how do i know if my 1 of my courgette plants has a disease? and if they are do i need to remove the whole plant  as  there are courgette plants on either side of it.  the courgettes on the plants  seem to only grow a couple of inches then they stop  and they a bit mouldy at the tip....

Panic not queenb.  This rotting off is due to those courgettes not having been fertilized (you know, the birds and the bees stuff)!  You can go around and polinate the flowers carrying the pollen from 'A' to 'B',  A bunny tail is excellent for this.

The mouldy corgettes are still edible, just cut off the mouldy bit.     Cheers,    Tony.

Not sure the bunny would agree with you though Kleftiwallah!

Just rip the male flower off, tear off it's petals and stuff it straight into the female flower.

The males like it rough before a premature death!
