Snowball Bush Crinkled Leaves: Insect Feeding and Organic Spray Options

Crinkled Leaves = Insect Damage

Crinkled, sick-looking leaves on snowball viburnum = sap-sucking insects (aphids, thrips, or leafhoppers) feeding on emerging foliage. Distortion happens as leaves expand around feeding sites.

Organic Treatment Options

Atomic Grow: Systemic—reaches insects inside curled leaves, cleans foliage, boosts plant health.
Pure Neem Oil (Dyna-Gro): Disrupts feeding/growth; spray early morning.
Insecticidal soap: Good contact kill; repeat weekly.

Why Viburnums Are Targets

They're insect magnets. Healthy plants tolerate some damage; stressed ones decline. Atomic Grow addresses both insects and stress.
