Hello,

I have some Ivies; mostly clippings from friends that sit on my desk under a
150W incandescent light bulb. I've had them for some time now and they seem
to be thriving well but occasionally a leaf will yellow and I'm wondering if
this is due to over watering or something more sinister like a fungus or
insect.

They are planted is generic potting soil that has a release fertilizer
included. I don't have them on any particular watering schedule and instead
rely on the wilting of the leaves to tell me that it's time that they want a
drink to quench their thirst.

Whenever a leaf turns yellowish I clip it for fear that it's something that
will spread to the rest of the plant.

I know absolutely nothing about caring for them and figure that the strong
will survive. But I'd sure would like to help them live as long as possible
if someone willing with some hints. I have no idea what type of Ivies they
are but I've included pictures of the problem and the plants here if you'd
please take the time to have and look and pass on some advise. I thank you
for reading and your time.
