Planting A Hibiscus Hedge
Hibiscus hedges, like hibiscus specimen plants, prefer a sunny to semi-shady location sheltered from the wind. Hibiscus hedges prefer to grow in well-drained, nutrient-rich soil. A nutrient-poor soil can be enriched with humus-rich potting soil or compost.

You can either dig a separate planting hole for each plant or make a trench about 19″ deep along the entire length of the hedge. Then plant the plants and water them well.
