Question

Yes they are in full sun. Yes they appear to be in good health. On I can not see anything wrong with them. I did not deadhead because it says you don't have to do that. And they are being feed. Any suggestions?

Answer 2

Prunig roses is most important to get new blooms.

Deadhead them.

Answer 3

I think you should prune them because it stimulates flowers and overall growth. I think your feeding them too much nitrogen. that gives them nice green leaves and their happy but it doesn't help with flowers. Buy a fertilizer that has a high phosphorus content in it. It helps promote flowers. Or just use a rose fertilizer sold anywhere lol.
