   Easier to correct than overwatering and easily confused with it, because a plant short of water and a plant drowning both wilt. The distinguishing observation is not the plant at all — it is the compost, and it takes two seconds to check.

   Points towards it

   • · this plant runs out of water faster than any other monstera, and dry compost under a yellowing vine is the likeliest reading rather than an incidental one
   • · a droughted vine sacrifices its oldest leaves first and keeps the growing tip, so the yellowing runs from the base of the stem outward
   • · this is an indoor container diagnosis

   Argues against it

   • · compost that is wet points at the opposite fault, and on an aroid in a chunky mix that is a root problem rather than a thirst one — this rules it out entirely.

   Lift the pot rather than looking at the leaf. This plant is light for its size when it needs water and noticeably heavier for a day or two afterwards, and the difference is large enough to feel because the pot is small relative to the foliage. Then look at where the yellow leaves are: drought takes the oldest leaves at the base of a trailing stem and leaves the tip growing, which is not the pattern a root problem makes.

   What to do now

   Water it thoroughly until water runs from the base, let it drain, and then water again when the top two to three centimetres are dry rather than on a fixed day of the week — this plant needs it more often than its larger relative and the interval changes with the season. The yellow leaves will not turn green again and can be removed at the stem; judge the recovery on whether the growing tip keeps producing.

   The consequence of prolonged waterlogging rather than an independent event: water moulds that are present in most soil and compost become active when roots are deprived of air, and colonise tissue that is already dying. The treatment is therefore the watering, not the fungus.

   Points towards it

   • · an aroid whose chunky mix has been kept saturated has lost the air the roots need, and rot follows quickly in a small pot
   • · a failing root system yellows leaves along the whole vine at once rather than working up from the base, because every leaf is short of the same supply
   • · a move into a much larger pot leaves wet compost that the roots cannot occupy, which is where rot starts on a small-rooted vine

   Argues against it

   • · compost that dries between waterings is not the setting a root rot develops in, and points at simple thirst instead — this rules it out entirely.

   Check this next

   Slide the plant out of the pot and look at the roots, which is quick on a plant this size and settles it in one look. Healthy adansonii roots are firm and pale; rotting ones are brown, soft and slide out of their skin when pulled, and the compost smells sour. Check the stem at the compost line too — a soft, darkened section there means the rot has reached the vine and the plant is saved as a cutting rather than as a plant.

   What to do now

   Take it out of the wet compost, cut away every soft brown root and any soft section of stem back into firm white tissue, and repot into fresh free-draining bark-and-perlite mix in a pot barely larger than what is left of the root ball. Where the base has gone, cut a healthy length of vine with two or three nodes and root that instead — this plant roots readily at the nodes and a cutting is a reliable rescue rather than a last resort. Do not feed until new growth appears.

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 swiss cheese vine — 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 lower leaves turning yellow page lists causes across all plants, and the Swiss cheese vine profile lists the problems it is prone to.
