The first several pics are of the roses themselves and up close pics of the damage. You can see bugs on one of the pics, but that is not on the worst plant (pictured first). The final pic is a Belinda's Dream Rose that's also a month old but doesn't look so good. The entire bed gets 8 hours of sun, or more, and the Belinda's Dream Rose is closer to 10.

Thanks so much in advance!

I manually water 1-2 times a week, but can't really give you a volume of water. I manually water about 10-15 seconds a plant, and then they also get watered with the once weekly lawn water. So a total of 2-3 times a week.

They look a little sunburnt to me, but relatively okay otherwise. Best to stick your fingers around in the soil and see if it is moist enough. If the soil feels cool to your fingers, then there is some moisture in the soil (not necessarily enough, but some). At the same time, don't drown them (soil is pure mud).

Some of those seem planted a little close to the home. A rose can get 5 or 6 feet wide--my Belinda's Dreams are wider than that. If a plant gets 6 feet wide, then it needs to be planted at least 3 feet from the house--more being better, so a person can get between it and the house if necessary for maintenance to the home (or plant).

I would hold off on fertilizer until the plants are a little more established, since they are a bit toasted. Your weather is already warm, which can be stressful for a small young plant trying to establish itself. If the temperatures really shoot up in the next few weeks, some temporary shade will reduce stress.
