hardy hibiscus

Hardy hibiscus (Hibiscus 'Lester Riegel') should be watered regularly throughout the growing season. During the hottest months of summer, these shrubs may need to be watered 2 to 3 times per week. As the temperatures begin to cool off in the fall, you can reduce the frequency of watering to once a week. In the winter months, hibiscus may need very little or no supplemental watering. However, if the area where the hibiscus is planted experiences a milder winter, water once every 1 to 2 weeks to help keep the shrub healthy.

Hardy hibiscus (Hibiscus 'Lester Riegel') prefers a full sun location to stay healthy, bloom, and look its best. A minimum of 6 hours of direct, unfiltered sunlight is ideal. If possible, the plant should be located in a spot that receives all-day exposure, especially during the spring and summer months, when temperatures are warm and the plant is actively growing and blooming. In the winter, when the plant is dormant and very little flowering is occurring, a more shaded location may be tolerated.

Prune your Hardy Hibiscus (Hibiscus 'Lester Riegel') lightly in late winter or early spring just before new growth begins. Remove dead, diseased, or damaged stems as needed at any time during the growing season. Thin out overcrowded stems and remove any shoots that are growing outward from the main stem. To encourage bushier growth, cut off a few of the shoots just above a bud. Prune off faded flowers to prevent the plant from setting seed and to stimulate additional bloom. By pruning lightly and removing faded flowers, you'll enjoy an abundance of beautiful blossoms throughout the summer!
