Pumpkins, as well as other plants such as tomatoes, peppers and corn, will not produce pollen if it is too hot. When temperatures rise into the upper 80s, poor pumpkin pollination is often the result. If the temperatures rise into the 90s, you might as well forget about pollination all together. Poor pollination results in low fruit yield, so the less pollination you get, the less pumpkins you’ll have come autumn.
So, as the climate changes, getting warmer earlier in the year, it is quite possible that your local pumpkin patch will have smaller yields and those farms in the warmest areas may need to switch to other crops.
Just some food for thought.
