How to Plant Spring Bulbs in the East Bay (Plus Paperwhites and Amaryllis for Winter Color)

Key Takeaways

• Mid-November is prime bulb planting time in San Leandro and the East Bay, and most spring bulbs can go in the ground through early December.
• This year's outdoor lineup: Narcissus (aka Daffodils), Freesia, Dutch Iris, Crocus, and Tulips.
• Daffodils, Freesia, Dutch Iris, and Crocus need no special treatment in our mild winters. Chilling Tulips in the fridge first is optional, not required.
• Plant Paperwhites indoors now for fragrant blooms around the holidays, and Amaryllis for big, bold color in the new year.
• Good drainage is the golden rule. Bulbs rot in soggy soil, so amend clay with pumice, not sand.
• Most of these bulbs are toxic to dogs and cats, so plant with curious pets in mind.

Bulbs are about as close to a sure thing as gardening gets. Each one arrives pre-packed with the energy it needs to bloom, so your job is mostly to tuck it in pointy end up and let our cool, rainy East Bay winter do the rest.

When to Plant Spring Bulbs in the East Bay

In San Leandro, Oakland, and the surrounding East Bay, spring bulbs go in once nights cool down, usually October through December, according to UC Master Gardeners of Contra Costa County. Mid-November sits right in the sweet spot, though your microclimate matters: a cool hillside garden and a sunny yard in the flats can be a week or two apart.

Our 5 Outdoor Bulbs for Spring Color

Narcissus (aka Daffodils)

The low-maintenance overachiever. Daffodils naturalize easily, coming back and multiplying year after year, and gophers and deer leave them alone. Plant in clusters for the biggest impact.

Freesia

Freesias are native to South Africa, so they feel right at home in our Mediterranean climate, and their fragrance will stop you in your tracks. Plant them in groups near a walkway where you'll catch the scent, or grow them for cut flowers.

Dutch Iris

The elegant blue-purple iris of spring florist bouquets. Dutch Iris love full sun and good drainage. Plant in groups.

Crocus

Low-growing and cheerful, crocus are among the earliest bulbs to bloom. They get enough natural chill outdoors here, so no fridge time needed. Tuck them along borders or in pots where you'll see them up close.

Tulips

The showstoppers. Standard hybrid tulips often behave like annuals in mild-winter areas, so many gardeners plant fresh bulbs each fall. Species tulips are more likely to come back year after year. Gophers and squirrels love tulips, so plan accordingly (see our Pro Tip below).

Should You Chill Your Tulips First?

It's optional. UC Master Gardeners of Contra Costa County suggest about 6 to 8 weeks of chilling for our zone if you go that route. On the other hand, UC Master Gardeners of Napa County report a Northern California trial where pre-chilled tulips bloomed only about two weeks earlier with slightly taller stems.

Our take: chill them if you want a little extra height and polish, or plant this weekend and enjoy the show either way.

Pro Tip: If you do chill tulips, keep them in a ventilated paper bag in the crisper drawer, and never store them next to apples or other ripening fruit. The gas fruit releases can damage the flower inside the bulb. Go straight from the fridge to the planting hole.

How to Plant Bulbs in the Ground

1. Pick a Sunny Spot

Choose a location that gets plenty of sun while the bulbs are growing and blooming.

2. Fix Drainage First

Bulbs rot quickly in soggy soil, and heavy East Bay clay holds water like a sponge. In our experience, compost alone is never enough to fix it. For real drainage, aeration, and soil structure, mix E.B. Stone Volcanic Pumice into the planting area, the same approach we recommend for planting fruit trees. Then blend in E.B. Stone Top Soil Plus, a compost-based amendment with no added fertilizers, for organic matter. Skip sand, which tends to create more problems in clay than it solves. Vermiculite helps too, but it gets pricey for in-ground beds. If your yard still drains poorly, plant in raised beds, mounds, or containers. Not sure how your soil drains? Our El Niño garden prep guide walks you through reading your yard's drainage.

3. Plant at the Right Depth

Set each bulb pointy end up. Contra Costa's UC Master Gardeners recommend planting about three times as deep as the bulb is wide, so a 2-inch tulip or daffodil bulb goes about 6 inches deep, while small bulbs like crocus and freesia sit just a few inches down. When in doubt, check the bulb package.

4. Water, Mulch, and Relax

Water well after planting and add 2 to 3 inches of mulch. Winter rains usually take it from there; water during dry spells so the soil stays lightly moist.

Pro Tip: Gophers and squirrels treat tulip bulbs like a snack bar. Plant them in wire baskets sunk into the ground, in raised beds, or in containers. Or tuck daffodils in alongside, since critters skip them.

How to Plant Bulbs in Pots

No yard? Bulbs are perfect for patios and balconies in Alameda, Hayward, and beyond.

• Choose a deep pot with drainage holes.
• Fill with a quality, well-draining potting mix.
• Crowd bulbs closer together than you would in the ground for a full display.
• Try "bulb lasagna" layering: tulips at the bottom, daffodils or Dutch Iris in the middle, crocus on top for months of staggered color.

Indoor Bulbs to Plant Now

Paperwhites

Paperwhites need no cold period at all. Industry resource Dig.Drop.Done. says they bloom about 5 to 6 weeks after planting, so bulbs started this week should flower right around the holidays. Fill a bowl at least 3 to 4 inches deep most of the way with pebbles, set the bulbs pointy end up, and add water to just below the base of the bulbs. Water touching the bulbs can cause rot. Give them bright, indirect light. Plant a new bowl every 2 to 3 weeks for fragrant blooms well into February.

Pro Tip: Floppy Paperwhites usually mean a too-warm room. Grown at a cool 60 to 65°F, they stay shorter and bloom longer. Keep them away from heaters, since very warm rooms can make the flower buds dry up.

Amaryllis

Big bulb, bigger blooms. Choose a deep pot no more than 2 inches wider than the bulb, and plant it with the top third exposed above the potting mix, as UC Master Gardeners of Santa Clara County recommend. Water sparingly at first, then more generously as the flower stalk grows. Keep it in bright light at normal room temperature. According to Dig.Drop.Done., most Amaryllis bloom 8 to 10 weeks after planting, so a bulb planted now brings bold color to the new year. Bulbs labeled as Christmas Amaryllis are specially prepared to bloom faster, in about 4 to 6 weeks.

Frequently Asked Questions

Is it too late to plant spring bulbs in November?

Not at all. November is ideal in the East Bay, and most bulbs can be planted through early December.

Do I need to dig up my bulbs after they bloom?

No. Let the leaves yellow and die back naturally, since they're recharging the bulb for next year. Daffodils will often return and multiply, while hybrid tulips usually perform best as fresh bulbs each fall.

Are spring bulbs safe for dogs and cats?

Mostly no. The ASPCA warns that tulips, daffodils, and iris can cause vomiting, diarrhea, and drooling, with the highest concentration of toxins in the bulbs, and spring crocus can cause stomach upset. Paperwhites (a type of Narcissus) and Amaryllis are also toxic to pets. Freesia is generally considered pet-friendly. [FLAG FOR EDITING: verify Freesia's listing directly in the ASPCA plant database before publishing.] When in doubt, check the ASPCA plant database.

Do bulbs need fertilizer?

Healthy bulbs already contain the nutrients for this season's bloom. A bulb food or bone meal at planting helps them recharge for next year. Browse our fertilizers and amendments.
