Is it to late to start okra seeds here in central Florida?
Okra like collard are a hot weather plant that will do well in S.C. heat. I have not planted my okra seeds yet.
I would think you can plant them now, also.
Here is the U of FL gardening schedule for planting dates. Note it is broken down into north, central, and southern Florida schedules. Okra is planted March to July.
Florida AG extension website has all sorts of into on stuff like this.
