@RoseBlush1 You have been super-helpful!!!
You did say that you can't over-water roses if they have good drainage, but I was still worried about whether or not I actually do have good drainage. However, only a fool would pass up advice from the wiser, and I maybe a fool, but not today.
I'll give them each two cans of water this evening (my watering can is ~1.25gal.), and water a bit more of a broader area to encourage a better spread of the root growth.
Mike said: An important question is, how large are the holes that you dug and replaced with the amended soil?..
I dug a 2'x2'x2' hole of course! I'm no mellenial, I'm a Gen-X'er! I believe hard work & perspiration is the only way to get things done! ...yeah, and turns out that hole was in the wrong spot, and it took me all day, and my hip hurt, and my hands hurt, and... digging is hard.
So when I finally dug holes in the correct places, they were dug with post hole diggers to ~18" deep. My only (admittedly mediocre) excuse is, that when I'm not buying $10 grafted roses in "body-bags" from Waldo's, I'll get the right equipment first.
One day I hope to have Nacogdoches Yellows, & a classic Peace, but I'll do my best with what I've got for now, and hopefully, by the time I'm ready to level-up to those beauties, I'll have enough experience to know how to show them some real care.
As things are, I'm having fun trying to figure this stuff out with a big help from this forum. I almost feel like my little rose bushes are a part of a group effort now, and I'm not only grateful, but I'm also having a good time learning from y'all.
