Why are my zucchini rotting?
On zucchini and other summer squash, the blossom end of the fruit begins to rot and within a short time the entire fruit has rotted. Blossom-end rot is caused by a lack of calcium in the developing fruit. In most cases, there is no need to apply calcium to the soil.
Why are the tips of my zucchini turning yellow?
Zucchini Turning Yellow And Rotting Blossom End Rot
It is caused by a lack of calcium in the fruit and the reasons are not always due to soil deficiency. Calcium holds the cell walls of plants together and calcium deficiency results in stunted growth, misshapened leaves and yellow, rotting fruit.
