Growing Perennial Hibiscus
Planting - Hibiscus can be planted from June until October and grows best in well-drained, organic-rich soils. They do best in full sun but can be planted in light shade, however, flowers will not be as vigorous. When planting, consider protecting it from windy areas. The stems are susceptible to breakage at ground level however in the right location, staking is not necessary. You will want to plant it with compost right at the soil line and water the plant with Fertlome Root Stimulator.
Watering - It is important not to over-water your hibiscus. During a dry spell, make sure you water well at least twice a week. Always check soil moisture before watering.
Fertilizing - Fertilize when growth begins and again in mid-summer with a granular organic slow-release fertilizer such as Espoma Flower Tone.
Deadheading and Trimming - Spent flowers will eventually fall to the ground, but dead-heading regularly will help the overall appearance of the plant. This year's growth should be left until the following spring. In the spring (beginning mid-May) or at the sign of new growth, cut your hibiscus back a few inches from the ground.
Winter Care - Hibiscus do die back to the ground in winter, so mulch the plant when the ground freezes.
One Last Tip: Do not cut back until spring! - Hibiscus are late to break, and often don’t show signs of growth until mid-June.
