My Zucchini Leaves Are Turning Pale Yellow

Question

The zucchini plants I planted about three weeks back are turing pale yellow. I put lots of tree humus in the soil last year and water them regularly. Do they need more nitrogen fertilizer? I fail to understand.

They may have been improperly acclimated, and are now suffering from sunscald. That being said, you would have seen signs of this within days of planting them out. If this was the case, this article will help you with planting out seedlings in the future:

If they were fine in the week or so after planting, they may be suffering from transplant shock. Increase water to the plant and this article will also help:
