Fall is one of the best times to garden in pots in the East Bay. Our mild Mediterranean climate lets you grow leafy greens, kale, root veggies, and herbs in containers from now through spring, and a few cool-season flowers keep pollinators fed along the way. As a San Leandro plant nursery, we see the same thing every year: gardeners pack up their tomato pots in October and miss the best growing window. Here is how to set up your containers, what to plant, and how to keep everything healthy through the rainy season.

If you are planting in the ground instead, start with our guide to starting a fall vegetable garden in the East Bay. This post is for patios, balconies, and front porches.

Why Is Fall a Great Time for Container Gardening?

Cool-season crops grow best when average temperatures sit between 55°F and 75°F, according to the UC Master Gardener Program. That describes most East Bay days from October through March, even with the occasional heat wave or storm.

Pots also give you an advantage once the rain starts. You control the drainage, and you can move containers around. As the winter sun drops lower in the sky, slide your pots to the sunniest spot you have. Most cool-season edibles still want at least six hours of direct sun.

Can You Plant Vegetables in December and January?

You can, but it is not the easy route. Cold weather and short days slow everything down, so new plants take longer to root in and grow. There is also a supply problem. Regional growers time their vegetable and herb seedling production for spring, so starts are scarce at any plant nursery in December and January. Our veggie tables, like those at most garden centers, fill back up in February.

Growing from seed is the only workaround. It needs a spot with strong light and warmth, and you would start six to eight weeks before transplanting. We do not usually recommend it for beginners. Plant this fall, or wait for fresh starts in February.

How Do You Set Up Containers for the Rainy Season?

Match the Pot to the Plant

Lettuce, radishes, and herbs do well in wide, shallow pots and window boxes. Broccoli, cabbage, and kale grow into big plants, so give each one its own deep container. Half wine barrels, large glazed pots, and fabric pots all work well. Terra cotta breathes and dries out faster, which suits rosemary, thyme, and sage heading into a wet winter.

Start With Fresh Potting Mix

Summer crops leave container soil tired and compacted. Replace it, or at least refresh the top third with a quality potting soil such as E.B. Stone’s EarthFirst or Foxfarm Ocean Forest. Never fill a pot with garden soil. It is too dense and will smother roots. Not sure about the difference? Our guide to potting soil vs. garden soil explains it.

Skip the Gravel and Keep Drainage Holes Clear

A layer of gravel at the bottom of a pot does not improve drainage. According to University of Missouri Extension, it works against you, because water “perches” in the soil above the gravel and keeps the root zone wetter. Fill the whole pot with potting mix instead.

Once the rains begin, set planters on pot feet so water can escape, and empty saucers after every storm. Root crops sitting in standing water are a fast track to root rot.

What Are the Best Cool-Season Vegetables for Pots?

The easiest wins are leafy greens, brassicas, root veggies, and a few climbers.

• Leafy greens: Lettuce, arugula, spinach, Swiss chard, and baby bok choy are the simplest fall container crops. Harvest the outer leaves as you go and the plants keep producing for weeks.

• Kale, broccoli, and cabbage: Kale is the MVP of winter containers, since one plant in a large pot can feed a household for months. Broccoli and cabbage also do well when planted from starts, one plant per container.

• Radishes, carrots, and beets: Radishes are the fastest crop you can grow, often ready in about a month, and they are the easiest root crop from seed. Carrots and beets can be sown directly, but germination can be tricky, so many gardeners buy seedlings. Choose short or round varieties and use deeper pots.

• Green onions and peas: Bunching onions grow quickly in narrow pots. Snap peas and snow peas climb happily up a small trellis tucked into a deep container.

Which Herbs Grow Best in Pots This Time of Year?

Cilantro and parsley are at their best in cool weather, since heat pushes them to bolt. Rosemary, thyme, and sage prefer to dry out between waterings, so give them terra cotta and a sunny, sheltered spot.

What Pollinator Plants Can You Grow in Containers in Winter?

Pollinators do not take the winter off in the East Bay. Anna’s hummingbirds stay year-round, and bees forage on warm winter afternoons.

• Sweet alyssum: A honey-scented carpet of tiny flowers that spills over the edge of a pot and draws beneficial insects. UC Master Gardeners in Stanislaus County suggest planting it around the base of citrus trees, which works just as well with potted citrus.

• Calendula: Cheerful orange and yellow blooms with edible petals. UC Master Gardeners of Santa Clara County list it among the flowers that support beneficial insects.

• Rosemary: A kitchen herb that doubles as a winter bloomer bees love.

• Manzanita: Compact native varieties bloom in late winter with small, bell-shaped flowers that hummingbirds and early bees seek out. Choose a large container and a sunny spot. Our California natives section is a good place to start.

Pro tip: Pair a pollinator plant with an edible in the same pot. Tuck sweet alyssum around the edge of a kale container, or plant calendula next to lettuce. You get more flowers, more beneficial insects, and fewer aphids if the weather turns unseasonably warm.

How Do You Care for Containers in Winter?

• Watering: Check soil moisture with your finger before watering. Pots under eaves or on covered patios can stay dry after a storm, while exposed pots may need no extra water for days.

• Feeding: Plants grow slowly as days shorten, so feed lightly. A liquid fish and kelp drench every few weeks gives leafy greens a gentle boost.

• Pest patrol: Wet weather brings out snails and slugs, so check pots at dusk. Watch kale and broccoli for aphids and cabbage loopers during warm spells. The easiest control is a blast from the hose or picking pests off by hand.

Why Shop a Local Plant Nursery for Fall Containers?

A local plant nursery can match the right plant, pot, and potting mix to your space in one trip. At Evergreen Nursery, our staff can help you choose pots, planting mixes, starts, and flowers that fit your patio or balcony.

FAQ

Can I grow vegetables in containers over winter in the East Bay?

Yes. Our mild winters rarely bring hard frost, so leafy greens, kale, root veggies, and cool-season herbs grow in containers from fall through spring.

What size pot do I need for broccoli or kale?

Give each plant its own large container. One 5-gallon nursery pot or similar container per plant works well. Fabric pots are a good option because they are lightweight and easy to move.

Do I need to replace potting soil every season?

Not always. Refresh the top third with fresh potting mix and compost. Fully replace any mix that is compacted or that held a diseased plant.
