This year I have grown a magnificent rockmellon bush. At first I did not realise it was a rockmellon and ate several of the fruit while they were small and green, thinking they wer some sort of warped cucumber (didn't tast too bad) - but that's another story. Unfortunatelly the caterpillers have gone bullistic on leaves and fruit. It is heart wrenching to see my large fruit being eaten before my eyes while I am waiting ofr it to ripen. As quickly at a kill the catterpillers, more find the fruit. Any suggestions for good home made organic sprays or other solutions to this problem. I have used pyrethrum a couple of times - but it is pretty ineffective and the amount required to cover the leaves means that this is pretty expensive. Also I don't want to kill the good bugs. On another topic, has anyone successfuly grown pyrethrum daisies and made their own pyrethrum spray?
