Growth Stages

1

Establishment

First 12 months

Young plant with developing root system and sparse branching

Water regularly to establish roots. Avoid heavy pruning first year. Mulch to retain moisture.

2

Vegetative Growth

Year 2-3

Plant develops dense, graceful branching habit with fine, narrow green leaves

Prune lightly after flowering to maintain shape. Fertilize in spring with balanced fertilizer.

3

Pre-flowering

Late winter to early spring

Branch tips thicken and develop flower buds in late winter

Do not prune during this period to avoid removing flower buds. Reduce nitrogen fertilizer.

Enjoy the blooms; deadhead spent flowers if desired. Light pruning can be done immediately after flowering.
