Confession: I moved 30 houseplants to the balcony for summer and now I fear the return trip

They're THRIVING out there. The monstera put out three leaves in a month, the hoyas are blooming, everyone's living their best life. But September me has to bring all of this back inside, and I know from bitter experience that outdoor summer = hitchhikers. Last year I imported a thriving colony of spider mites that took until February to fully evict. What's everyone's re-entry protocol?

Hose them down thoroughly a few days before the move (undersides of leaves especially), then quarantine the returnees in one room for two or three weeks before they rejoin the collection. Annoying, works.

Also acclimate the light change in both directions — same as you (hopefully) hardened them off going out, ease them back in. Straight from balcony sun to a dim living room and they'll sulk and drop leaves, and a sulking plant is a buffet for whatever pests made the trip.

Check the drainage holes. That's where the ant colonies and earwigs ride in. I lift every pot and look underneath before anything crosses the threshold. Learned this the way everyone learns it.

the drainage holes. of course. last year's mystery earwigs suddenly make so much sense. thank you and also I'm itchy now

my re-entry protocol is one room, three weeks, and a level of leaf-underside inspection that borders on the forensic. one spider mite outbreak radicalizes you permanently
