Thanks for the response.

Can I ask a follow-up question?

I have dozens of immature male flowers getting ready to open and no female flowers. The very tiny ones it is hard to tell which kind it is.

Should I snip them all off as soon as I recognize if it is male, or only the ones that are most mature?

This is the fourth year I've grown small sugar pumpkin vines, and I always fail to get fruit. Now it is August and I have a huge vine and again no fruit. Next year I was thinking of trying to grow a different variety, and was considering a more aggressive variety.

I have no idea how to test if I am fertilizing correctly for pumpkin or any of my plants. Most explanations for soil testing confuses me with the data charts and chemical adjustment plans. I usually start with a rich bagged compost for a container plant or worked into the garden soil, then add organic fertilizers, worm castings, and compost tea weekly or so during the season.
