Roses don't grow well indoors, as mike_rivers said. These roses are intended to be more like a cut flower--they bloom and then you throw them out. Now, that's not what we usually do with them, but that's the idea behind plants like this. They are green house grown very quckly to a small uniform size, fed heavily to make them bloom, and then sold at the supermarket or big box store as gifts. It's not that you are doing anything wrong, its that they have had absolutely perfect controlled temperature, humidity, lighting, water, fertilizer, and pesticides to make them look perfect. Now they are in the real world and they are having to deal with it for the first time in their little lives. You can plant them in a pot outdoors (there are often 4-6 individual plants in the single container) or in the ground. They won't survive indoors. They may or may not be good in the garden--some are very good, others are terrible.

For certain, the rugosa is showing iron deficiency. As others have said, it can be caused by waterlogging. However, from the porous look of the potting soil, I doubt the pot is subject to waterlogging. The other cause of iron deficiency is high pH. Rugosas want acid soil, preferably 5.5-6.5. You could treat the pot (soil NOT foliage) with an iron product. If your garden soil is neutral or alkaline, before planting, adjust the pH according to a soil test using garden sulfur or micronized sulfur. This is more effective than iron supplements, but it takes a year to work.

That makes me feel somewhat better. I had fears about planting so late in such hot weather but my excitement got the better of me and I just couldn't wait until the fall to purchase and plant. The rose is nice and cool on my covered patio area and I have watered it well this morning. Hopefully I can keep it alive for the rest of the growing season. Thanks for the reply!

Thank you all for your input! I told my mom about the watering and the shade and she said she'll do it. Karen, the rose is new. We got it this year. But it grew like crazy and was blooming in no time. My mom was actually a little surprised. The TZ was growing and blooming better than some of our older roses. My apologies for the pictures. I'm not the best photographer. As for the soil drying out in between waterings, I wasn't quite as clear as I should've been. I typed this post after several hours of mind-numbing calculus homework (I'm not the best at math). Anyways, they don't wait for it to be 100% dry before watering again. My apologies for not being clear about that. I think I might go back and edit my original post to fix that. They water them in the early evening. We have a lot of mosquitos because of a retention pond that's really close to our house so my parents try to get out and water them before Our roses were fine last summer so that's why we're a little perplexed. Only the TZ is unhappy. All of our roses get the same amount of sun and the same watering schedule but four out of five are doing great. Two of them seem like they might have gone dormant or something like that but they still look happy and healthy. Is the TZ a more...sensitive kind of rose? I don't know if that's necessarily the right word, but it's the only one that I can come up with at the moment. Thanks again for the help. I really appreciate it!
