How to Plant Pink Hardy Hibiscus


Pink hardy hibiscus (Hibiscus moscheutos), also known as Kopper King, is native to marshy areas in North America. This perennial is hardy as far north as USDA Hardiness Zone 3 and as far south as zone 9. The hardy hibiscus plant is a nontropical variety, meaning it is hardier than other varieties and very prolific, producing more than 100 blooms per season. The pink flowers range from 3 to 12 inches in diameter and start blooming in late May or early June and continue through the first frost. This fast-growing, hardy plant is a good choice for a novice gardener.

Step 1

Select an area that receives full sun for at least six hours daily to plant your hibiscus. Plant in late spring or early summer for best results.

Step 2

Work the ground in late spring, after the last frost, to loosen the soil. Use a rake, or a small rototiller if necessary, to work in nutrient-rich soil if you have heavy, clay soil.

Step 3

Dig a hole that is twice as deep and wide as the root ball. Place the plant in the hole with the top of the root ball level with the ground's surface. Fill in with soil and tamp down firmly around the base of the plant.

Step 4

Water the hibiscus well after planting, using a soaker hose or drip irrigator. Keep your plant watered consistently every two to three days just so the soil stays moist but not soaking.

Step 5

Fertilize with a high-phosphorus fertilizer, such as 5-10-5, to ensure plenty of blooms throughout the season. Phosphorus is the middle number on the fertilizer bag; nitrogen is the first number; and potassium is the last number. Too much nitrogen encourages more foliage growth and fewer blooms.

Step 6

Mulch around your hibiscus to help control weeds, to maintain moisture in the soil and to protect the roots from colder conditions during winter. Shredded bark, pine needles or chopped leaves can all be used as mulch.
