Butternut squash leaves yellowing
Comments (1)Mine started turning yellow when I transplanted them, so I suspected heat stress or lack of water....See MoreSummer Squash (yellow zucchini) female flowers browning and dying
Comments (8)Hi Gardenerenthusiast, I am glad you asked this question because the same thing has been happening to me, on both my zucchinis and my spaghetti squashes. Along with rotting blossoms that don't open, I've been getting female blossoms where the squash has shrivelled up before the flower even opens. My plants are otherwise healthy, though I have just started to see some yellowing on the leaves. Unfortunately I have no idea what is causing this, though I've narrowed it down to blossom end rot (which would mean a lack of calcium in the soil) or under watering (it's been very dry here and I've been watering shallowly and regularly, instead of deeply), or some kind of virus/fungus etc. I can't see any trace of pests on my plants, save for a few black aphids, and there are no signs of squash vine borers. One of the strange things is that it suddenly affected my zucchini, spaghetti squashes, and now my delicata squashes all around the same time, even though they are in different garden beds. This makes me think it is either the weather or a virus. My current theory is that I haven't watered them deeply enough, and also that they might need more plant food since they are quite close together and fruiting heavily. Sorry I don't have an answer for you, but I would be curious to know if any of that sounds familiar to you. Good luck!...See Moremelons and squash-fruit turns yellow and falls off
Comments (3)Lack of pollination. But you can be the "bee." Just move the pollen from a male blossom (never has a small fruit under it) onto the sticky peg in the center of the female flowers (the ones with the "baby" fruits from day one)....See MoreSquash and Cucumbers turning yellow
Comments (13)I'm in Toronto. I had similar issues with my zucchini (and now starting to with my cucumbers). I tried milk solution. I tried baking soda solution. I think that I was too late with the PM control. My Zucks stopped producing viable fruit. They would still produce female flowers but the fruit would just turn yellow, mushy and die off. So I decided to rip them out, and use the space for fall planting (some beans, peas, radishes). Lesson learned for next year: start spraying the squash leaves at the first sign of PM. There are several recipes you can find online using milk, baking soda, etc. Some people just spray the leaves down with water in the early morning and that removes the mildew. I did not try that myself....See Morecalliope
