what does it mean when a plant turns yellow? too much water or too little light?

Answer 1

G'day mate, plants turning yellow could mean not enough nitrogen. Maybe just needs fertiliser.

Answer 2

Either over- or under-watering can cause leaves to yellow. Check the top 6--12 inches of your soil, or at least stick your finger in.

Many annuals will age from the bottom leaves up as winter approaches.

Definitely consider lack of light if instructions indicate that your plant needs 6 hours of light or more daily and you are not providing it. Likewise, look up lighting requirements for house plants if they are leaning toward whatever light is being provided.

Answer 3

clorosis its definately trying to tell you something does it need to be repoted has it been in a pot longer than a year have you read about the plant is it in the wrong exposure of light does it have good drainage or is it the right soil type make your own soil why pay for it dont let the plants sit in water or is it just the end of the season

Answer 4

As a rule of thumb - if the leaves are soft and kind of rubbery - it's too much
water. If the leaves are kind of hard and break real easy - too little light.
Rule of thumb only, but you're the one who knows the amount of water and
the amount of light.

Answer 5

It's hard to say. Maybe too much water or too little water, or it could be suffering from some kind of deficiency. It may be just ending the season. Wished you gave me more info.

Answer 6

Not enough fertilizer.... the plant is starving. Give it a jag of 20-20-20. You do not say indoor or out and that does make a difference but I'll still stand by fertilizer.

Answer 7

could be a magnesium deficiency, try giving it some trace elements. Gardenias often turn yellow due to this problem.

Answer 8

too little water and or not enuff light

Answer 9

there might not be enough nitrogen in the soil, get a soil pH tester, that will tell you what is needed.
