If you also want to have beautiful annuals, here are the quick steps to success. Note that in photo 1, the flowers are even from the top of the basket to the sides, nice and proportional. In photo 2 and 3, they have grown out and gravity has pulled them down and now all the flowers are basically not in the basket but hanging from it.
Here's the why we do photo 4 and 5, cutting them back to the edge of the container. Its July 20 and I just cut mine back for the second time and hope to do it once more in August. If you let them grow another month as they are in 2 and 3, they will keep getting uglier and uglier. This creates a view where the blooms are 2 feet from the container and the container is basically empty.
You probably, as I am, will be tempted to put them out of their misery and dispose of them. The reality is that your annuals should be singing joyfully "look at me, please look!!" until the 3 weeks before frost. Yes, I admit it, plants sing to me, crazy or blessed is up to the beholder.
