A couple of things. 1. Zucchinis need bees to pollinate or you have to do it by hand ( break off a male flower and peal the flower part back and rub the female flower). 2. You need both male and female flowers to be able to pollinate (sometimes there is all male flowers and sometimes all female flowers - happened to me this year). 3. Wet weather brings moths grubs and disease - water down low around the plants and not on the plant - also if watering the plant do it in the morning so it dries out before night. 3. With the storm season happening it is probably too late for zucchinis now. A thing for blossom end rot is some Epsom Salts - google about doing it - it works for tomatoes. By this time of the year I normally have all my plants harvested - summer too windy, too hot and chance of wrecking storms - like last night - Bundaberg.
