Q.impatients
I have bagged impatients on front porch with minimal sun..at first they were doing great but now they are turning yellow..more at the bottom of the bag..could i be watering them too much? Should i lay them in the sun for awhile to dry out? I felt the bottoms thru a hole and yes it is damp but wouldnt say soaked..i dont see any bugs on them. Thanks for answering my questions

Generally, yellowing of the leaves is often attributed to too much water, which can also spawn fungal infections. 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 them in case replacement of the plant is necessary.
