I'm attaching some photos of my backyard. I planted around the border to get some privacy, but as you can see, the ones at the right side are growing out of control and the left and middle need some help!
I suspect the grass fertilizer leaked there hence the huge stems and no flowers.
Nitrogen supposedly makes the greens big and little flowers.
I planted from seed, the pink, purple and white mix.
(It's my first year planting and I made the mistake of overseeding so they are very close together)
I really want to get the other side growing and give it a boost!
