hardy hibiscus

Hardy hibiscus needs to be watered thoroughly and regularly. During the growing season (spring through summer) water deeply and often enough to keep the soil consistently moist but not overly saturated. In general, they need an inch (2.5 cm) of water per week over the entire root zone. In particularly hot or dry weather, you may need to water your hibiscus more frequently. In the cooler fall months, as the plant is preparing to go dormant, allow the soil to dry out slightly between watering.

Hardy Hibiscus require full sun for at least 6-8 hours each day for best growth and flowering. The best time of day to provide full sun for this plant is in the morning and late afternoon, when the sun is less direct and the intensity lessens. This plant grows primarily during the spring and summer months, and it should receive full sun all day long during these times. In late fall and winter, partial shade is acceptable, but the plant should not be completely shaded.

For Hardy Hibiscus (Hibiscus moscheutos SUMMER SPICE BLEU BRULEE), pruning should be done in late winter or early spring, usually shortly before the new growth appears. Start by removing any dead, damaged, or diseased stems or branches. Cut the plant back by 1-third to 1-half of its overall height and width. This should remove any overcrowded stems or branches as well as thinning out the center of the plant to allow sunlight to reach its leaves. If you want to produce more flowers, prune the tips of the stems before they flower. Deadheading spent blooms is also recommended, as this will encourage more flowering. With a bit of diligence, hardy hibiscus can be maintained to its best health and appearance.
