Planting Times for Spring Bulbs in Zone 8
The best time to plant spring-blooming bulbs in Zone 8 is from October to December. This lets the bulbs grow strong roots in the cool months. They then bloom in late winter to spring. Experts say to plant when soil temperatures are below 60°F (16°C), signaling the bulbs' dormancy period.
Planting too early can stop the bulbs from getting the chill they need to bloom well the next year. The perfect soil temperature for planting is 40-50°F (4-10°C). This helps the bulbs start their root growth, preparing for a great spring bloom.

| Reticulated Iris (Iris reticulata) | 4 inches | 3 inches | 40-50°F | 5-9 |
| Tulips (Tulipa spp.) | at least 6 inches | N/A | N/A | 3-7 (Zones 8-10: late Nov/early Dec) |

In colder areas (Zones 4 to 7), plant spring bulbs when the ground is cool and evening temperatures are 40° to 50°F. Do this at least 6 to 8 weeks before the ground freezes. In warmer areas (Zones 8 to 10), you might need to chill the bulbs in the fridge for 6 to 10 weeks before planting.
Knowing the best planting times and depths for spring bulbs in Zone 8 helps gardeners get a beautiful display of blooms next season.
Chilling Requirements for Spring Bulbs in Zone 8
Gardeners in warm climates like Zone 8 have a special challenge with spring-blooming bulbs. These bulbs, including tulips, daffodils, and crocus, need 10-14 weeks of chilling at 35-45°F (2-7°C). This chilling helps them form flowers and grow roots. Without it, the bulbs might bloom, but the flowers won't be right.
In Zone 8, where winters are mild and frosts are rare, this chilling can't happen naturally. So, gardeners must chill the bulbs themselves, often by keeping them in the fridge. This should start in mid to late October to get them ready for planting in late fall or early winter.
The bulbs in Zone 8 need at least 10 weeks of chilling. Some, like crocus and snowdrops, need about 15 weeks to bloom well. Tulips and daffodils usually need 10 weeks.
Getting the timing and temperature right during chilling is key. Keep bulbs at 35-45°F to stop them from freezing or getting too warm too soon. Also, avoid exposing them to ethylene gas, which some fruits and veggies give off when they ripen. This gas can hurt the bulbs.
By knowing how to chill spring bulbs and doing it right, gardeners in Zone 8 can have beautiful, long-lasting flowers in their gardens.
When to Plant Spring Bulbs in Zone 8
In Zone 8, the best time to plant spring bulbs is from October to December. This lets the bulbs grow strong roots and get the chill they need before blooming in late winter to spring.
Experts say most spring bulbs need 10-14 weeks of chilling at 35-45°F (2-7°C) to bloom well. Without this chill, flowers might be small and not look right. Zone 8 gardeners should chill their bulbs in the fall for the best blooms.
In the warmest parts of Zone 8, some bulbs like big tulips, hyacinths, and crocus might need more chill. Planting these bulbs a bit early in the fall helps make up for missing chill hours.
By planting spring bulbs at the right time and giving them enough chill, gardeners in Zone 8 can enjoy a stunning spring garden.
Summer Blooming Bulbs for Zone 8
