I have a vine that I planted in the front yard under the eave. It gets no sun, always in the shade. Its base is a nice bunch of green leaves, but the vines that grow out long, their leaves start growing a lighter shade of green, almost yellow. Our soil is great where we live. And I have no idea what kind of vine I have. Can I have some help here please, as I don't know what to do?
Why Are the Leaves Turning Yellow?
The first thing to do is to find what kind of plant you have. You can send us a picture.

There seems a good chance that your plant needs more light than it's getting. If it's planted close to the house, sometimes there is a nutrient imbalance close to the foundations that can affect some types of plant.
Yellow leaves can be a symptom of various causes or as simple as something being even just a bit out of balance. Another good read is "Why are my leaves turning yellow?" by Harley Smith in Maximum Yield USA, March 2014. Can be viewed online. Great source of gardening info
