This is my first year gardening. I planted sugar pumpkins and the vine is enormous! The problem is I'm getting blossoms, but no pumpkins. What's going on?

This could be due to poor pollination. Poor pollination affects fruit set. High temperatures will cause plant stress. As a result, any pollinated fruit may have simply aborted. A heat wave can also deter bees from their job. You could also have more male flowers than females, which also inhibits pollination. You could try hand-pollinating your pumpkins, which is done in the same manner as with squash.
