Key takeaways
What to know before you act on this, from the SteadScape editors.
- In USDA zones 3 to 5, aim to plant bulbs by mid-October, but you can extend this to late November with proper soil checks.
- Use a soil thermometer to ensure soil 6 inches down is below 60°F before planting; this typically aligns with nighttime lows in the 40s.
- If planting late, cover the area with 2 to 3 inches of mulch to prevent frost heave and protect newly planted bulbs.
- Check the soil's freeze status by pushing a shovel into the ground; if it feels crumbly, you can still plant bulbs.
- For next year, consider mulching with 4 to 6 inches of shredded leaves in late fall to extend your planting window.
