What does it mean when my house plant's leaves are yellowing?

Question

The tips of the leaves are slightly brown and dry too...

Too much or too little water? Too much or too little sun?

Answer 1

Depends on the type of plant, really. Anybody who's answer here does not address that doesn't know too much about plants.
You are doing something wrong, but the list can get long as to what. Too much or too little sun, or water, or dirt, or it could be too cold where you have it, or it could need more phosphates in the soil, or iron in the soil.
Do you know what type of plant it is?
Just let me know, and I bet we can come up with a plan to fix it.

Answer 2

Apparently there are many reasons a plant may yellow - I have over-watered as well and have had issues with leaves turning sickly yellow. There are in fact other reasons the leaves may be yellow, including disease and nutrient deficiencies. You may want to read the article below while looking at the leaves to see if maybe they are just the old leaves, or if there is another problem going on.

Answer 3

If you have had this plant in the hot sun for a period of time without enough water it could be leaf burn on the stressed plant, if so keep it from direct sunlight and keep the soil moist. The leaves may drop- but it should recover. If the soil has been overly moist I would suggest repotting with a good potting soil.

Answer 4

you are using tap water and the chlorine is turning the leaves yellow. If you have to use tap water put it in a bowl for 24 hours before using it so the Chlorine will evaporate. You may also be giving the plant to much Sun light.

Answer 5

yellowing leaves usually means too much water.
Put your finger into the dirt, if it is moist near the top do not water.
Did you have these outside during the summer? If so they go
through a shock to their system when they are brought indoors.
They may loose some leaves during their adjustment.
(thereby the brown and dry tops)
