Pseudolarix amabilis pests — FAQ
What is eating my pseudolarix amabilis?
Pseudolarix amabilis (Golden Larch) is largely pest-free but shares some conifer vulnerabilities. Woolly aphids can colonise new growth; adelgids produce waxy tufts at bud bases. Deer browse soft new foliage in spring. Squirrels may take cones. Healthy, well-drained specimens are rarely seriously damaged — soil drainage matters more than pest control.
