I just moved to a new house with about 20 roses, minature and regular size. I have no idea what the names are and am not going to worry about that until next year so hopefully that is not too important. So here is the problem and I am not even sure if it is unusual or not. Some of the plants have clusters of brown/yellow spotted leaves, some of the plants it is just a few clusters but others it is the majority of the bush.
But ALL the plants have wimpy blooms, before the flowers even open all the way the outside petals already wilt. There also seems to be mounds of nasty seed looking mush in the center of many blooms, is that normal? I thought people grew roses for the beautiful, lasting blooms, mine only last maybe 2 days before fading.
Sooo... what is the leaf yellowing? and what's with the mush? and quick fading blooms?
Other info that may be helpful...
When I first moved in a month ago there were no blooms on the plants, since I have fertilized twice and there are tons of blooms. Fertilized with 16-16-16 because that was the recommended fertilizer as they are mixed in with reg plants, edibles, fruit trees etc all in close proximity.
I water 3 times a week, leaves are not drooping, but on a couple plants in full afternoon sun, but after I give them extra water all the leaves perk up.
I am an intermediate gardener, have grown everything from peppers to tropics, inside & outside orchids (have one I am very proud of, has been blooming since before mothers day) bulbs etc. But this is my first time with roses, not to fond of things that bite back when I prune them :(
Sun widely varies to just morning sun- full afternoon sun.
Located South Bay Area.
Have not seen any bad bugs, a few grasshoppers and green ladybugs, plenty of butterflies and hummingbirds, none of those I believe are bad?
Sorry no pics. Let me know if more info is needed
