Succession Planting Charts for Flowers
Follow these general guidelines for succession-planting flower crops at 7-day and 14-day intervals.
- Take note that the timing intervals listed here are based on standard growing practices.
- Modifications such as season-extension practices can allow growers to plant and harvest earlier and later than the standard date windows suggested below.
- Intervals between plantings can also be modified under certain conditions.
