I have been pruning and repotting the greenhouse petunias that will be spending the winter in the heated garage. I'm also taking cuttings as I go. I don't know how well either of these methods will work. I already have some small plants that grew from cuttings taken months ago, but my success rate hasn't been close to 100%. At least one pot each of geraniums and petunias will remain in their original containers for overwintering.
I chopped most of the petunia flowers off a couple days ago, in part because I spotted some aphids. It appears that on petunias, they primarily attack the blossoms. The leaves and stems may be too thick and sticky for them. I have kept one petunia pot intact and will prune it last, just before it comes over to the garage. Last year that was around November 16 (same pot). It is the 2025 purple vein hybrid, and I believe there are two plants in the pot.
Last winter, I pruned the petunias a couple times, and even fertilized them once. I don't know if all 11 varieties (nine 2026 Supertunias, the 2025 hybrid, and the "Red Lodge Red Vein" offspring of the hybrid) will make it through, but I'm sure some of them will.
I have two geranium pots and will keep the one that I have had for years. The other is a hanging basket, and I might just depend on the cuttings I have taken already and let the main plant freeze.
And I want to mention the three zinnias that have been growing in a greenhouse pot but have not yet produced flowers. They've got four weeks max before the temperature is turned down, and then... I always talk tough but they probably will end up in the garage at least for a while if they flower or are very close.
