When to plant tulip bulbs in zones 8 to 10
Quick answer
In zones 8 to 10, tulips go in late, and only after their time in the fridge. UC Master Gardeners in south Placer County, California, plant between Halloween and Thanksgiving. Texas Extension in San Antonio plants anytime in December after 60 or more days of chilling. LSU AgCenter plants in late December or early January, because warm soil can undo the chilling. NC Extension in Goldsboro, zone 8a, plants in November once the soil is below 60°F. Two of these windows open after the area's typical first frost and two open before it, so the frost date alone doesn't set the week.

The windows
Four warm-zone windows, side by side
Farther north, tulips go in by late October. In the warm band the window slides toward winter. The reason is soil temperature: LSU says planting chilled bulbs into soil that is still too warm can cancel the chilling and lead to poor blooms. NC Extension waits for the soil to drop below 60°F.

| Extension source | Wording | Nearby station (zone) | 1 in 10 first frost | Typical first frost |
|---|---|---|---|---|
| UC Master Gardeners, Placer County | between Halloween and Thanksgiving | Auburn, for Roseville (9b) | November 15 | December 5 |
| NC Extension, Wayne County | November, soil below 60°F | Goldsboro (8a) | November 1 | November 12 |
| Texas Extension, Bexar County | anytime in December, after 60+ days chilling | San Antonio (9a) | November 7 | November 28 |
| LSU AgCenter | late December or early January | LSU Ben-Hur Farm, for Baton Rouge (9a) | November 6 | November 26 |
Frost dates are NOAA 1991 to 2020 normals for the station nearest each zip code. The 1 in 10 date is the early edge: about 1 fall in 10 freezes before it.

Your yard
Pick your planting week
The frost date alone doesn't set the week. Roseville's typical first frost is December 5, the latest in the table, yet Placer County starts planting at Halloween. Baton Rouge's is November 26, and LSU waits about a month past it. Use the frost date as a check, then follow the source nearest you.

Look up your first fall frost
Type your zip code into the frost date lookup and note the typical first fall frost. On the frost-free coast the lookup may show no date at all.

Check the fridge count
Make sure the bulbs have had their weeks. Texas Extension asks for 60 or more days before December planting, and LSU at least 6 to 8 weeks.

Plant on a cool day
LSU plants about 5 inches deep and 3 to 4 inches apart in Louisiana. Placer County goes 6 inches deep, in full sun at bloom time.

Write the date down
Put the planting date and the fridge-in date on the bulb map. The bloom date next spring tells you if the timing worked.
Edges of the band
Zone 10 and the frost-free coast
UF/IFAS gives Florida no calendar date, only that pre-chilled bulbs go into the yard in the winter. None of the pages we found gives a week for zone 10. There the nearest guide is Louisiana's late December to early January, with the same rule about cool soil.

Tips and tricks
- Plant in a cool spell. Pick a stretch of cool days inside your window. Warm soil right after planting is what LSU warns about. (LSU AgCenter, It's time to plant tulips, hyacinths (2016))
- Plant in groups of one color. LSU says tulips look better in masses than in single rows, with each color in its own group. (LSU AgCenter, It's time to plant tulips, hyacinths (2016))
- Pots work too. LSU grows chilled tulips in pots outside in a cool, shady spot, then moves them into the sun once the shoots are about an inch tall. (LSU AgCenter, It's time to plant tulips, hyacinths (2016))
- Mark the spot. Put a stake at each group, so nobody digs there before the shoots show.
Common questions
Questions
When should I plant tulip bulbs in zone 9?
It depends on where in zone 9. UC Master Gardeners in south Placer County say between Halloween and Thanksgiving, Texas Extension in San Antonio says anytime in December, and LSU AgCenter says late December or early January. All three chill the bulbs first.

Can I plant tulips in December or January?
In the warm band, yes, if they have been chilled. Texas Extension plants in December after 60 or more days, and LSU plants in late December or early January.

Why not plant tulips in October in the South?
LSU says the soil may stay warm until late December, and planting chilled bulbs into warm soil can cancel the chilling.

How deep do tulips go in warm zones?
LSU plants about 5 inches deep, 3 to 4 inches apart, and says Louisiana plants bulbs less deep than farther north. Placer County goes 6 inches deep.
