Petal drop is not the same problem as a blocked stem. If heads are also bending, use the droop diagnosis; if nearby fruit may be involved, apply the fruit-exposure check before returning the vase to the same spot.

The useful clue is distribution: one flower, one side of the bouquet or the whole arrangement. Record what changed during the previous day before resetting everything.

Read the distribution

Three petal-drop patterns

Groom

One mature flower

Dry petals release from a fully open bloom while neighbouring flowers stay firm.

Investigate

Several flowers at once

Look for ripe fruit, vehicle exhaust, smoke, heat or a recent transport event.

Isolate

Soft spotted petals

Wet, translucent or fuzzy tissue should not remain pressed against healthy blooms.

The five-minute check

  1. 01
    Lift fallen petals with dry paper

    Note whether they are dry and intact, bruised at the edge or wet and marked.

  2. 02
    Turn the flower gently

    Check whether loss is even or concentrated where blooms rubbed a sleeve, wall or another head.

  3. 03
    Inspect the flower base

    A clean release from a mature bloom differs from tissue that is brown and collapsing around the attachment.

  4. 04
    Compare every species

    If only one sensitive flower type drops, a bouquet-wide water reset may not be the answer.

Match the action to the cause

Likely causeEvidenceAction
Normal ageingOldest, most open flower onlyRemove that bloom and keep sound stems
Handling damageLoss on the contact side; creased petalsGive heads more space and stop repeated rearranging
Ethylene exposureRapid loss across sensitive flowers after fruit or exhaust exposureMove to clean air; remove the source
Moisture diseaseSoft spotting, fuzz or spread between touching petalsBag and discard affected material; clean the vase area

Watch the next 24 hours

After removing affected blooms and moving the vase, place a clean sheet of paper beneath it. New petal fall shows whether the event is continuing. If several flowers keep shedding despite a stable cool location, enjoy or preserve the remaining sound material rather than applying repeated revival tricks.
