Dahlias bring vibrant beauty to any garden, and the ‘April Heather’ variety stands out with its unique charm and appeal. Understanding its specific needs helps cultivators enjoy its striking presence throughout the growing season.
What is April Heather Dahlia
‘April Heather’ is a Collerette dahlia, characterized by a single outer ring of overlapping ray florets and a central disc encircled by a collar of smaller florets. Its blooms measure 3 to 5 inches in diameter. The flower presents a delicate blend of colors: soft apricot pink outer petals, a pale yellow collar, and a golden-yellow center. Colors transition to pink or beige as they mature, and petals are long-lasting. ‘April Heather’ plants reach a height of 3 to 5 feet. This dahlia blooms from mid-summer until the first autumn frost.
Growing April Heather Dahlia
‘April Heather’ dahlias thrive in locations receiving ample sunlight, ideally six to eight hours of direct sun, especially morning sun. Protect from strong winds to prevent stem and bloom damage. They flourish in rich, well-draining soil (pH 6.0-7.5). Before planting, loosen soil to 12 inches and amend heavy clay with organic materials like aged manure, compost, or peat moss for drainage and aeration.
Plant ‘April Heather’ dahlia tubers in spring after the last frost, when soil temperature reaches 60°F (15°C). This usually coincides with when tomatoes are planted outdoors in your region. Dig a 4 to 8-inch deep hole and place the tuber horizontally with the “eye” facing upwards. Cover with 2 to 6 inches of soil, avoiding immediate watering until shoots emerge to prevent rot. Space tubers 12 to 18 inches apart for air circulation and growth.
Once sprouts emerge and plants reach 8 to 12 inches tall, consistent watering is important. Aim for one inch of water per week, or water deeply two to three times weekly, more in hot, dry climates. Water at the base to keep foliage dry, preventing fungal diseases like powdery mildew. Check the top 2-3 inches of soil for dryness before watering to ensure adequate moisture without waterlogging.
Fertilize ‘April Heather’ dahlias for vigorous growth and abundant blooms. Use a low-nitrogen fertilizer (e.g., 5-10-10), often called bloom food. Apply first 30 days after planting, then every three to four weeks throughout the growing season. Cease fertilization by late August to allow tubers to mature for winter storage.
Pinching the central stem of young dahlias encourages bushier growth and increases flower production. When 10 to 12 inches tall with at least four leaf sets, pinch off the top 3 to 4 inches of the main stem. As ‘April Heather’ grows tall, staking is recommended to support and prevent stems from breaking, especially in windy conditions. Install sturdy stakes (wood or steel T-posts) 3 inches from the plant at planting, pushing them 12 inches deep. Tie stems loosely to stakes as the plant grows, allowing natural movement.
Maintain healthy ‘April Heather’ dahlias by managing pests and diseases. Common pests include slugs, snails, aphids, thrips, spider mites, and earwigs. Control methods include handpicking larger pests, using insecticidal soaps or neem oil for soft-bodied insects, and introducing beneficial insects like ladybugs. For slugs and snails, barriers like copper tape or diatomaceous earth can be effective. Regularly inspect plants and promptly remove diseased foliage to limit spread of issues like powdery mildew.
In colder climates (USDA Zones 7 and below), ‘April Heather’ dahlia tubers are sensitive to freezing temperatures, requiring lifting and indoor storage for winter. After the first hard frost blackens foliage, cut stems back to a few inches above ground. Carefully dig up tubers, avoiding damage, and clean off excess soil. Air dry for several days to weeks in a cool, dark, well-ventilated area away from direct sunlight, then store in a frost-free environment (40-50°F / 4.4-10°C). Nestled in peat moss, vermiculite, or wood shavings in cardboard boxes or paper bags, ensure good air circulation and periodically check for signs of rot or shriveling.
Displaying and Enjoying April Heather Dahlia
‘April Heather’ dahlias are favored for cut flower arrangements due to their appealing, lasting blooms and unique soft apricot pink, pale yellow, and creamy coloration, suitable for wedding designs. When harvesting, cut stems in the morning when flowers are nearly or fully open, as buds generally do not unfurl much after cutting. Remove foliage below the waterline to maintain water cleanliness. In cool water and out of direct sunlight, cut ‘April Heather’ dahlias last five to seven days. Regularly deadhead spent blooms to encourage new flowers and extend the blooming period.
