Planting Hibiscus in Containers and Gardens

Overview

Every climate zone has a suitable hibiscus. Long bloom season, colors from white to carmine red. Northern gardeners grow in pots—outdoors in summer, indoors in winter. Rose of Sharon (H. syriacus) is widely hardy. Choose pot or ground, prepare, and plant.

Container Planting

Step 1: Pot Selection

Large container with drainage hole.

Step 2: Soil Mix

Potting soil + peat moss + vermiculite (1 cup per gallon of soil).

Step 3: Plant

Half-fill pot, loosen roots, set plant, fill to ¾ inch below rim.

Step 4: Site and Water

6–8 hours sun; water well.

Step 5: Fertilize

Frequent feeding with 7-2-7 (N-P-K) ratio.

In-Ground Planting

Step 1: Site Selection

Full sun; under eaves for wind/frost protection if possible.

Step 2: Spacing

Allow room per variety. Rose of Sharon needs 4–6 feet between plants.

Step 3: Soil Preparation

Dig hole larger than root ball. Mix in 1 shovel compost, peat moss, and 1 cup perlite/vermiculite for drainage.

Step 4: Plant and Water

Set plant, backfill, firm, water well.

Step 5: Fertilize Regularly

7-2-7 fertilizer; avoid excess nitrogen (promotes foliage over flowers).
