Spring bulbs go into cool autumn ground and show nothing for months, until green tips push through at the end of winter. In Maryland, the planting window falls in fall, and the bulbs you choose decide how many flowers the squirrels and deer leave you.
When to Plant Tulips and Daffodils in Maryland
October is the month to plant tulips and daffodils in Maryland, and the job can also be done in September or November if the soil cooled early or late. A bulb’s year here runs like this.
- In early fall, buy bulbs while garden centers still have a full selection, and keep them somewhere cool and dry until planting day.
- Through the fall, skip the refrigerator. Maryland winters supply enough cold on their own, so tulips and hyacinths go straight into the ground.
- In October, dig the beds and set the bulbs once the soil has cooled. In Baltimore, the first fall frost typically arrives between October 26 and November 5, which tells you the ground is cooling well before the soil freezes.
- After planting, spread a layer of mulch over the bed so the soil stays evenly cool through winter.
- As winter ends, green tips break the surface, and the flowers follow in spring.
Maryland spans hardiness zones 5b to 8a in the USDA system, so the mountains and the Eastern Shore sit at opposite ends of the window.

Which Spring Bulbs Do Best in Maryland?
Winters here are cold enough to flower every common spring bulb, and the soil suits all of them. What separates one bulb from another is who else wants to eat it. Voles, squirrels, rabbits and deer all visit Maryland yards.
Daffodils come out ahead for that reason. Bulbs that animals avoid will outlast bulbs they dig up.
| Bulb type | How it does in Maryland | Why |
|---|---|---|
| Daffodils | Reliable, returns year after year | Hardy perennial bulb that deer and rabbits leave alone |
| Tulips | Often short-lived | Voles, squirrels, rabbits and deer eat them |
| Crocus | Needs protection | Animals dig and eat the corms |
| Hyacinths | Good where deer or squirrels visit | Animals tend to pass them by |
| Alliums | Good where deer or squirrels visit | Animals tend to pass them by |
Fritillaria and scilla are two more bulbs that Maryland gardeners with deer or squirrels can try. Tulips are still worth planting for their color. Plan to replace them regularly, and treat daffodils as the lasting backbone of the bed.
When to Plant, Chill and Care for Spring Bulbs in Maryland
Planting is the one job with a firm calendar. Timing follows the soil, so a warm autumn pushes planting later and a cool one lets you start earlier. Bulbs planted too soon sprout in fall, and bulbs planted too late have little time to root before the ground freezes.
| Task | Best timing in Maryland | Why then |
|---|---|---|
| Plant | October, or mid-September to late November depending on how fast the soil cools | The soil has cooled off enough that roots can form before the freeze without any top growth starting. |
| Chill in the refrigerator | Not needed | Maryland winters give bulbs the cold they need |
| Remove faded flowers | Soon after the bloom fades | The plant stops spending energy on seed |
| Leave the leaves | While they are green, until they turn yellow and then brown | The leaves feed the bulb for next year’s flowers |
Bloom runs from March through May, and February is possible for the first flowers in a mild year. Tulips and daffodils take the middle of that stretch.
How Bulb Planting Time Changes Across Maryland
Maryland’s land runs from mountain ridges to flat coast, and the soil cools on a different schedule in each.
- Western Maryland: Garrett and Allegany counties are mountainous and run weeks later in spring, so autumn cold also arrives sooner. Aim for the early part of the planting window here.
- Eastern Shore: The Shore runs milder, and the soil takes longer to cool. Plant toward the later part of the window, and keep going into November if the weather stays warm.
In between, follow the soil rather than the date on the calendar.
Where to Get Bulb Advice in Maryland
For a question about a bulb that failed, or about a bed that stays wet, University of Maryland Extension and your county office are the places to ask.
- The state extension site has Maryland-specific bulb articles, and it is a good first stop before ordering in late summer.
- Your county extension office can run a soil test and help diagnose a bed where bulbs keep disappearing, and early fall is a good time to ask.
- Before planting day, check the soil with a thermometer and wait until it has cooled off, reading comfortably cool rather than mild.
Common Questions
Do Daffodils Come Back Every Year in Maryland?
Yes. Daffodils are hardy perennial bulbs that return year after year, and they never have to be dug up. Leave a clump alone and it spreads, which makes daffodils good for naturalizing across a lawn edge or a slope.
What If Bulbs Are Still in the Bag After November?
Plant them anyway. A bulb sitting in the bag does better in the ground than stored over the winter, so keep planting as long as you can dig.
Do Alliums Need a Cold Period Before They Bloom?
No. According to Iowa State University Extension, alliums need a chill period to bloom, like other spring bulbs. They bloom at the end of the spring bulb season, after most others have faded.
