What's Eating My Hydrangeas?

Hydrangea damage is usually more alarming than fatal — these shrubs regrow generously. Sort the deer from the insects by the size of what's missing.

Deer

The signs: Buds, blooms, and shoot tips bitten off ragged overnight — often precisely the flower buds you waited all year for.

What it looks like: Browse height, torn (not cut) stems, and hoofprints; damage repeats nightly in season.

What to do: Repellents rotated from bud set onward, netting over prize shrubs in spring, fencing where deer pressure is chronic. Bloom loss isn't plant death — the shrub itself shrugs it off.

Japanese beetles

The signs: Leaves lacy-skeletonized and petals shredded midsummer, beetles present in daylight.

What it looks like: Oakleaf and panicle types attract them most.

What to do: Morning knock-downs into soapy water; established shrubs tolerate cosmetic loss.

Aphids

The signs: Sticky curled new growth and sooty mold on leaves below.

What it looks like: Soft green colonies at stem tips in spring.

What to do: Water-blast the tips a few mornings running; beneficials do the rest.

Slugs

The signs: Ragged holes in low leaves on young plants, slime traces at dawn.

What it looks like: Night feeders in moist mulched beds — hydrangea country.

What to do: Morning watering and iron phosphate around new plantings.

Spider mites

The signs: Stippled bronzing leaves in hot dry corners, fine webbing beneath.

What it looks like: Tap-test over paper.

What to do: Shower foliage in dry spells; soap for outbreaks.

When it's not a pest at all

A hydrangea that leafs out but never blooms wasn't eaten — it was pruned at the wrong time or lost buds to a cold snap (the classic bigleaf-hydrangea heartbreak). Brown-edged leaves in August sun are scorch; move the water, not the blame.
