Sunflowers, do they like lots of water or on the dry side ?

I have grown flowers for years, but this year I am using my digital camera every 24 hours as the blossom opens on my 3 ft. sunflower for a kids' lesson in growth. Do they like lots of water to help them bloom or more dry ? thanks sunflower lovers

I never water my sunflowers. Just make sure you are removing the dead leaves, so the blooms will be nice and full.
Reply:dont let them dry out....... even water is best
Reply:about half and half not too wet but certainly not too dry i suppose a happy medium
