swannsong57, I have decided to plant late gourds too! I don't have any idea if its going to work or not but one thing for sure I'll never know what happens if I don't try!! I'm going to experiment and see just how thick the gourd walls will be at the end of the growing seasson. (If I can even get the seeds up). But the hot weather were having and the enormous size of the grasshoppers are not in our favor. May be some one can answer these questions. Good luck!

According to what I found online, you won't get full grown birdhouse gourds by your frost time.

"Lagenaria, or 'Bird House' gourds will need about 150 to 180 growing days in order to fully mature to 9" or 10" gourds."

That puts your harvest dates somewhere between mid January or mid February.

You can certainly try, but you'll have better luck if you wait until next season and plant in the spring.
