Persicaria amplexicaulis

Red bistort does best with ample sunlight but can tolerate light shade. Its light requirements change during its life cycle, especially in the bud and flower phases when it needs abundant sun. It naturally occurs in sun-drenched habitats. Excessive sun can impede its growth, while insufficient light leads to poor flowering.

Red bistort grows well in many environments but especially prefers temperatures of 41 to 89.6 °F (5 to 32 ℃). During different seasons, the gardener must carefully monitor and adjust the temperature to keep it within this range for optimal growth.

The best time to fertilize Red bistort is in early spring, as it comes out of dormancy and starts active growth. Fertilizing supplies essential nutrients for healthy development. Although Red bistort has fairly low fertilizer requirements, an annual application can boost its survival and encourage improved, longer-lasting flowers.
