How this shows up on a Asparagus fern
Yellow, limp fronds at the base
The asparagus fern yellows from the base up. Affected fronds bend rather than snap, and the pot is still heavy several days after watering.
Soil described as moist but well-drained or well-drained is a drainage instruction as much as a watering one. Compost that stays saturated suffocates the fine roots that do the drinking.
Telling it apart: The soil, not the leaf. Wet compost under yellowing leaves points one way and dry compost the other, and the leaves alone will not tell you which.

Why: A stem that is soft or dark at the soil line, in wet compost, has usually been invaded by the fungi and bacteria that thrive where roots and stems sit wet.
What to try:
- Look for any firm, healthy stems or tips above the damage; cuttings from those may root even if the base cannot be saved.
- Throw away the affected compost rather than reusing it, and wash the pot before using it again.
What would settle it: Cut a small slice from the affected stem. Discoloured tissue running up inside it is rot; a clean pale centre means the damage is on the surface.
Most likely thirst

Why: Soil that is dry two inches down cannot supply the water that holds a leaf out straight.
What to try:
- Water until it runs from the drainage hole, then let the pot drain.Useful: pot with drainage holes
- If the water runs straight past a shrunken rootball, stand the pot in water for twenty minutes.
What would settle it: Water it thoroughly and look again the same evening. A thirsty plant usually lifts within hours. One that does not has a root problem rather than a water problem.
Most likely it was thirst, and it has already answered

Why: A asparagus fern that stands up again within a day of watering was short of water rather than damaged.
What to try:
- Check the soil with a finger every few days rather than watering on a fixed day.Useful: moisture meter
- If it dries out within three or four days, look for roots coming from the drainage hole and consider a pot one size larger in spring.Useful: pot with drainage holes
What would settle it: How fast the pot dries now. A asparagus fern that is dry again within a few days may have outgrown its pot, which holds too little compost for the roots it has.

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
