Care for baby roses house plant - need some tips!

Hmmm, could be too much water. Are they in pots with holes for drainage? If not, re-pot them into ones that do, and are also big enough for them to grow. The cute little pots they sell them in only last so long, they become root bound and perish. I do well with Miracle Gro products and can grow almost anything with them. I am working with a Nook and do not know how to insert links, (someone needs to teach me!), and " Thespruce.com" has hybrid tea rose info that is excellent. I would Google and read what all the various Rose Societies have to suggest. They also need to be fed with rose food. Any garden center or home improvement store will have many products to choose from. Hope this helps some. If you can post a photo, I might be able to help you further. 🌹
