Hibiscus Summerific ‘Candy Crush’ is a vibrant perennial known for its dramatic visual appeal. It thrives in various settings, offering an impressive seasonal display.
Unique Characteristics of ‘Candy Crush’
Its large blooms, up to 8 inches in diameter, are vibrant bubblegum-pink with a deep red eye. Ruffled petals add unique texture.
It reaches 3 to 4 feet tall and wide. Its vigorous, upright growth forms a dense bush. It blooms from mid-summer into fall and is hardy in USDA Zones 4 through 9.
Planting and Ongoing Care
Select a site with full sun, meaning at least six hours of direct sunlight daily. Well-draining soil prevents root issues. Enriching the soil with organic matter before planting improves its structure and fertility.
When planting, dig a hole twice as wide and deep as the root ball. Place the plant, ensuring the root ball top is level with the soil. Backfill with amended soil, firming it around roots to remove air pockets. Water thoroughly after planting to settle soil.
Consistent moisture is needed for ‘Candy Crush’ establishment and health. During its first growing season, maintain evenly moist soil, especially during dry spells. Mature plants need regular watering, particularly when rainfall is insufficient, to support robust growth and prolific blooming.
For vigorous growth and blooms, fertilize ‘Candy Crush’ in early spring as new growth emerges. Apply a balanced, slow-release granular or liquid fertilizer for flowering plants. Avoid excessive nitrogen, which promotes foliage at the expense of blooms.
Prune in late winter or early spring before new growth. Remove dead or damaged stems, and prune to shape or control size. Cutting stems by one-third encourages bushier growth and more prolific flowering.
Addressing Common Problems
‘Candy Crush’ can encounter pests. Aphids, which cluster on new growth, can be dislodged with a strong water spray or insecticidal soap. Japanese beetles feed on foliage and flowers; hand-picking them in the morning helps manage their population.
Fungal diseases like leaf spot or powdery mildew may appear in humid conditions or with poor air circulation. Adequate spacing and watering at the base (not overhead) help prevent these issues. Fungicides can be applied if an outbreak becomes severe.
Plant health can be impacted by environmental factors. Insufficient sunlight causes a lack of blooms; ensure full sun for prolific flowering. Yellowing leaves indicate overwatering or nutrient deficiencies; check soil moisture and fertilize appropriately. Addressing these issues maintains plant vigor.
Preparing for Winter
To ensure its return in spring, prepare ‘Candy Crush’ for winter. After the first hard frost, when foliage dies back, cut stems down to 4 to 6 inches above the ground. This conserves energy for the next growing cycle.
In colder zones, apply a 3 to 4-inch layer of organic mulch, such as shredded bark or straw, around the plant’s base. This insulates roots, stabilizes soil temperatures, and prevents damaging freeze-thaw cycles.
Hardy hibiscus are among the last perennials to emerge in spring, often not showing new growth until late May or early June. This is a normal part of their dormancy cycle. Do not assume the plant has died if it is slow to reappear.
