This morning I harvested what I could (ripe or otherwise) from the plants in my EBs and then pulled them out. The tomatoes and peppers were easy, the beans I just detached the trellis netting from the wall and folded the whole thing up like a leafy blanket. The squash was a chore.
In the process I discovered a vine borer had found my yellow squash. I also think I might have inhaled at least a dozen whiteflies.

But the boxes are stripped of fertilizer and roots. I flooded two of them because ants had set up shop. After they mostly drained, I slapped a mulch cover on them, drained the reservoirs, and rolled them back into place to be used this fall. I hope that's adequate prep for a period of dormancy.
I still have a Mr. Stripey and a jalapeno in non-EB pots that look healthy. I'll let them hang around a while.
I was so sad at the thought of tearing out my plants...but it was actually kind of cathartic. And now I'm excited to be planning for fall!
