hardy hibiscus

Hardy hibiscus, or Hibiscus moscheutos 'Luna Red', should be watered deeply and regularly. During the plant's active growth it is best to keep the soil evenly moist but not soggy. Water plants slowly until water begins to seep through the drainage holes. Allow the excess water to drain completely, and then water again when the top of the soil feels dry to the touch. Make sure to check soil moisture often during hot, dry weather. During the dormant season the plant should be allowed to dry out somewhat between waterings, but it should not wilt. This species of hibiscus does best in soil that is slightly acidic. Fertilize monthly during the active growing season with a general purpose fertilizer.

Hardy hibiscus require at least 6 hours of direct sunlight per day to thrive and grow properly. The best time of day for a hardy hibiscus to receive sunlight is mid-morning to mid-afternoon when the sun is the strongest. During the summer months, when the days are longest, it is best to give the plant as much sunlight as possible. In the fall and winter, however, the days are shorter and the intensity of the sunlight is lower; giving the plant at least 6 hours of sun during these times is beneficial for successful growth.

Hardy hibiscus (Hibiscus moscheutos 'Luna Red') should be pruned in late winter, before it begins to produce new shoots in spring. Pruning this plant should be done lightly, only removing dead or invasive branches and old, woody stems, as hardy hibiscus blooms best on new growth. Care should be taken to leave plenty of stem and leaf growth. Thinning can be performed to reduce the plant’s size and shape it. Best practice is to prune no more than 1-third of the plant in any season. This will help your hardy hibiscus to become dense and full. With a little pruning each season, your hardy hibiscus will reward you with beautiful blooms throughout the summer.
