   A deciduous tree, shrub or cane turning yellow through autumn before dropping its leaves. The plant is withdrawing nitrogen and magnesium out of the foliage and storing them in wood for next spring, which is precisely why the leaves go yellow — the green is being taken back. Diagnosing it as a deficiency inverts what is happening, and the feed that follows arrives at the one time of year the plant has no use for it.

   Points towards it

   • · senescence runs through the entire canopy at once, because it is triggered by day length rather than by anything local to a branch
   • · nothing was done to the tree, and it grew normally all season — which is evidence FOR a seasonal process rather than against it
   • · it is driven by shortening days and cold nights outdoors
   • · old and new wood colour together rather than one ahead of the other

   Argues against it

   • · one branch or one side yellowing while the rest of the tree stays green is not seasonal — nothing about autumn reaches half a tree — this rules it out entirely.
   • · autumn colour takes the veins with the rest of the leaf, so a green vein network held against yellow tissue means something else is going on underneath it
   • · a tree that was recently moved or planted has a much better explanation available for a general yellowing

   Check the date and then check the hedgerow. A fruit tree colouring evenly from September onwards, at the same time as everything else deciduous around it, is doing what it does every year — the yellow is the tree taking its nitrogen and magnesium back out of the leaves and into the wood, which is why a deficiency is the one thing it is NOT evidence for.

   What to do now

   Do nothing, and specifically do not feed — autumn nitrogen on a woody plant pushes soft growth that will be killed by the first hard frost. If the tree carries scab or leaf spot, rake the fallen leaves up and remove them rather than composting them in place, which is a sanitation job rather than a treatment for the colour.

   Yellowing between the veins of the YOUNGEST leaves while the veins stay green. The soil usually contains plenty of iron; what is wrong is that the pH is too high for the plant to take it up. Adding iron to the soil without correcting the pH changes nothing.

   Points towards it

   • · yellow tissue held inside a green vein network is the iron signature
   • · the young leaves at the top of this year's canes go first
   • · it tracks the pH of the soil the row is planted in

   Argues against it

   • · yellowing confined to the oldest leaves cannot be an immobile nutrient, and on raspberries usually means the cane itself is finishing — this rules it out entirely.

   Check this next

   Look at the top third of the NEW canes, which are the ones that will fruit next year. Raspberries are shallow-rooted and dislike lime, and on chalky ground the young leaves at the cane tips go yellow between bright green veins while the leaves lower down stay reasonable — a whole cane yellowing evenly from the bottom is a different problem with a different answer.

   What to do now

   Mulch thickly every spring with composted bark, leafmould or well-rotted manure and water with rainwater where you have it. Raspberries want a slightly acid soil and respond to organic matter far better than to feeding; where the ground is genuinely chalky, growing them in a raised bed of imported topsoil is more durable than treating the symptom each year.

   A herbaceous perennial collapsing to nothing in autumn, or a seasonally dormant houseplant dropping most of its leaves in winter. The plant is intact underground and the top growth is expendable — an alocasia that has shed every leaf but has a firm corm is dormant, not dead, and is most often killed afterwards by being watered as though it were still growing.

   Points towards it

   • · it is last year's canes that die, and they are the woody ones that just carried the fruit
   • · some canes in the row are dying while the new ones beside them are green and growing strongly
   • · nothing was done to the row, and it follows the harvest every year

   Argues against it

   • · every cane in the row going down together, new ones included, is not the biennial cycle and needs a different explanation — this rules it out entirely.
   • · this year's green canes yellowing is the wrong half of the plant for a fruited cane dying back — this rules it out entirely.

   Check this next

   Sort the canes into two piles by hand before diagnosing anything. On a summer-fruiting raspberry the canes that carried this year's fruit die after picking — they are browner, woodier and still holding the old fruit stalks — while this year's green canes stand beside them for next season. Half a row yellow and half green in August is the cycle working, not a disease moving along it.

   What to do now

   Cut the fruited canes right down to ground level as soon as picking finishes and tie in the new green ones to take their place. Thin those to the strongest six or eight per metre; leaving all of them is the commonest reason a raspberry row becomes a thicket that fruits poorly and holds disease.

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 raspberry — 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 Raspberry profile lists the problems it is prone to.
