When to plant tulips

Plant tulips in the fall, before the first frost, so they have time to establish roots before producing spring flowers.

The window: Fall, before the first frost. In most of Western Oregon, October and November are ideal, with planting possible as late as mid-December if the soil is still workable. In colder climates such as Central and Eastern Oregon, plant earlier, from late September through October, to allow two to three weeks for root growth before the ground freezes.

Tulips are planted in the fall because they need time to establish roots before producing spring flowers.
Plant before the first frost for an early to late spring or early summer bloom.
In colder climates, allow two to three weeks for root growth before the ground freezes.
Bulbs can be planted until the ground is frozen, or as late as mid-December if the soil is still workable.

The mistake to avoid: In colder climates, don't wait past late September through October, since tulips need two to three weeks for root growth before the ground freezes.
