Crape Myrtle Bumpy Trunk, No Flowers: Gall, Planting Depth, or Shade

1.5-year-old crape myrtle (13+ ft) has bumpy trunks, didn't flower last year, not flowering yet, pale leaves, sparse canopy. Planted 6 inches above grade, full sun, watered during drought, dropped leaves early. Nursery says "needs root development," recommends Maxicrop and Epsom salt.

Bumpy Bark: Likely Gall

Wasp-induced galls—benign but unsightly. Rub smooth, spray neem oil on bark.

No Flowers: Critical Issues

Planting depth: 6 inches high = good.
Sun: Full sun = good.
Drought stress: Early leaf drop = stress = no flowers.
Lavender variety: Flowers later than others.
Root stimulator: Better than Maxicrop/Epsom salt for new trees.

Outlook

Should improve this year. Deadhead spent blooms to extend flowering. Few red leaves = fall color preview.
