My split leaf philodendron leaves are turning yellow. I have fed them but still happens. What can I do
Split leaf philodendron can be fed a diluted houseplant fertilizer once a month.
Avoid over fertilizing.
This plant needs regular watering. As the soil just begins to dry, water throughly. Distilled water is best as conditioned water may also cause leafs to brown.
A new leaf unfurled and it is pale yellow instead of healthy green. All the other Phil's are fine. It looks as if it's been deprived of almost all color but nothing has changed in location for 3 years. I'm including a pic
A new leaf is often lighter in color and this is perfectly normal.

My split leaf philodendron leaves keep yellowing. I have fed them and used insecticide. I don't know what I am doing wrong. Can you please give me some suggestions.
This could be sunscald from too much direct sunlight. Split-leaf philodendrons usually grow up trees in tropical forests and receive shade from their host tree or their grown as tropical houseplants out of direct sunlight. The light level in the picture seems pretty intense. This article may help:

I have a split leaf philodendron in a pot outside under my patio. The leaves seem droopy. Am I over watering it or is it getting too much sun? It gets the morning sun. I live in North West Florida
Soil should be moist but never soggy.
Potted plants outdoors will need to be watered daily and even twice a day in warm temps.
I would try for dappled sunlight, especially if the plant was recently moved outdoors.

Took "Phil" outside last summer. Roots are 40 yrs old and never failed. Last summer I had vines 9 feet long, but I may have waited too long to bring him in. This winter, I had only 1vine with 1 leaf. Now, that seems to have died. Any rescue?????
I don't think your plant will come back if all green stems and leaves have died.
Treat yourself to a new plant.

I have a very large philodendron selloum that broke off at soil level during a big storm. I would like to reroot it. My thought had been to remove all the air roots in the soil, score the main stalk, apply root tone and replant. Is there a more appropriate way to do this?
Fill a 2-inch pot with 1 part peat moss and 1 part sand uniformly blended.
Select a philodendron stem with at least two nodes and cut it off the plant.
Plant the cutting in the peat-moss blend. Verify that the bottom node is below the surface; roots will sprout from it.
Water the cutting at planting. Keep the soil consistently moist to encourage root development.
Cover the stem with a clear plastic bag to create a warm and moist environment. Set the pot in indirect sunlight.
Dig gently around the stem's base to check for roots once a week. Transplant a newly rooted Philodendron selloum to a 3-inch pot filled with potting mix. Upgrade to a 5-inch container when the roots outgrow the current planter.

The few leaves on my Green Congo Phildendron are spotted. Months ago I made the mistake of spraying it daily along with my Bismarck Palm. How do I bring it back to health?
I would avoid getting water on the leaves when watering.
Make sure the plant soil dries slightly between watering. Make sure the plant has good air flow around it to help avoid fungal diseases.
