   A plant switching from leaf or root production to flowering and seed. It is the plant doing exactly what it evolved to do under stress, and it cannot be reversed — which makes bolting a problem of timing and cultivar choice rather than of treatment.

   Points towards it

   • · nothing was done to it — dill is short-lived by nature and flowers on day length rather than on any fault in the growing
   • · a sowing runs up as a block within a week or two of itself, because every plant in it is on the same clock
   • · heat brings it forward sharply, though it does not cause it
   • · it follows natural day length outdoors

   Argues against it

   • · a few plants bolting while their neighbours stand is a local check rather than the seasonal signal the whole row received

   Check this next

   Work out how old the sowing is rather than looking for a fault. Dill sown in May is flowering by July whatever it is given: eight to ten weeks from sowing to flower stem is normal for the plant, and the whole row goes together. If one part of a row has bolted and the rest has not, something local checked those plants instead — and that one is worth fixing.

   What to do now

   Sow a short row every three weeks from April to July and treat each as a six-week crop rather than a plant to keep. That is the entire answer for dill leaf: no cultivar, watering regime or feeding programme keeps a single sowing in leaf for a season. Let the last sowing flower — the umbels are the seed crop and among the best hoverfly plants in a vegetable garden.

   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

   • · dill makes a taproot within weeks and flowers rather than recovers when it is broken, so a moved plant runs up almost at once
   • · a dry root ball at planting turns an ordinary check into a severe one
   • · the plant flowers while still small, so the flower stem is the newest and almost the only growth it has made since the move

   Argues against it

   • · a crop sown where it stands and never moved cannot be suffering from a transplanting check — this rules it out entirely.

   Check this next

   Ask whether these plants were moved, and look at how big they are. Dill that was bought as a pot or pricked out flowers at 20–30cm within a fortnight of going in, while a direct-sown row of the same age is knee-high and still in leaf. Lift one and the taproot will be kinked or broken with a tuft of side roots above it — the size at flowering is the tell, not the timing.

   What to do now

   Sow dill direct where it is to grow and thin to about 20cm rather than transplanting, including from bought pots — a supermarket pot of dill is a dozen seedlings that will bolt within weeks of being split and planted. Where module raising is unavoidable, plant out very young with the compost intact and never let the plug dry.

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 dill — 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 plant running up to flower before it is ready to eat page lists causes across all plants, and the Dill profile lists the problems it is prone to.
