Growth Stages

1

Establishment

6-12 months

Young plant focuses on developing root system and establishing growth habit

Keep soil consistently moist without waterlogging. Provide shelter from harsh winds. Light pruning to encourage bushiness. Mulch with peat or pine bark.

2

Vegetative Growth

12-24 months

Plant develops dense, low mounding form with fine, needle-like foliage

Continue regular watering. Light deadheading of spent flowers encourages fuller growth. Mulch annually to maintain acidity and moisture.

3

Flowering

June-September (3-4 months)

Produces clusters of delicate, urn-shaped flowers in shades of pink, red, or white, typically at branch tips

Flowers appear in summer and continue into fall. Maintain consistent moisture during flowering period. Deadhead spent flowers to extend blooming.

4

Dormancy

December-February (2-3 months)

Plant enters winter rest period; foliage may take on bronze or reddish tones

Reduce watering but maintain some soil moisture. Provide winter protection in zones 5-6 with evergreen boughs or burlap. Avoid pruning in late fall.
