watering

Hardy hibiscus (Hibiscus 'Summer Storm') enjoys consistent watering during the summer months. Water deeply at least once a week during active growth, and slightly reduce watering frequency during fall and winter months. Be sure to check the soil before watering - if it is still moist, wait before adding more water. Always keep the soil evenly moist but not wet or soggy. If the plant fails to receive adequate water, it may experience wilting.

sunlight

Hardy Hibiscus (Hibiscus 'Summer Storm') should receive plenty of bright, direct sunlight. This plant species likes full or partial sun, meaning they require about 6 to 8 hours of sunlight each day. Ideally, the plant should be placed in an area of the garden that receives the morning sun and partial afternoon shade. During the summer months, Hardy Hibiscus should be protected from intense midday sunlight to avoid damage and wilting of the blooms. In addition, during periods of extreme heat, some afternoon shade can help protect the plant from sunburn or other damage.

pruning

Hardy hibiscus (Hibiscus 'Summer Storm') requires minimal pruning to maintain its shape and vigor. Pruning should typically be done once in the late summer or early fall; however, an additional pruning may be done if needed in late winter or early spring. Prune the hardy hibiscus to a height of 3 feet or slightly above. For beds or hedges, prune sides to create a bushier plant and encourage healthy growth. Remove any dead, diseased and crossing branches as well as stems that appear weak or have little flowering potential. Smaller stems of hibiscus should be jammed in or near the base of the plant. When pruning, make sure that the tool or scissors used are clean and sharp.
