Dahlia ‘Caproz Pizzazz’ is a highly sought-after variety, celebrated for its unique aesthetic appeal. This dahlia brings distinct vibrancy to any garden space, making it a popular choice for continuous bloom. Its appeal reflects the general fascination with dahlias, which offer an impressive array of forms and colors, transforming gardens into dynamic floral showcases.
Understanding ‘Caproz Pizzazz’ Dahlias
The ‘Caproz Pizzazz’ dahlia features large, double flowers with a captivating color transition. Its petals typically start with a white or pale pink center that gradually deepens to rich purplish-fuchsia or magenta hues at the tips. This striking bi-color effect creates a visually dynamic bloom that stands out in borders or as a cut flower.
The blooms usually measure between 2 to 4 inches across, classifying them as decorative or ball-shaped dahlias. The ruffled and full nature of the petals contributes to its stunning appearance. This variety also produces lush, leafy foliage, with plants typically reaching heights of 32 to 36 inches.
Planting ‘Caproz Pizzazz’ Dahlias
‘Caproz Pizzazz’ dahlia tubers should be planted in the spring after the last frost has passed and the soil temperature consistently reaches 60°F (15°C). These dahlias thrive in locations that receive full sun, ideally at least six hours of direct sunlight daily.
Well-draining soil is crucial for dahlias, as they will not tolerate waterlogged conditions. Amending the soil with organic matter such as compost or aged manure can improve drainage. When planting, dig a hole 3 to 4 inches deep, placing the tuber with the “eyes” facing upwards. Space tubers approximately 18 to 24 inches apart. After planting, avoid immediate watering; instead, wait until sprouts appear above the soil line to prevent rot.
Ongoing Care for ‘Caproz Pizzazz’ Dahlias
Consistent watering is important for ‘Caproz Pizzazz’ dahlias once they have sprouted. Deep watering, less frequently, is generally more beneficial than shallow, frequent watering, allowing roots to seek moisture deeper in the soil. Applying mulch around the base of the plants can help retain soil moisture.
Dahlias benefit from regular fertilization throughout the growing season. A balanced fertilizer or one higher in phosphorus can promote strong blooms. For taller varieties like ‘Caproz Pizzazz’, staking or providing support is necessary to prevent stems from breaking. Placing stakes at planting time can prevent damage to the tubers later. Deadheading, the removal of spent flowers, encourages the plant to produce more buds and prolongs the blooming period from midsummer until the first frost.
Overwintering Dahlia Tubers
In regions with cold winters (USDA Hardiness Zones 3-7), ‘Caproz Pizzazz’ dahlia tubers are not winter hardy and must be stored indoors. The ideal time to dig them is after the first hard frost has caused the foliage to turn dark brown, but before the ground freezes. Allowing the tubers to remain in the ground for one to two weeks after a light frost can help their skins toughen, improving storage viability.
Cut the stems down to about 4 to 6 inches, then carefully loosen the soil around the tuber clump with a pitchfork. Gently lift the entire clump from the ground and brush off excess soil. Allow the tubers to dry for a few days in a cool, dark location. Store the dried tubers in a container with a slightly moist medium such as peat moss or vermiculite. Ensure the storage area maintains a consistent temperature between 40°F and 50°F (4°C and 10°C) with good air circulation. Periodically check the tubers for signs of mold, rot, or excessive shriveling, adjusting moisture levels as needed.
Common Issues and Solutions
Dahlias can encounter pests and diseases. Slugs and snails feed on tender foliage. Keeping the soil surface dry and removing garden debris can deter them. Aphids and spider mites feed on plant sap. Insecticidal soaps or neem oil can help control these pests, and encouraging beneficial insects like ladybugs can provide natural predation.
Powdery mildew appears as a white growth on leaves and stems, especially in humid conditions. Ensuring adequate plant spacing for airflow and avoiding overhead watering can help prevent its spread. Removing affected leaves and using a baking soda spray or neem oil can be effective. Viral diseases, though less common, can cause leaf mottling, distortion, and stunted growth. There is no cure for viral diseases, so discard infected plants to prevent spread and disinfect tools between plants. Good garden hygiene contributes to healthier plants.
