Planting instructions
Choose a planting location with full sun and well-draining soil. Dig a hole two to three times wider than the root ball and about the same depth as the nursery container so the tree sits at the same level it was growing previously. Place the tree in the hole, backfill with soil, and gently firm the soil to remove air pockets. Water thoroughly after planting. Apply 2–3 inches of mulch around the base of the tree to retain moisture and regulate soil temperature, keeping mulch a few inches away from the trunk.
Watering & sunlight
Watering needs are never one-size-fits-all. Weather, soil type, drainage, plant size, and planting time all affect how quickly a plant dries out.

Use a slow-running hose, soaker hose, or drip system to water the root ball and surrounding root zone thoroughly. Allow the water to penetrate deeply (not just wet the top few inches of soil), and avoid frequent, shallow watering.

Before watering again, check the soil 3–4 inches deep near the root ball. If it feels dry, repeat this deep-watering process. If it feels moist or soggy, wait and check again in 1–2 days. Check the soil of newly planted trees and shrubs several times per week, especially during hot, dry, or windy weather.

Irrigation run times will vary based on flow rate, soil, and system setup.

Thunderstruck™ White Lightning™ Crape Myrtle grows best in full sun, which encourages abundant flowering and maintains the deep foliage color.
Care guide

PRUNING:
Prune in late winter or early spring while the tree is dormant to remove dead or crossing branches and shape the canopy. Minimal pruning is usually needed.

FERTILIZING:
Apply a balanced slow-release fertilizer in early spring to promote healthy growth and strong flowering. Avoid fertilizing for the first 2–3 months after delivery to allow the plant to adjust and establish.

WINTER PROTECTION:
Within its recommended growing zones, this crape myrtle typically requires no special winter protection. Mulching around the base of young trees can help regulate soil moisture and temperature.
