How long does it stay warm? 65 at Halloween means it could be what- still in the 50s in December? When you you get a heavy frost?
Onions, gr. onions, carrots, celery, bok choy, potatos, pea pods, all herbs, lettuces...all do well in 65 degree weather.
I personally think anything from the cabage family (broc. cali. cabbage) does even better with a 50 degree climate or less.
Double check your packages to see how many days until harvest any item takes and judge if your weather will hold out. Some items are much quicker crops then others, duh.......
Luck you.....we can hardly grow some items because our seasons change temp.s so fast.
