Herbs, Flowers & Specialty CropsTulip Planting Calendar
Tulips are planted in autumn and bloom in spring after a long cold rest. The timing is tied to cool weather and soil drainage far more than to any date on the calendar.
Key points
- Plant tulips in fall, leaving enough cold weather ahead for 10 to 14 weeks of chill.
- Dig to two to three times the bulb height and test drainage first.
- In warm regions, ask extension about pre-chilling.
- Plan to replace hybrid tulips every couple of years.
When should you plant tulip bulbs?
University of Missouri Extension says spring-blooming bulbs are planted in fall and need about 10 to 14 weeks of cool winter weather to form flower buds, even though they grow roots in the fall. That tells you the real rule: plant early enough for roots to develop, and have enough cold weather ahead for the chill.
Planting too early in warm soil can push premature top growth and invite disease. Many gardeners wait until nights are consistently cool. Ask your county extension office what planting window works in your area, since fall weather varies widely.
Buy bulbs when they first appear in stores, since early selection is best, and store them in a cool, dry, ventilated spot until planting. Never leave them in a closed plastic bag, where they can mold.
What if your winters are too mild?
In warm regions, tulips may not get enough chilling on their own. Gardeners there often refrigerate bulbs for several weeks before planting and treat tulips as annuals. Keep bulbs away from ripening fruit in the refrigerator, because gases from fruit can harm flower buds.
Your extension office can tell you how long to chill bulbs for your area and which tulip types perform best. Do not guess, since too little or too much chilling gives poor bloom.
How deep and how far apart should you plant tulips?
The Missouri guide advises planting bulbs about two to three times as deep as the bulb is tall, which keeps them from pushing out of the soil as roots grow. Space bulbs according to the package, and plant in groups for a better display.
Place bulbs pointed end up and water after planting to settle the soil. Choose plump, firm bulbs, since shriveled ones may be diseased.
- Plant at two to three times the bulb height.
- Set bulbs pointed end up.
- Group bulbs in clusters for impact.
- Water after planting to start roots.
- Choose a spot with spring sun.
- Loosen soil below the bulb so roots can grow.
- Mix in well-decomposed organic matter if drainage is poor.
- Avoid fresh manure against bulbs.
How do you check drainage for tulips?
Drainage decides whether bulbs survive. The Missouri guide suggests digging a hole about 12 inches deep, filling it with water, refilling it and measuring how far the water falls in 15 minutes, then multiplying by four for an hourly rate. About 2 inches an hour is ideal, under 1 inch is poor and over 4 inches is too fast.
To improve drainage, mix in well-decomposed organic material or build a raised bed. Use a soil test and local recommendations for any fertilizer, since nutrient management rules vary by state.
Will tulips come back every year?
Many hybrid tulips decline after the first year or two. The Missouri source notes that tulips often need replanting every couple of years, while daffodils are more reliable. Species and some older types perennialize better.
After bloom, let foliage yellow naturally so the bulb can recharge. Remove spent flower heads, but do not cut leaves early. Cut flower growers often treat tulips as annual crops and replant fresh bulbs each fall.
For a longer show, mix early, mid and late types so bloom runs across several weeks. Check each description to see where it falls.
How do you protect tulips from animals and pests?
Squirrels, voles and deer often target tulips. Barriers such as wire cages, mesh over beds or planting in baskets can help. Bulbs planted deeper, within the guidelines above, are also harder to dig up.
If you consider any repellent or pesticide, the label is the law and applicator licensing varies by state. Ask your extension office for current recommendations and humane options.
- Wire or mesh over the bed can stop digging.
- Plant bulbs with the guidelines on depth.
- Ask extension about local pest pressure.
- Choose humane exclusion over poisons.
What does a tulip calendar look like?
Write down the date you order bulbs, the week soil cools enough to plant in your area, the date you test drainage and the date you plan to chill bulbs if needed. Mark spring for foliage care.
Each year note when bloom started and how long it lasted. Those notes help you pick better dates for next fall.
- Order bulbs early for the best selection.
- Mark your planting week.
- Mark the date to chill bulbs if needed.
- Record bloom dates each spring.
