   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

   • · a cold draught or a move near a door or single-glazed window is the usual trigger, and the drop follows within days
   • · an indoor winter problem
   • · the side facing the draught loses leaves first

   Argues against it

   • · nothing changed, and this cause requires an exposure that was not there before

   Check this next

   Stand where the plant is and feel for moving air, then check whether the leaves lost are on that side. A rubber plant drops its lower leaves near a cold door within a week, and the leaves that fall are undamaged rather than yellowed — which separates it from watering problems.

   What to do now

   Move it a metre further into the room, away from the door, window or radiator. The leaves already shed do not come back, so judge the move by whether the drop stops rather than by recovery.

   Not a problem, and included as a candidate because it is one of the commonest explanations for a single yellow leaf on an otherwise healthy plant. Every plant sheds its oldest leaves; a differential that cannot return 'nothing is wrong' will always find something to blame.

   Points towards it

   • · only the lowest, oldest leaves are shed and the top of the plant looks well
   • · one or two leaves rather than a general collapse
   • · nothing changed, which is what you would expect of an ordinary process

   Argues against it

   • · a cold draught or a move is a specific trigger, and a plant that dropped leaves within days of one is not simply ageing — this rules it out entirely.

   Check this next

   Look at which leaves went and what the rest of the plant is doing. A rubber plant sheds its lowest leaf every few months as it grows taller, and the leaf that falls is whole and green-to-yellow rather than marked — a plant dropping leaves from the middle or the top, or dropping several at once, has something wrong with it.

   What to do now

   Remove the fallen leaf and change nothing. This is the diagnosis most worth getting right on a houseplant, because the usual response — watering much less on suspicion of root rot — damages a plant that was perfectly healthy.

   Wilting, leaf drop or a stall in growth in the days after repotting, planting out or moving. Often not a problem at all but a normal adjustment, and the commonest mistake is to react to it by changing something else — which turns a recoverable check into a real decline.

   Points towards it

   • · the drop follows the move rather than anything about the care, and a plant that has just come home from a shop or across a room has had the largest change in light it will ever get
   • · this is an indoor acclimation
   • · the plant sheds the leaves it built for brighter conditions and keeps its newest growth, so the loss runs from the bottom and the inside outward

   Argues against it

   • · a plant that has stood in the same place undisturbed has nothing to acclimatise to, and its leaf drop needs a different explanation — this rules it out entirely.
   • · a cold snap is a specific injury with its own pattern and a much more likely reading than adjustment
   • · sodden compost gives a root explanation for leaf loss that does not depend on the plant having been moved

   Check this next

   Date it and then watch whether it stops. Acclimation begins within a week or two of the plant arriving or being moved, takes the older and lower leaves rather than the newest, and tails off within about a month — and crucially the growing point stays firm and green throughout, and often pushes a new leaf while the old ones are still falling. Leaf loss that starts out of nowhere on a settled plant, that takes the newest growth, or that keeps going past six weeks is not this. Check the compost as well: acclimation happens at any moisture level, so wet compost points somewhere else.

   What to do now

   Leave it alone, which is the hardest and the correct answer. Put it in the brightest position it can have without direct midday sun, keep the watering steady and slightly on the dry side while it has fewer leaves to supply, and do not repot, feed or move it again during the adjustment — each of those adds a second change to a plant already handling one. Pick the fallen leaves off the compost. Expect it to settle within a month or so and to look thinner than it did in the shop, which is the plant correctly sized for the light it now has rather than a plant in decline.

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 rubber plant — 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 sudden leaf drop page lists causes across all plants, and the Rubber plant profile lists the problems it is prone to.
