How to Plant a Hibiscus Syriacus Paeonyflorus

Overview

Hibiscus syriacus paeonyflorus, also known as rose of Sharon, is a vigorous perennial shrub native to Asia. Its cup-shaped flowers grow up to 3 inches in diameter and bloom from late summer through fall in blues, pinks and purples. This particular hibiscus reaches heights from 8- to 12-feet tall and is a low maintenance bush perfect for growing into a hedge, or using as a background shrub in the landscape.

Step 1

Select a location that receives full sun daily with perhaps light shade in the afternoon. Prepare the site in early spring as soon as the soil is workable.

Step 2

Till or rake the dirt to loosen up down to 1-foot depth. Hibiscus needs a well-draining soil, so amend with compost if you have heavy, clay soil.

Step 3

Dig a hole that is only as deep as the root ball and two times as wide. If planting more than one shrub, space the plants about six to 10 feet apart.

Step 4

Set the hibiscus shrub in the hole so the top of the root ball is level with the ground's surface. Fill in the hole halfway with the soil; water well to settle the soil and eliminate any air pockets that can form around the roots. Let the water drain out all of the way, then fill in the hole the rest of the way with soil. Tamp down well around the base of the plant.

Step 5

Water your shrub well after planting so the soil is thoroughly saturated. Use a soaker hose or a garden hose with the water running at a trickle. Water on a regular basis one to two times weekly, letting the soil dry out in between watering. During the summer months only water if there is less than 1 inch of rainfall.

Step 6

Feed your hibiscus shrub after planting with an all-purpose fertilizer made for flowering shrubs (e.g., 10-10-10). Each season fertilize once a year in late spring after the last frost. Use a water-soluble food for best results.

Step 7

Add a 2-inch layer of mulch that extends out to the drip line or the outermost branches. This helps to retain moisture and control weeds. Use chopped leaves, pine needles or shredded bark.
