Planting the Swamp Rose Mallow
When planting the Swamp Rose Mallow, it is essential to choose a location with full sun to partial shade. The plant prefers moist to wet soils, making it an ideal choice for gardens with poor drainage or areas near ponds or lakes. Plant the Swamp Rose Mallow in the spring or fall, when the weather is cooler, to minimize transplant shock. Dig a hole that is twice as wide and just as deep as the plant’s root ball, and add organic matter such as compost or manure to improve soil fertility and drainage.

The Swamp Rose Mallow prefers slightly acidic to neutral soils with a pH between 6.0 and 7.0. The soil should be rich in organic matter and have good drainage to prevent root rot. If your soil is heavy clay or sandy, mix in organic matter such as compost or well-rotted manure to improve its structure and fertility. The following table provides a summary of the ideal soil conditions for the Swamp Rose Mallow:
| Soil Characteristic | Ideal Value |
|---|---|
| pH | 6.0-7.0 |
