Q: I planted several Knock Out roses last year. They bloomed nicely last fall and spring but, unlike my neighbor’s bushes, I don’t see any blooms now.
A: Like all roses, Knock Out blooms occur at the end of a recently produced branch. In my observation, the new branch must be 12″ – 16″ long before flower buds emerge. My guess is that you didn’t fertilize your rose regularly. Regular feeding stimulates new growth throughout the summer, leading to copious blooms from spring until the first hard freeze.
