Planting instructions
Plant Fizzy Mizzy Sweetspire in full sun to full shade with well-draining soil. Dig a hole approximately twice as wide as the rootball and no deeper than the rootball itself. Position the plant level with or slightly above the surrounding soil, backfill with native soil, water thoroughly, and apply a 2–3 inch layer of mulch while keeping it several inches away from the stems.
Watering & sunlight
Water deeply when the top 2–3 inches of soil begin to dry. During establishment, this is typically once or twice per week, keeping the soil evenly moist but not soggy. Once established, Sweetspire is moderately drought tolerant but performs best with consistent moisture. Watering frequency will vary depending on climate, soil type, rainfall, sunlight exposure, and establishment phase.

Fizzy Mizzy Sweetspire performs well in full sun, part sun, part shade, or full shade. While it flowers well even in shade, plants grown with a few hours of sunlight each day typically produce the heaviest bloom display and best fall color.
Care guide

PRUNING
Prune only if needed immediately after flowering. Fizzy Mizzy blooms on old wood, so pruning later in the season may remove next year's flower buds. Little pruning is generally needed thanks to its naturally tidy, compact habit.

FERTILIZING
Apply a balanced slow-release fertilizer in early spring if desired. Avoid fertilizing for the first 2–3 months after delivery to allow the plant to adjust and establish.

WINTER PROTECTION
Fizzy Mizzy Sweetspire is cold hardy throughout its growing range. Apply mulch around the base during the first winter to help conserve moisture and protect the roots.
