Succession Planting Charts for Flowers
Use these general guidelines to succession-plant cut flowers at 7-day and 14-day intervals.
- These intervals assume standard growing methods.
- Season extension can let you plant and harvest earlier and later than the usual windows shown below.
- You can also adjust the time between plantings in some situations.
7-Day Intervals
| CROP | PLANTING RECOMMENDATIONS | NOTES |
| Larkspur | Sow in early spring, or in fall for flowers the next year. | Needs a long cool spell to bloom. |
| Sunflowers | Set out transplants first for early flowers, then follow with direct-sown plantings that bloom later. | Choose single-stemmed varieties that mature at different times, and sow several times to keep good-quality blooms coming. For three schedules, see sunflower succession planting programs. |
