What to Plant in September

Even as fall looms ahead of us, our warm September weather keeps the tomatoes, cucumbers, and gourds growing strong. And while the wild blackberries in full sun may have shriveled up, the ones in shady spots are just now fruiting plump, tasty berries. Here is a list of what you can plant in your Bay Area garden in September.
This list is based on my planting calendar, which is a great reference when you are choosing what to plant and what to prepare for each season. I’ve included sources for each plant and some notes to better help you in planning your garden this year.
