I presume you are referring to Brazilian Pepper, a large nonindigenous invasive bush that, along with Potato Vines, is the target of many eradication efforts. The BP numbers along the west coast have been greatly reduced over the last couple of decades, but they are still common in rural areas, and the bees do like them.
If memory serves, you only have two or three hives, so what will you do with all that honey? I only have one and I’m still eating last fall’s honey.
I never take the whole super, I take out 6 or 8 frames depending on how full the frames are, and if there is a flow on. I look and see how the hive is doing and decide accordingly. There have been times when I close back up and leave empty handed. I also never feed them and they have flourished for years. Mine are feral mutts, and who would feed them in the wild?
I believe local conventional wisdom is to leave a medium super for a healthy hive through winter, but winters can vary greatly. I mostly don’t bother the bees too much, they know what they’re doing.
