Tulips transform the garden with their spring colors. When planted at the right time, success is ensured. The most important thing is soil temperature when dec­iding when to plant bulbs. Plant when the soil temperature is below 55°F. or 13°C. This will be from the last of September to the end of November. I watch my soil thermometer closely every fall.

Temperature Guidelines

  • Plant when soil is 55°F (13°C) or cooler
  • Use digital thermometer 4 inches deep for accuracy
  • Avoid planting during frost or extreme cold snaps

Regional Variations

  • Northern zones: Early September to October
  • Southern zones: November to December
  • Coastal areas: Adjust for maritime climate effects

Correct timing prevents premature sprouting before winter. It gives the roots a chance to develop without growth above. The bulbs require cold dormancy to bloom in the spring. I've seen bulbs planted all too soon freeze and rot. Those planted late produce weak stems.

Pre-chill bulbs 8 weeks in zones 9-10 before December planting

Notice weather trends each year. Warm spells not in season may delay planting. Heavy rain causes muddy conditions, which damage bulbs. I wait for dry spells with cool temperatures. Get your tools and soil ready and watch the weather conditions. Good timing will give wonderful results in the spring.
