hardy hibiscus

The Hardy Hibiscus (Hibiscus 'Kopper King') is a low-maintenance flowering perennial that requires regular watering when in bloom during hot or dry periods. For best results, water 1-2 times per week when temperatures are high and reduce the amount during the cooler months or when temperatures drop below 70°F (21°C). Water deeply and avoid over-watering which can cause root rot. Ensure that the soil is well-draining and allow the top 2 inches of soil to dry out between waterings. In the summer, provide your plant with additional water by giving it a deep soak every few weeks.

Hardy hibiscus (Hibiscus 'Kopper King') will require 6 to 8 hours of direct sunlight each day for optimal growth. If the plant is in a container, it may need more sun, as the roots can absorb heat from the container and create a zone of warmer air around the plant. This plant will also grow and flower best when planted in areas where the soil is consistently moist. Planting in soil that drains well will help keep the plant from becoming over-watered. In colder climates, the hibiscus will benefit from protection from strong winds and will need to be examined regularly for frost damage.

Hardy hibiscus (Hibiscus 'Kopper King') requires regular pruning throughout the growing season. The best time to prune hardy hibiscus is in late winter to early spring. This pruning should involve removing any winter damage and dead blooms - as well as shaping the plant to how you'd like it. To encourage new growth and encourage blooms, midsummer pruning can be done as well. Remove any stems that appear dead or damaged, as well as any that have flowered - this will help promote more blooms during the remainder of the bloom season.
