Growth Stages

1

Establishment

3-6 months

Newly planted shrub with initial root development and foliage settling. Growth is minimal in first year.

Water regularly to establish roots. Avoid fertilizing first year. Mulch around base 2-3 inches deep, keeping clear of stem.

2

Vegetative Growth

Spring through early summer, ongoing yearly

Shrub develops dense, glossy dark green foliage in a compact mounding form. Slow, steady growth occurs during spring and early summer.

Apply balanced, slow-release fertilizer in spring. Prune lightly after flowering to maintain shape. Remove dead or damaged wood.

3

Flowering

March-April (3-4 weeks)

Dense panicles of small, fragrant white to pale pink flowers appear at branch tips. Male and female flowers occur on separate plants.

Ensure both male and female plants present for berry production. Do not deadhead if berries are desired. Enjoy fragrance, especially in late afternoon.

4

Fruiting & Berry Development

May through February of following year

Fertilized female flowers develop into clusters of bright red, glossy berries that persist on branches through winter. Berries are highly ornamental.

Maintain consistent moisture during fruit development. Apply slow-release fertilizer in early summer. Protect from harsh winter winds.

5

Winter Rest

December-February

Foliage darkens slightly in cold; plant remains evergreen. Bright red berries provide winter ornamental interest.

Reduce watering but do not allow soil to dry completely. Provide windbreak in exposed locations. Avoid pruning during dormancy.
