Snake plant: falling over
Snake plant leaves fall outward when the base has softened from too much water, or when the plant has stretched toward a distant light source.
Working through the causes
Start with the first one — on snake plant specifically, that's the most likely explanation. Each entry below names the observable that separates it from the others.
Root rot at the base most common
How to tell: Leaves are soft and yellowing at the soil line and pull away easily. The base is mushy.
What to do: Unpot, cut away all rotted tissue, repot the firm remainder into dry gritty mix, and water much less.
Reaching for light common
How to tell: Leaves lean consistently toward the window, stems are stretched and pale, but everything is firm and healthy.
What to do: Move it to brighter light and rotate it a quarter turn weekly.
Top-heavy or pot-bound common in tall plants
How to tell: Roots circling the bottom or emerging from the drainage holes, and the pot tips easily.
What to do: Repot one size up into a heavier pot, or stake it.
Plantroster keeps every photo and every diagnosis for a plant, so "sun-scorched" becoming "sun-scorched and mite-infested" three days later is visible instead of lost.

Should I cut off the affected leaves?
Damaged tissue never turns green again, so removing it is cosmetic — do it if it bothers you, using clean scissors. What matters is whether NEW growth comes in clean. That's your read on whether the fix worked, not the old leaves.
How long until I know it's working?
Give it two to three weeks. Existing damage won't reverse, so you're watching the newest leaves. If those still come in affected after three weeks, the cause you treated wasn't the cause.
