Something looks wrong?

Describe what you see on your morning gloryand we'll rank the likely causes — most likely first, least-invasive fix first.

Japanese beetles

Pestmoderate

Symptoms: leaves skeletonized between veins; lacy chewed foliage; metallic green-bronze beetles clustered on plants; feeding worst in warm midsummer sun

Spider mites

Pestmoderate

Symptoms: fine pale stippling/speckling on leaves; fine webbing on undersides in hot dry spells; leaves bronzing and dropping

  • CulturalHose down and raise humidity· every 3 days · ~2 wksstrong evidence — extension confidence

    Mites thrive in hot, dry, dusty conditions. Spray foliage (especially undersides) with water to dislodge them and reduce dust.

  • OrganicInsecticidal soap or horticultural oil - label use only· every 5 days · ~2 wksmoderate evidence — extension confidence

    Apply to undersides per label; mites resist many products, so soaps/oils are preferred. Not in extreme heat.

    Always follow the product label — it is the law.

Aphids

Pestlow

Symptoms: clusters of tiny soft-bodied insects on new growth and undersides; sticky honeydew or sooty mold; curled distorted new leaves; ants tending them

  • CulturalBlast off with water· every 3 days · ~2 wksstrong evidence — extension confidence

    Knock colonies off with a strong jet of water in the morning; repeat every few days. Light infestations rarely need more.

    For persistent colonies apply insecticidal soap to undersides per label. Avoid open flowers.

Leaf miners

Pestlow

Symptoms: winding pale tunnels inside the leaf; pale blotches between the upper and lower leaf surfaces; tunnels/blotches that can't be rubbed off because the larva is inside

  • CulturalPick mined leaves + row cover· every 5 days · ~3 wksmoderate evidence — extension confidence

    Remove and bag leaves with tunnels, and cover plants with insect netting to block the egg-laying flies. Damage is mostly cosmetic on leafy crops.
