Different pumpkin types take different times to grow but most take over a month to fully ripen and you often wont see any finished products until mid or late March. It is definitely not time to give up yet. Good things to those who wait :) The plants will die very rapidly after the temperature drops in April and May. However if your getting mildew on the leaves in mid Feb I would recommend that you prune or spray the affected leaves to reduce the spread. I have had years where the plant died in late Feb before the pumpkins fully matured and I was very sad.
