Are these greens too close to the building or not? I heard different people say differnt things: some recommend 6 inches clearance between greens and the building; but some said it's ok to leave as it is now. Should I worry about these greens? The concern is that plants will hold the water near the building or attract insects, and thus damage the building in the long run
Another question: should I remove leaves on the ground and below the vines?
If your house had wood siding or other siding that allowed the vines to grow under it, then I would say keep it away. Since you have brick veneer, that will not be an issue, It may attach itself to your brick if it is a climbing vine, that would be the biggest issue other than the vent you have in the picture. The vine can grow into and through the screen mesh of the vent.
No need to remove the leaves unless it gets really deep. and it covers the vines.
