Mike May I ask what part of the Hill country in the West.
A general area will suffice.
The reason I ask is because I live in the hill country also but south east of Austin about 30 miles.
This can make a difference on plant out time by about one to two weeks if you live out around Llano or Marble Falls.
You know what I mean.
As was said as early as you can, start seeds in December and try to plant out in March.
Get your bloom set grow the tomatoes and pull the darn things when the last one is picked.
This should be ending in July.
Then go back and plant Okra in its place.
