This species thrives in any well-drained soil, making it versatile for various garden settings. To plant, dig a hole that comfortably fits the root ball, position the plant ensuring the top of the root ball is level with the soil surface, and backfill with the excavated soil. Firm the soil around the base and water thoroughly. Space the plants adequately to allow for their upright to bushy growth, reaching up to 1.2 meters in height. Regular watering is essential, especially during dry spells, to maintain its lush, green foliage and vibrant red blooms throughout the flowering season.

Pruning a Persicaria amplexicaulis 'Speciosa'

A balanced, slow-release fertilizer is optimal, providing a steady supply of nutrients without overwhelming the plant. It's important to apply the fertilizer to the soil around the base of the plant, ensuring it's well-integrated and avoiding direct contact with the foliage to prevent any potential damage. This method will enrich the well-drained soil it favors, bolstering the plant's health and enhancing its ornamental appeal throughout its active growth phases.
