Weeping Mulberry Decline: Scale and Webworms

One-Sided Dieback on Mature Mulberry

A 30-year-old weeping mulberry in Houston showed sudden leaf drooping and dry fruit on one side. The owner noted recurring webworms.

Diagnosis

Scale insects (white bumps on branches) are likely stressing the tree. The recommended "Atomic Grow" product claims to raise plant brix (sugar content), deterring pests by improving health.

Conventional Approach

Inspect branches for scale; apply horticultural oil in dormant season
Control webworms with Bt (Bacillus thuringiensis) or spinosad
Deep water during drought; mulch to conserve moisture
Consult an arborist for large, valuable trees
