Those Crepes look like they been butchered up pretty good every winter. The shape is all F'd up. In ten years I've never had a bad aphid issue on the three Natchez Crepes at my place until the July rain event. My Natchez Crepes went on a growth spurt and the aphids tapped into all the extra nutrients that were flowing to feed the new growth. The aphid population did a China syndrome effect. I wish the lady bugs population was able to react as quickly. Usually on the better Natchez, Muskogee, and other Indian named varieties aphids are not an issue and they never get powdery mildew. They will always have a small aphid population but it never gets to the point where honey dew starts to sprinkle down on everything.
