When to plant tulip bulbs in zones 3 to 5

Minnesota Extension says hardy bulbs need a cold period to break dormancy, and that planting in its fall window helps them grow roots before the ground freezes. Up north, that freeze comes early. So the window opens in September and sits right on top of the first fall frost.

That's the big difference from zones 6 to 7. There, Kentucky's window runs about a month past the typical first frost. In zones 3 to 5, the frost lands inside the window, and the ground follows not long after.

Frost dates are NOAA 1991 to 2020 normals for the station nearest each zip code (56601, 55811, 55108, 68701). The 1 in 10 date is the early edge: about 1 fall in 10 freezes before it.

In the table, the typical first frost falls between September 26 and October 8, inside both windows. Use your own frost date to pick which end you plant in. If your frost comes in late September, plant the daffodils and small bulbs in the second half of September and keep the tulips for later.

1. 1

   Look up your first fall frost

   Type your zip code into the frost date lookup. Write down the typical first fall frost and the 1 in 10 earlier date.

2. 2

   Plant the daffodils and small bulbs first

   Get them in during Minnesota's window, mid-September to mid-October. Our rule of thumb: start near the early end if your typical frost is in September.

3. 3

   Leave the tulips for last

   Minnesota says tulips can go in as late as you can get them into the soil. Use them for the cold, late days.

4. 4

   Dig to the right depth

   Plant 2 to 3 times as deep as the bulb is wide. Go 1 or 2 inches deeper in sandy soil and an inch or two shallower in clay.

5. 5

   Water, then mulch

   Soak the bed. Minnesota mulches 2 to 3 inches right away. Nebraska waits until the ground freezes, then adds 2 to 3 inches.

Up north, bulbs get plenty of cold. UVM Extension says daffodils need 12 to 16 weeks of chilling and small bulbs 10 to 12. Counted from November 15, 16 weeks ends March 7, and a zone 3 to 5 winter is still going then. A late planting loses root time instead: Minnesota lists planting too late in the season as one reason bulbs flower poorly the first year.

So put the late slots to the bulb Minnesota names as the exception, tulips, and get everything else in earlier. Our guide to planting before the ground freezes covers the last-minute version step by step.
