Growth Stages

1

Establishment

First 12 months

Young plant with developing root system and initial branching structure

Water consistently during first growing season (1-2 inches weekly); stake if windy; apply 2-3 inches of mulch around base, keeping away from stem

2

Vegetative Growth

Months 3-12 (year 1-2)

Plant develops strong branching framework with glossy green leaves; no flowers yet or minimal blooms

Light pruning to shape; ensure good air circulation; fertilize in spring with balanced or low-nitrogen fertilizer; reduce fertilizing by mid-summer

3

Flowering

June-September (3-4 months)

Abundant red-orange panicles (flower clusters) appear at branch tips; blooms attract pollinators and hummingbirds

Deadhead spent blooms to encourage continuous flowering; avoid heavy pruning during bloom season; water during drought to support flowering

4

Fall/Winter Dormancy

October-February (5 months)

Leaves turn red or purple before dropping; exfoliating bark becomes prominent; bare branches remain attractive

Cease fertilizing; reduce watering significantly; do not prune heavily (save major pruning for late winter/early spring); clean up fallen leaves

5

Early Spring Growth

February-April

New red or bronze foliage emerges; late winter pruning is optimal; leaf-out accelerates

Perform major pruning in late February-March before new growth; remove crossing branches, dead wood, and seed pods; resume regular watering as growth increases

Companion Planting

Plant with:

Avoid planting near:

Black Walnut (Juglans nigra) - allelopathic toxin Heavily competing root systems (large oaks) Areas with poor drainage or standing water

Common Pests

  • Prune and destroy heavily infested branches; spray horticultural oil in late winter or dormant oil in early spring; repeat applications may be needed; use insecticidal soap during growing season

  • Ensure good air circulation through pruning; avoid overhead watering; spray with sulfur or neem oil at first signs; Tonto has improved resistance compared to older cultivars

  • Spray with strong water stream to dislodge; use insecticidal soap or neem oil; encourage natural predators like ladybugs

  • Handpick in early morning; use Japanese beetle traps away from plant; apply neem oil or spinosad if severe
