Latest Planting Times for Spring-Flowering Bulbs
If you missed Southeast Michigan’s early fall planting window, don’t worry, there’s still time to get your spring-flowering bulbs in the ground. Timing is important, but with a little flexibility and attention to soil temperature, you can enjoy a colorful display come April and May.
Ideal Planting Window
In Michigan, the best time to plant spring bulbs like tulips, daffodils, crocuses, and hyacinths is from late September through early November. The goal is to plant before the ground freezes but after soil temperatures drop below 60°F, which helps prevent premature sprouting.
For Southeastern Michigan, that means you can often plant through mid to late November, especially during mild falls.
If you’re running behind, you can plant bulbs right up until the soil freezes solid, which typically happens in late November or early December. If the ground is still workable, it’s not too late.
Planting Depth and Spacing Guide
Proper depth and spacing are key to helping bulbs survive Michigan’s freeze-thaw cycles and bloom reliably in spring. Here’s a quick guide for common bulb types:
Depth is measured from the top of the bulb to the soil surface.
Tips for Late Planting
Check soil temperature: Use a soil thermometer if possible. Bulbs do best when soil temps are around 40–50°F.
Avoid soggy soil: Choose well-drained areas—bulbs rot easily in waterlogged soil.
Mulch for protection: After planting, cover beds with 2–3 inches of mulch (like shredded leaves or straw) to insulate bulbs from extreme cold.
Store if you can’t plant: If the ground is already frozen, store bulbs in a cool, dark, and dry place (like an unheated garage) at 35–45°F, then plant them as soon as the soil softens.
Final Thoughts
In Michigan’s unpredictable fall weather, flexibility is your best tool. As long as the soil isn’t frozen, you can still plant spring bulbs—sometimes even into early December. With proper depth, spacing, and a protective mulch layer, your late-planted bulbs will rest through winter and reward you with blooms as soon as spring arrives.
