Growing Zucchini

Well our zucchinis have been looking a bit sad lately, I wonder if its because I haven't been watering them enough? We've been fertilising them fortnightly with a seaweed solution, so perhaps that is enough? When I went out there this morning I discovered a beautiful zucchini flower in full bloom, and two baby zucchinis on another plant so maybe they aren't doing too badly? I've got the sprinkler on them at the moment so they can get a good soaking!
