Leaves yellowing and flopping after flowering
The foliage of a plant that has recently flowered turning yellow, softening and collapsing, usually looking thoroughly untidy. On spring bulbs this is the normal end of the growing season and the single worst thing to tidy away; the observation that matters is what the plant is and when it flowered.
What causes it, and how to tell them apart
Work down the list making the observation under each heading. GrowingHQ will not guess which one you have — the observation is the answer.

How to tell
The plant is a spring bulb, it flowered within the last month or two, and the yellowing is progressing evenly from the leaf tips down. Nothing is spotted, and nothing smells.

If it is this, do first
Leave it entirely alone for about six weeks after flowering. The bulb is rebuilding next year's flower out of those leaves.

How to tell
Not a leaf symptom at all: if fruitlets rather than leaves are being shed a few weeks after flowering, the plant is self-thinning and the foliage is incidental.

If it is this, do first
Check whether it is the leaves or the young fruit that are dropping before doing anything.
