The best fertilizer is the one that addresses your existing soil's needs. That being said, few gardeners go to the trouble of using their county extension office or other labs to test their soil's nutrient composition. Even fewer gardeners mix their own soil to replace what they dig out of the ground. When I dig a large hole for a rose, I often mix one-third of what I dig out of the ground (native soil) with one-third peat moss and one-third composted manure, add a cup of Epsoma organic fertilizers (e.g., Rosetone, Gardentone, etc.), and use that to replace what I dug out of the ground when planting the rose.

As for fertilizing established roses, I try to avoid full strength synthetic fertilizers because the salts that are used as the medium to deliver the fertilizer don't do your soil or the earthworms any good, and can build up over time. So I use a combination of diluted synthetic fertilizers, and Bill's Perfect Fertilizer, which is one of the strongest organic-based fertilizers I've ever come across. My roses have never been bigger or more floriferous.

Preparing the flower beds prior to planting I use Espoma Land & Sea Compost and Black Cow soil mixed into the native soil. I also use Espoma BioTone when I plant anything. Actually, I also use Miracle Grow as a foliar feed for some of my plants. So, I use what works for me in my garden.

The big three nutrients required by most plants (including roses) are Nitrogen (N), Phosphorus (P) and Potassium (K). These are the three letters you see on fertilizer packages, and are also referred to as the N-P-K ratio; a fertilizer containing all three would be best. Following this you have 2 options, inorganic or organic fertilizers, in my opinion, the best fertilizer for knockout roses; now this is fully dependent on your own personal views; organic fertilizers are usually byproducts of things like alfalfa, bone meal, fish fertilizer, kelp extract etc.

Once I found Rosetone by Espoma, I haven't used anything else.,

Thank you, Lynda. It appears that there are a lot of fans of Rosetone here on this forum. Are you the Lynda Horn who writes articles for the ARS magazine?

Really! I have a twin out there! Nope, not me. I'm no expert in roses, I can barely keep up with the blackspot on mine! They look beautiful in the spring and horrible the rest of the year. Hilarious!
I keep them for those few glorious spring months.

There is a horse stable for Central Park carriage horses on the other side of the park where I garden. I've given passing thought to asking them for a couple of wheelbarrow loads of manure that I could put in my garden. However, this stuff is fresh; it steams as it is loaded on the truck that carts it away. I don't want to burn the roses' roots. I think I should spread it out over the winter someplace to neutralize it. That would be rather difficult in my circumstances. It's a conundrum: the horse stable ships out tons and tons of manure each week, but I can't make use of it. because it needs airing out. Any suggestions?

Do you have a spot where you can just dump a pile of it and just turn it best you can throughout winter? It will calm down even if just sitting in a pile if you leave it sitting over winter.

Gertrude Jeckll felt that fresh horse manure was a magic potion for roses as it contributed the proper micro-organisms to the soil. I use it all the time, and it never burns anything - just don't pile it up next to the canes.

My British grandfather said the same thing. His life world have overlapped with Gertrude's.
For me, gardening is really just an excuse for playing in the dirt. Admittedly, plants are a satisfying by-product.

I can put it behind the garden I guess. When they chuck it out, it's in the straw that they put down.
Rookie question: can I just shovel the straw and the manure altogether into a wheel barrow and then into the garden? Full disclosure: I haven't even seen horse manure up close for 60 years and I was 14 at the time.

I've seen them shoveling the straw and manure into an enormous funnel that guides it down into a truck the size of an open tractor-trailer. They do it really early in the morning during my dog's first walk. It's a lovely smell.

The straw will take a while to decompose, meanwhile it is mulch!
