yellowing split-leaf Philodendron
I have a split-leaf philodendron, which is at least 30 years old. It thrives on my sun porch in the summer and manages to survive in the winter (I'm in Massachusetts). It has developed blonde spots on a few leaves, and the leaf tissue appears to be dying. What should I do?

Yellowing leaves on philodendrons could be attributed to chlorosis, which is caused by a lack of magnesium in the soil. In this case, you would want to apply a balanced liquid foliage houseplant fertilizer that contains macro-nutrients. Yellowing in leaves can also indicate overwatering or too much direct sunlight.
