Thanks, this makes sense! I wondered because when the zucchini produce fruit, I don't see any dying off and was wondering why the pumpkin did.

Right, I'm not looking for a bumper crop of pumpkins. It's just for fun and if I get a few, I'm happy I'm growing Cinderella and have a biggie already (it's very yellow). Also growing a volunteer from last year which has a good sized one too, green. Interesting color difference. No chance of burying stems. The plants are growing down an alley and a walkway--no room in the actual garden.

Thanks again for the reply.
