I read in a prior post, that it was ok to mulch with fresh horse manure. Since I have an endless supply, I've started mulching monthly.

A little early to tell, but leaf growth looks superb. Wondering if the manure is sufficient for fertilizer, or if the roses should be further supplemented?

Also - curious if generally you seasoned gardeners fertilized everything at the same time you fertilize your roses, or were diligent about fertilizing each type of plant to its individual specifications?
