Q.Butternut Squash Vines
Butternut squash vines went from green and thriving to yellow and droopy in a matter of days. The fruit is dark green but has stopped growing, and no new fruit is developing even though there are lots of bees in the garden. Why would this happen, and is it okay to pick and eat the squash now? The tomatoes and green peppers in the same plot are doing well.
