What's eating my giant sequoia 'blauer eichzwerg'?

'Blauer Eichzwerg' is a slow-growing dwarf blue-green sequoia. Because it stays compact, deer and rabbits can browse the whole plant for years, making them the chief threat in gardens. Sequoia pitch moths and spider mites also pose risks, and bagworms occasionally target the dense foliage in drier regions.

Browsed shoot tips and stripped branches across the entire plant due to its low, accessible height Surround with a wire cage until the plant reaches a height that deters casual grazing; use repellent sprays as supplementary deterrents

Resin masses oozing from stems, indicating larval boring in bark tissue Maintain plant vigor with adequate water and avoid wounding bark; remove pitch masses mechanically before adult moths emerge in late spring

Bronzed, stippled needles and fine webbing during summer heat and drought Water regularly to avoid drought stress; apply horticultural oil or insecticidal soap spray to the dense compact foliage in early summer
