Black eyed Susan’s Plant collapsing

Asked July 22, 2019, 5:15 PM EDT

Why does my black eyed Susan plant collapse in the middle and make a hole? It falls outside and the middle is open.

Black eyed Susan, Rudbeckia hirta will topple over if they become too lush from heavy rainfall or too much fertilization. Leggy plants that are in flower often topple over from rain or wind. They can be grown with a structure to support them or with wires. Reducing size of this clump can allow more light to the interior and more leaf retention in the middle and less top heavy plants that blow over very easily. Pinching plants back early as they grow can reduce the height and provide more branching and less top heavy plants. This will push back the flower time.
