It rained for a full week!! I was glad to have held my nerve and kept watering from the tank --the tank filled in less than an hour (nearly 10,000 litres!!) ----but the mound took several days before it became wet inside. But everything became too wet ------the new zucchinis became water-logged and developed a soggy spot at the end then collapsed -sounds like 'blossom rot'. I picked all the rotten ones and new flowers are already developing.
