Planting Flower Seeds

Not Recommended
This table lists the recommended times to sow flower seeds for typical Zones 8-9. If you are in zone 7, for instance, go back a month, zone 6, a month and a half. If you don’t know your zone, check the planting zone maps. And when buying transplants, remember to adjust for the age of the plant (about 1-2 months).
