Spider plant leaves turning yellow is such an eyesore; find the cause and solve it easily

Spider plants (Chlorophytum comosum) are loved by many artistic young people because they are easy to grow and keep alive. Even though they are tenacious, there are still plenty of problems during cultivation. For example, many people's spider plants develop yellow leaves; a pot that should be lush and green is now half yellow and half green, which is truly an eyesore!
Don't be afraid if your spider plant's leaves turn yellow; its vitality is still very tenacious. Quickly find the cause and treat the root problem, and your spider plant still has a great chance of surviving, so don't give up on it yet! In summary, spider plant leaves turn yellow mainly because one or several of the following factors have gone wrong: water, sunlight, ventilation, fertilizer.
(Case one)
Case one: the tips of the leaves turn yellow or look scorched. This situation may be caused by stuffiness (poor ventilation) + heat (full sun or lack of water). For appearance's sake, the first step is to cut off the yellowed leaf tips. If it is kept indoors, move it outside to let it get ventilation; if it is exposed to full sun, move it to a shaded spot; if the soil is already dry, be sure to increase watering.
(Case two)
Case two: almost the entire leaf turns yellow. This situation may be caused by improper moisture (too much or too little) + sunlight (insufficient) + fertilizer (mainly too much). The first step is also to trim off the entire yellowed leaf. If there has been too much or too frequent watering recently, reduce it accordingly; if it has been kept indoors for a long time, it is best to move it outside to get more sunlight; if there has been frequent fertilizing recently, stop fertilizing and switch to plain water only.
(Case three)
Case three: almost the entire spider plant has turned yellow or wilted. If the situation is already this serious, it is likely caused by long-term neglect of the plant's growing conditions, so it should be a combined cause of the first and second cases above. At this point, you can cut off the whole spider plant at the top and trim away all the diseased leaves.
Then place it in a ventilated, shaded spot for care. After about half a month, you will see new leaves sprouting. At this time, do not expose it to full sun, and do not use any fertilizer; simply water it and keep the soil moist.
