Planting & Care

The Summerific® 'Valentine's Crush' Rose Mallow is a vibrant and robust perennial that requires specific care to thrive and bloom to its full potential. Here's how to plant and care for this stunning garden addition:

Planting Instructions:

  1. Timing: The best time to plant 'Valentine's Crush' is in the spring after the danger of frost has passed, or in early fall to allow it to establish before winter.
  2. Location: Choose a location that receives part sun to full sun (4-6 hours of direct sunlight minimum). This plant loves the sun and will produce more blooms in a brighter spot.
  3. Soil Preparation: Hibiscus prefers moist, well-drained soil. Amend heavy clay or sandy soils with compost or peat moss to improve soil structure and water retention.
  4. Planting: Dig a hole twice as wide and just as deep as the root ball. Remove the plant from its container, gently loosen the roots, and place it in the hole. Backfill with soil, pressing down firmly to eliminate air pockets. Water thoroughly.

Care Instructions:

  1. Watering: Keep the soil consistently moist, especially during the first growing season to establish a deep, extensive root system. Once established, the plant can tolerate occasional dry spells, but regular watering will promote optimal growth and flowering.
  2. Mulching: Apply a layer of mulch around the base of the plant to retain soil moisture, regulate soil temperature, and reduce weed competition.
  3. Fertilizing: Feed your 'Valentine's Crush' in early spring with a balanced, slow-release fertilizer to support vigorous growth and blooming. Follow up with additional feedings every few months during the growing season, as recommended by the fertilizer instructions.
  4. Pruning: Hibiscus is a perennial that will die back in the winter. In late winter or early spring, before new growth starts, cut back any remaining stems to about 4-6 inches from the ground. This encourages fresh, healthy growth and more blooms.
  5. Winter Care: In colder zones (4-5), apply a thicker layer of mulch after the ground freezes to protect the roots. In spring, remove the extra mulch to allow new shoots to emerge.
  6. Pest and Disease Management: 'Valentine's Crush' is relatively disease-resistant but watch for common pests like Japanese beetles. Practice good hygiene by removing any fallen debris and spent flowers to minimize disease risks.
  7. Patience is Key: Remember, Hibiscus can be one of the last perennials to emerge in spring. Don't worry if it seems slow to start; its vigorous growth later in the season will compensate for the late emergence.

By following these planting and care guidelines, your Summerific® 'Valentine's Crush' Rose Mallow will become a stunning feature in your garden, offering bright, showy blooms and attracting hummingbirds and other pollinators throughout its flowering season.
