Care Guide
Planting
Plant Dotted Smartweed in full sun during spring or early summer when the soil can stay consistently moist. This native perennial thrives in wet habitats and shallow water areas, so choose a location near a pond edge, rain garden, or other area that stays boggy - it's not suitable for dry garden beds. Space plants about 2–3 feet apart since they grow moderately fast and reach up to 3 feet tall.
After Planting
Water consistently to keep soil wet or moist throughout the growing season; this plant actively grows during summer and requires reliable moisture. Expect it to die back in fall as a deciduous perennial, which is normal. Be aware that Dotted Smartweed is short-lived, so plan to replace it every few years or allow it to self-seed in your wet garden area.
