    This can happen when watering is not even. Normally you see this when you have a long period of dry heat followed by a sudden large amount water, either from manual watering or a rainfall.

    The plants will be fine and should keep growing.

    Our birds are much nicer and wait, however, I've read where some folks bag the heads of their sunflowers to protect them until full bloom. Stick a brown lunch bag on the head and keep it on with a lose fitting rubber band. (Don't choke the head off.) For birds, it's out of sight. out of mind. ;)

    You may need to be patient, most varieties of sunflowers have a fairly long growth period before maturity. It depends on what variety you planted. I have 2 Maximillians in full bloom and other varieties haven't put out bloom yet.

    Hope that helps,

    I'm puzzled too. It could be that much nitrogen is giving your plants all that green but no flowers, but if the plants look puny, rainwater may be leaching the nutrients away. Add some peat moss to the soil to hold moisture and try foliar feeding.

    You don't mention what kind of annuals but in addition to the answer provided by Nikki, If you have gotten SOME annuals need the spent blossoms removed before they do their best. This is particularly true of marigolds. Petunias should be blooming without deadheading, however, so it sounds like they indeed need some fertilizer. Use one specifically made for flowering plants.
