Climate matters. This page is a practical baseline. Confirm cultivar, local frost/heat conditions, mature size and regional restrictions before planting.

Growing directions
Plant bulbs in fall at a depth of 3 times the bulb's height (typically 6–8 in) in well-drained soil with the pointed end up. Daffodils naturalize readily and multiply over time; deer and rodents avoid them because the bulbs are mildly toxic. Allow foliage to yellow and die back naturally — at least 6 weeks — so the bulb can store energy for next year's bloom. Divide congested clumps every 5–7 years when flowering diminishes.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
