   Blackened, translucent or limp tissue appearing suddenly after a cold night or a spell beside a draught. Tender plants show it well above freezing — basil blackens around 10 °C — so 'there has been no frost' does not rule it out.

   Points towards it

   • · the buds browned within days of a frost, which is how quickly this happens
   • · the damage is worst on the side that catches early morning sun, because rapid thawing does more harm than the freeze
   • · an outdoor exposure problem

   Argues against it

   • · no cold event points instead at the previous summer's watering, which decides bud numbers rather than bud survival

   Check this next

   Look at which side of the plant lost its buds and what faces east. Frost-and-thaw damage is markedly one-sided on a plant catching early sun; buds lost for any other reason come off all round the plant evenly.

   What to do now

   Move a container-grown camellia away from an east-facing position, or plant new ones where the morning sun does not reach them. The plant itself is undamaged and the buds cannot be saved once they have browned — this is a diagnosis about next year.

   Damage from moving air rather than from cold alone: a houseplant beside a door, an opening window or above a radiator loses water faster than it can replace it, and drops leaves or browns at the edges. The tell is that the damage is worse on the side facing the draught.

   Points towards it

   • · nothing happened recently, because the cause was last summer — which is exactly why this candidate is so consistently missed
   • · the whole plant went short of water, so buds drop evenly all over it
   • · a root run that is dry now was probably dry last summer too

   Argues against it

   • · a frost immediately before the buds browned is a simpler and more likely cause — this rules it out entirely.

   Check this next

   Ask about last July and August rather than about this spring, and check whether the drop is even. Drought-set bud drop is uniform over the whole plant and happens in mild weather; frost damage is one-sided and follows a cold night.

   What to do now

   Water it properly through July and August this year — that is when the buds for next spring are made — and mulch the root run. A camellia in a pot or against a wall needs watering in summer long after everything around it has stopped needing it.

Narrow it down

This page lists everything at once, which is the right shape for reading and the wrong shape for deciding. The interactive tool asks one question at a time, starting with whichever would separate these causes fastest, and stops as soon as further answers would not help.

Opens with the plant and the symptom already set. Nothing you answer is stored or sent anywhere — the answers live in the address bar and nowhere else.

What this does not cover

These are the causes GrowingHQ holds rules for on camellia — not every cause there is. Where several problems look alike, the honest answer is often that they cannot be told apart by eye, and a page that named one would be guessing. If none of the above fits, the general flowers dropping without setting fruit page lists causes across all plants, and the Camellia profile lists the problems it is prone to.
