growing space.
