Blossom end rot is a common issue when growing zucchini (squash), as well as tomatoes, and yes, this is due to a calcium deficiency. The best way to add calcium to your garden is with compost, as most compost is fairly rich in calcium (which the addition of lime or eggshells to your pile can ensure). You also don't need to worry about over applying calcium, which is another common issue. Another approach to adding calcium is to find an organic calcium foliar spray that you can spray directly on the plants (follow the directions). Generally, you only need to add calcium on an as needed basis.

Marrow End Rot

My marrows and courgettes grow to about 4 inchesthen suffer from end rot, those that do survive will not grow any bigger than 5inches I always polinate them but this does not make any difference .the soil PH is 7. 0

Mystery Squash/Zucchini

I have a plant growing in my garden that I did not plant. I think it came from a pack of bird seed. When I first saw it, I thought it was a courgette, but then it started trailing along the ground and now has climbed up my fence. It is very big and has big yellow flowers and a round fruit, but the flowers keep dying and then the ‘fruit’ rots and drops off when it gets to the size of a golf ball. Do you have any ideas?

It is most likely a pumpkin. They frequently become volunteer plants due to their use at Halloween. The birds eat the discarded seeds from the trash and sometimes drop them as they are flying or a pumpkin ends up in the compost pile and a seed survives and is "planted" when the compost is spread. The fruit rotting and dropping off is likely due to poor pollination.
