Q.Impatiens Yellow leaves
My Impatiens leaves are turning yellow. Am I watering too much or not enough? They are in the shade until about 1 or 2 in the afternoon then direct sunlight until sunset. They are in boxes and pots. Thank you very much for your help.
Generally, yellowing of the leaves is often attributed to too much water, which can also spawn fungal infections. The brown spots can result from water that has splashed on the foliage or fungal black spot. Back off on water and see if it helps at all. If not, the problem is likely due to a fungal infection and the plants will usually not survive. However, impatiens propagate easily so it may be possible to clip a healthy cutting (or two) and root it in case replacement of the plant is necessary.
