No — November is not too late to plant tulip bulbs in California. In fact, it is prime time. The UC Master Gardeners of Sacramento County planting schedule lists November through December as the window for tulips, and the UC Master Gardeners of Placer County put the best time to plant between Halloween and Thanksgiving. There is one condition, and it is the whole story: the bulbs must have spent 6 to 10 weeks in a refrigerator first. In most of California, winters are too mild to give tulips the cold they need, so your crisper drawer stands in for winter. Daffodils skip that step entirely — they go straight into the ground in November and December with no chilling at all.
Sophie: These tulip bulbs have been sitting in my fridge for two months. Is that a mistake, or is that the plan?
Sprouty: That is the plan. In California, the fridge is the winter your tulips never got. Plant them now, and they will think they survived a proper cold season.
Why tulips need a fridge in California
Tulips (Tulipa spp., family Liliaceae) evolved where winters are long and cold, and the bulb needs a sustained cold period before it will form a proper flower bud. In much of California that cold simply never arrives. As the UC Master Gardeners of Placer County explain, tulips here "require help in setting flower buds because we cannot count on 6–10 weeks of consecutive winter temperatures of 40°F or below." The fix is to manufacture that winter: "pre-chill the bulbs for 6–10 weeks in a refrigerator crisper just before you plant."
The UC Sacramento bulb schedule gives the same instruction in shorter form: chill tulips (and hyacinths and crocus) in a paper bag in the refrigerator crisper for at least 6 weeks before planting, "to insure strong stems and blooms." The University of California Cooperative Extension's bulb guide (Planning and Planting a Bulb Garden, GN 168) agrees: "Tulips and hyacinths benefit from 6 weeks in the refrigerator before planting."
One more thing the UC sources are blunt about: in California, treat tulips as a one-season show. The UC Placer fall bulb guide notes that tulips and hyacinths "give a great show the first year, but our climate doesn't provide the winter chilling needed for repeat blooming in subsequent years. If you want to grow them, you will have to treat them as annuals and replant each fall." Budget for fresh bulbs every autumn, and the November ritual becomes the point, not a chore.
How to chill tulip bulbs
If your bulbs are already chilled, skip ahead to planting day. If they are still sitting on a shelf, here is the method, assembled from the UC sources:
- Buy early. The UC Sacramento schedule advises buying tulip bulbs in September or October, so they can be in the fridge a full 6 weeks before the November planting window.
- Bag them in paper, not plastic. Put the bulbs in a labeled brown paper bag. The UC Sacramento schedule specifies a paper bag in the crisper section, and the UC Cooperative Extension bulb guide says not to use plastic bags. Label the bag so you know what is inside and when it went in.
- Use the crisper drawer. Set the bag in the refrigerator crisper for at least 6 weeks — 6 to 10 weeks per UC Placer. Never put bulbs in the freezer; the UC Extension guide is explicit that the freezer is off limits.
- Keep fruit away. Do not store bulbs near apples or other ripening fruit. The UC Sacramento schedule warns that fruit gives off ethylene gas "which can destroy flowers inside the bulbs."
- Go straight from fridge to ground. The UC Placer tulip guide instructs: "Go directly from refrigerator to pre-dug holes on planting day." Dig the holes first, then fetch the bulbs — do not let chilled bulbs warm up on the counter.
Planting day: the steps
Once the bulbs are chilled, planting takes an afternoon. Follow the UC numbers:
- Plant between Halloween and Thanksgiving. That is the UC Placer window; the UC Sacramento schedule runs tulips November through December. The UC Placer fall bulb guide calls October and November the optimum planting time in the foothills. The UC Mariposa County November checklist puts it simply: "Plant the bulbs you have chilling in the refrigerator: tulips, narcissus, daffodil, and hyacinths."
- Pick a sunny, well-drained spot. The UC Placer fall bulb guide says to plant bulbs where they will receive at least six hours of sun a day. The UC Cooperative Extension bulb guide calls well-draining soil, rich in organic matter, ideal for most species, and suggests raised beds and containers as alternatives where soil drains poorly.
- Plant 6 to 8 inches deep, 4 to 8 inches apart. Those are the UC Sacramento schedule figures for tulips; UC Placer likewise says to plant 6 inches deep. Set each bulb with the pointed end up and the flat basal plate down — the UC Extension bulb guide's rule is "plant bulbs with the pointed end up and root scars down."
- Water them in. The UC Extension bulb guide's instruction is to "water thoroughly after planting." Rain usually takes over from there in a California winter.
A note on depth, because this site has argued the other side: our own shallow-planting guide makes the case for planting tulips just 3 inches deep for stronger stems. The UC Sacramento schedule lists 6 to 8 inches. This article follows the UC schedule — the depth UC Master Gardeners publish for California conditions — and links the shallow argument below so you can judge the debate yourself.
Pots work too — with one condition. The UC Sacramento schedule notes that in pots, tulip bulbs are planted with the top of the bulb just above the soil surface (daffodils go in with the tip just below it). But a pot does not supply the cold: the UC Extension bulb guide warns that containers and raised beds are not effective for bulbs that need winter chill — so pre-chill tulip bulbs in the refrigerator first, then pot them.
Daffodils: the no-chill alternative
If the fridge routine sounds like too much fuss, plant daffodils (Narcissus spp., family Amaryllidaceae) instead. They are the easy half of this story. The UC Sacramento schedule lists daffodils and narcissus for September through December with no pre-chilling at all, and the UC Placer fall bulb guide says daffodils "return year after year," while tulips need replanting each fall. Plant daffodils 3 to 6 inches deep depending on bulb size, spaced 2 to 8 inches apart, per the Sacramento schedule.
Daffodils carry two more advantages the UC sources flag. First, they naturalize: a planting you make this November can return year after year. Second, rodents leave them alone — the UC Sacramento schedule notes that pocket gophers, chipmunks, ground squirrels and mice avoid daffodils and other narcissus "because of their bitter taste." Snails are the exception: the UC Extension bulb guide notes snails may nibble foliage and blossoms. And if you want blooms indoors for the holidays rather than in the garden, paperwhite narcissus needs no chilling whatsoever, as our guide to planting paperwhites for Christmas blooms explains.
What if you never chilled your tulips?
There are two honest options, and "plant them anyway and hope" is not one of them — unchilled tulips in a mild-winter garden will not get the cold period the UC sources say is required for strong stems and blooms.
Option one: chill now, plant in December. The arithmetic works. Put the bulbs in a labeled paper bag in the crisper today, and six weeks later — around December 19, in the third week of the month — they meet the Sacramento schedule's minimum chill, inside its November-through-December planting window. Six weeks is the minimum, so there is no slack in that plan. Go straight from the fridge to pre-dug holes, as UC Placer instructs.
Option two: buy pre-chilled bulbs and plant them now. Look for bulbs labeled pre-chilled, and plant them the same week. The UC Fresno gardening calendar notes that "tulip and hyacinth bulbs that have been chilled for six weeks may be planted now" in late October into November. If you buy pre-chilled, skip the fridge and plant the same week.
Either way, the deadline that matters is the back end of the window: the UC sources run tulip planting through December and stop there — none of them offers a January planting window.
When will they bloom?
Spring for tulips — and winter into spring for daffodils. The UC Sacramento schedule lists spring as the bloom season for tulips planted now, and winter into spring for daffodils. What you plant in November spends winter quietly building roots, then flowers as the soil warms. The UC Marin Master Gardeners November checklist frames the whole month this way: "Fall is for planting! Winter rains will help develop a strong root system" — and its November list includes "plant spring blooming bulbs" and "plant bulbs for spring color, including daffodils, crocus, freesia and hyacinths."
Enjoy the tulips while they last, then let them go: they are a one-season show in California, and next fall you buy fresh bulbs, chill them for six weeks, and plant between Halloween and Thanksgiving all over again. The daffodils, meanwhile, will come back on their own — the reliable half of the bed, returning year after year.
Quick answers
Is November too late to plant tulip bulbs?
No. November through December is the UC Sacramento planting window for tulips, and UC Placer calls Halloween to Thanksgiving the best time to plant. November is prime time — provided the bulbs were pre-chilled.
Do tulip bulbs need chilling in California?
Yes. California winters do not reliably deliver 6 to 10 weeks of temperatures at or below 40°F, so UC Master Gardeners advise pre-chilling tulip bulbs in a refrigerator crisper for 6 to 10 weeks before planting.
Do daffodils need chilling?
No. Daffodils and narcissus flower well in California without pre-chilling and can go into the ground any time from September through December, per the UC Sacramento schedule.
How deep do I plant tulip bulbs?
6 to 8 inches deep and 4 to 8 inches apart, pointed end up, per the UC Sacramento schedule. Plant in a sunny spot with good drainage and water them in at planting time.
What happens if I plant tulips without chilling them?
They miss the cold period UC sources say is needed for strong stems and blooms. Chill them now for six weeks and plant in December, buy pre-chilled bulbs and plant this week, or plant daffodils instead — they need no chilling at all.
When should I plant spring bulbs in California?
October and November is the optimum window in the foothills per UC Placer, with tulips and daffodils running November through December per the UC Sacramento schedule. Tulips and daffodils go in the ground in fall.
