What's Eating My Roses?
Roses collect admirers of every species. Most damage traces to five suspects — and one of them is a bee you should thank rather than fight.
The usual suspects
Japanese beetles
The signs: Blooms shredded from the inside out and leaves skeletonized, in daylight, beetles in flagrante.
What it looks like: Metallic green-and-copper, arriving in waves from late June.
What to do: Morning knock-downs into soapy water; in peak weeks, cut prized buds for the vase before they open outside. Skip beetle traps near the garden — they recruit.
Rose slugs (sawfly larvae)
The signs: Leaves windowpaned to translucent patches in spring, then skeletonized to lace from below.
What it looks like: Small pale-green slug-like larvae on leaf undersides — not true slugs; no slime.
What to do: Flip leaves and squish or soap-spray on contact; they're spring-concentrated, and plants regrow clean by summer.
Aphids
The signs: Buds and new shoots crusted with colonies, sticky honeydew, sooty smudges.
What it looks like: Green or pink soft-bodied insects packed on the tenderest growth.
What to do: Blast every few days for a week; the ladybug cavalry usually arrives right behind the outbreak.
Thrips
The signs: Buds that ball and brown without opening; petal edges bruised and streaked, worst on pale varieties.
What it looks like: Slivers of insects deep in the petals — shake a bloom over paper to see them.
What to do: Deadhead and trash damaged blooms, keep plants watered, and blue sticky cards nearby; sprays reach them poorly inside the bud.
Spider mites
The signs: Stippled bronzing foliage and fine webbing in hot dry spells.
What it looks like: Paper tap-test tells.
What to do: Hose the undersides routinely in drought; oil or soap for flare-ups.
Deer
The signs: Buds and shoots bitten off ragged, head-high, thorns notwithstanding.
What it looks like: Rose buds are deer candy; damage is nightly and repeat.
What to do: Repellent rotation helps; fencing or a fenced cutting bed is the only guarantee.
Leafcutter bees
The signs: Perfect half-moon circles scalloped from leaf edges — tidy as a paper punch.
What it looks like: A gentle native bee lining her nest with the discs.
What to do: None. The damage is cosmetic, the pollinator is precious; consider it a signature, not a wound.
When it's not a pest at all
Black spots with fringed edges on yellowing leaves are black spot fungus, roses' oldest enemy — water at the base, prune for air, choose resistant varieties. White powder on buds and leaves is powdery mildew.
