When to Plant Spring-Flowering Bulbs in Fall: Timing, Depth, and Fertilizing

Bulbs appear in stores by September, but planting too early triggers premature top growth. The sweet spot: late October, when night temperatures consistently drop below 60°F.

Planting Window

• Ideal: Late October–November (soil warm for roots, air cool for dormancy).
• Acceptable: As late as December (less root establishment).
• Depth: Cover bulb top with 2″ of soil—exact depth not critical.

Fertilizing Schedule

1. At planting (fall): 2 cups 10-10-10 per 10 sq ft, worked into bed.
2. Spring emergence (March): Same rate, broadcast over foliage.

Specialty bulb fertilizers avoid fall nitrogen that forces unwanted growth.
