Why are my zucchini dying off so early?

I think you have a pollination problem. Roughly half the flowers just wither away to nothing because they are male flowers, and unless you pick them and stuff them, that's all they ever do. I can't ...

Do my zucchini have a chance?

How to stop my courgettes (zucchini) rotting?

Zucchini flowers not opening up any longer

Because they have served their purpose. As you can see, the fruit is already half-grown, which means that the flower end is no longer needed for the fertilization of the seeds. It will fall off soon,...

Why my zuccinies have turned like this?

Given where you live, this seems like a silly question, but are your plants receiving 5 or 6 hours of full sun a day? I think this is a pollination problem, and lack of sunlight can cause that because ...

How do I tell the difference between fungus and natural coloration in zucchini?

The mildew that affects many squash plants grows on the surface, and can be scraped off. The white patches you show, which are exhibited by many squash varieties, are internal to the leaf tissue.

Squash/zucchini plants flowering way too soon

You can pinch off the flower buds until you're ready to plant outside. I don't recommend changing light and heat at this point because it can make seedlings leggy and weak. How much longer do you plan ...

Maybe just patient with them, as it takes a couple weeks for transplants to stabilise; the way they were planted matters too. If the roots were sort of loosened, then they should be ok, as long as ...
