How much fertilizer
I went out and bought Kelp meal, Alfalfa meal, fish bone meal, and Blood meal. Mainly these were bought for the vegetable garden but I also will be using them with my roses. I know you'll say I need to get a soil test, but I have not done that. But how much of each fertilizer should I use per rose plant. These are roses that have been here since the 60's. They did get compost added late summer/fall and I just took the mulched leaves off the bed so I can add the fertilizer.
