Expert Note

In October, keep soil evenly moist but avoid waterlogging. Harvest frequently to prevent overripe fruit, and watch for late-season pests like aphids and stink bugs; remove damaged fruit and use row cover if nights turn cold.

Seed & Soil

In Zone 2a, use October for finishing warm-season peppers and tomatoes only if you can protect them from cold nights. If you have space, start or transplant hardy greens and quick crops under cover; otherwise, focus on cleanup and preparing beds for next season.

The Harvest

Harvest peppers and tomatoes now while they still ripen well in cool fall weather. Pick Amish Paste, San Marzano, and Celebrity as they color up, and keep harvesting Anaheim and Poblano regularly to reduce plant stress and prevent losses to cold snaps.
