I'm doing something a little different this year. In the past I would have never gave any fertilizer to the plants at pollination time, but this year I'm trying to read the plants and just give them what they need. Maybe a little riskier, but I think it could yield better results. This evening I did a foliar application of fish with a little TKO and RAW Yucca in it. Both quantities were small (1 tsp of each) so I'm hoping it will just nudge the pumpkins along rather than abort them.
Temperatures in Denver were nice today but it is going to be 95 degrees tomorrow. Will be putting down extra water for that. Unfortunately the well was down today so I can only do overhead sprinkling right now which isn't ideal because you end up with big dry areas because the big pumpkin leaves act like umbrellas so the watering is very uneven.
