Yellow Leafs On Rose

[Nyboy]

I planted 5 rugosa roses last spring. All made it threw winter, have good growth and are flowering. I notice 2 of the bushes have patches of yellow leafs. Back of my mind yellow leafs mean lack of something. Can not remember what

 

[so lucky]

Do they have black spots on the yellow leaves?

 

[Nyboy]

Don't remember at country house. Rugosa don't get black spot. They are one of the few roses that don't need spraying

 

[flowerbug]
