Easy Plant bulbs

Why these dates

Like garlic, shallots size up best after a winter in the ground, so in most of the Northwest they go in during fall, after the soil cools but before it freezes hard. In Friday Harbor and the San Juans the first fall frost usually comes around November 10.

West-side valleys. The Willamette Valley, Puget Sound and southern Oregon valleys. Long frost-free seasons, but soil stays cold and wet into May, so warm crops wait for warm soil, not just the last frost.
