Growth Stages

1

Establishment

2-4 weeks

New transplants settling in with emerging shoots and initial foliage growth

Water regularly to keep soil moist. Mulch around base to retain moisture. Avoid heavy pruning the first year.

2

Foliage Development

4-6 weeks

Spring and early summer growth with dramatic color changes from red-orange to golden-yellow foliage

Ensure full sun exposure for best color. Monitor for pests. Provide balanced fertilizer in spring if needed.

3

Flowering

4-6 weeks

Mid-summer appearance of delicate pink or rosy-pink flower clusters at branch tips

Flowers are self-sufficient. Continue regular watering. Deadhead spent flowers if desired to encourage extended blooming.

4

Summer to Fall Transition

6-8 weeks

Foliage transitions from golden-yellow to orange-red as temperatures cool; new growth may appear

Reduce watering slightly as growth slows. Avoid late-season high-nitrogen fertilizer which promotes tender growth.

5

Dormancy

3-4 months

Leaves drop in fall; plant enters winter rest period with bare stems

Prune in late winter before new growth. Remove any dead or damaged wood. Mulch to protect roots in cold zones.
