Too much or too little water?

When I get yellow leaves, it's too much water. Someone with more experience will come along to help you.

Terry; You are the best judge whether a condition of yellow leaves is from how you are treating the plant.

Too much...too little water:
Too little fertilizer....or too much:
Cooler than normal nighttime temperatures can bring about yellowing leaves.

Insects can suck juices from plants and the leaves are the first sign.

Too little light bringing about insufficient photosynthesis.
Damaged roots -- not giving sufficient sustenance to the plant will bring about yellow leaves.

If you have a plant that has yellow leaves, then you should decide which of the above or a combo of them could be the reason and change the way cared for.

I'd say to just keep it simple... cut back on the water and see if your plant doesn't improve.

Thanks for the info.I was referring to a double impatiens plant. I wait until it wilts a bit before watering, it gets mostly shade, but has a lot of yellow leaves. I will fertilize it today and see if it improves.

wilting is a signal that the plant is stressed... using that as an indicator that it's time to water isn't a good thing.... it would be better for the plant if you don't do that.... is it dropping flowers, too?... fertilizer will keep it in better shape to bloom more.... try a liquid fert at one quarter strength every time you water.... is it potted or in the garden?....

Terry, just make sure the soil drains well and increase or decrease the watering as you feel the plant needs it.
A fertilizer with a 2/1/1 ratio should be used for your annuals. Something like 10/5/5 is one recommended.

Depending on how the leaves yellow is one means of determining which of several soil nutrients are in low supply, but that can also be caused by improper watering. Most all plants need an evenly moist soil to be able to uptake soil nutrients and to move those and other nutrients around the plants vascular system, the absence of sufficient moisture prevents that movement. But too much water can cause the same problem. Which is why mulches, and adeqaute levles of organic matter in your soil are very important.
