Hibiscus 'Sweet Caroline'

Hardy hibiscus (Hibiscus 'Sweet Caroline') is a deciduous flowering plant that is easy to grow and tolerant of a range of soils, just as long as it is well-drained. It features large, fragrant flowers that are pinkish-red with a yellow center and dark green leaves. Reaching heights up to 8 feet, it blooms from mid-summer until early fall. It does best in full sun and doesn't need much fertilizer. Plant in groups for a stunning display. Hardy Hibiscus is a great choice for adding a pop of color to any garden.

watering

Hibiscus 'Sweet Caroline' requires regular watering, so it's important to keep the soil moist but not soggy. During the spring and summer when the plants are actively growing, water your hibiscus deeply about once per week while allowing the top 2 inches of soil to dry out in between each watering. During periods of drought, water your hibiscus every 3 to 4 days. During winter or periods of dormancy, water your hibiscus deeply about once every 2 weeks. Always use lukewarm water when irrigating hibiscus, as cold water can shock the delicate root system.

sunlight

Hardy hibiscus (Hibiscus 'Sweet Caroline') prefers a full sun location where the plant can receive 6-8 hours of direct sunlight daily in order to thrive and flower optimally. It is important that this hibiscus is planted in an area with full sun exposure; otherwise, it may display signs of leaf yellowing, slow growth, or failure to bloom.

pruning

Hardy hibiscus generally requires light pruning in late winter or early spring. This helps to keep the plant in good shape and to prevent overgrowth. Start by removing dead and diseased stems, followed by any branches that cross over or rub against each other. These can cause damage and increase the risk of disease or pests. Then, thin out any dense foliage to improve air circulation and light penetration. Lastly, cut back a few of the larger, more mature stems to the desired shape and size. This will encourage bushy new growth and will prevent the plant from becoming overgrown. Avoid pruning too heavily or too late in the season, as this can interfere with or weaken future blooms.
