no blooms on knockout roses

Question

I bought two cherry red bushes this past spring at Costco. I planted them in good soil, in a sunny spot. They are very healthy and disease-free – no small feat here in humid Baltimore. However, they only have, at most, one or two blooms. What gives? jane

Answer 1

There are a few reasons why any rosebush may not bloom well or at all. We need to be sure their root zone is happy in their new home and 9 times out of 10 the top part will follow along happily.
