What it is likely to be on chives

   • Royal Horticultural Society: Chives — growing

   Checked 2026-08-13

   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

   • · an outdoor clump dies back completely each autumn and returns in spring
   • · the whole clump yellows evenly together
   • · the season has turned and nothing has been done to the plant

   Argues against it

   • · part of a clump going down while the rest stands is not the season — this rules it out entirely.

   Look at whether the clump is going down evenly or in a patch. The whole clump yellowing together from late summer is the normal end of the chive year, and the base of each plant stays firm and clean when you pull one up.

   What to do now

   Cut the dead leaves off at ground level and leave it. The clump returns in early spring, and this is the moment to lift and divide an old congested one — chives are among the few herbs that genuinely improve from being split every few years.

   Checked 2026-08-13

   A soil-borne fungus that rots the base of onions, garlic and leeks, leaving white fluffy growth studded with small black resting bodies. Those resting bodies survive in soil for fifteen years or more, so a plot that gets it stops being a plot for alliums.

   Points towards it

   • · it spreads outward through the soil, so part of a clump collapses before the rest
   • · the fungus lives in the soil and persists there for many years

   Argues against it

   • · fresh compost in a pot indoors is not infested ground — this rules it out entirely.

   Check this next

   Lift one of the yellowing plants and look at the base of the bulb. White rot grows a dense white fluff there, later studded with black specks the size of a pinhead — a healthy dying-back chive has clean firm roots and nothing on them.

   What to do now

   Lift and dispose of affected plants with as much surrounding soil as you can, and do not compost them. There is no home treatment and the fungus survives in the ground for many years, so the practical response is to grow alliums somewhere else and never move soil or tools between the two areas.

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 chives — 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 Chives profile lists the problems it is prone to.
