Inherited Rose Fertiliser

Lyn Plant-Wells · July 2016

I have terrible black-spot on most of my roses - some of which were taken out of containers and planted in the borders when I moved to my present house last year. Established roses also affected. My ground is quite sandy - I live near the south coast.

I have inherited some Rose Plus (coarse white powder) not in original container so I have no idea how much to use or correct way of using it. Monty Don says keep roses fertilised and healthy to withstand diseases. I also have Miracle Gro and a bucket of evil smelling green pond sludge from when the pond was emptied after garden makeover. I do have Rose Clear and Fungus Fighter, and sprayed the roses on my return from holiday last month. Does spraying the ground around the roses with fungicide help at all?

I am a novice gardener, as I expect you have gathered!

Incidentally, one of my perennials has what looks like yellow rust on the leaves (pink flowers/large clover shape leaves.) and some of my Vinca has yellowing leaves speckled with black. Are these things related? Thanks for your help. Don't know what I'd do without these Forums!

I moved just before the lockdown and inherited virtually no flower beds, and have brought several roses with me. They have developed black spot on the leaves which then drop off. The roses look very sick. Which is the best fertiliser to plant them in when I can did new beds. I really want to save these roses as they hold many memories. Can anyone help. Anita

When did you dig these roses up? Did you then pot them in soil or lightweight compost? How old were the roses? If they are in pots now, then any rose fertiliser or even something like miracle grow or phostrogen will do.
