What to Plant in March

The winter rains slow down, the air smells fresh, and you’re itching to get into the garden. What can you plant in March, inside or outside, in the San Francisco Bay area?
March is one of the biggest months for planting in the San Francisco Bay area. It’s the time for planting artichokes, hops, rhubarb, grapes and berries, and just about all the cold season crops outside. Indoors, you can start your tomatoes, peppers, eggplants, and any brassicas that you want to plant outside in the months ahead.
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.
