Depends on where you have your rose. Are you keeping it inside? Roses do not like to be inside unless you have very sophisticated lighting and moisture control. Now if you do have your rose outside and the leaves are turning yellow it could be just normal depending on how many leaves are yellow. roses shed older leaves all the time which is normal or it could just be the climate change. Most roses people ask about are "store bought" roses and they are grown in greenhouses and then sold to stores where they are kept inside. This requires them to be "hardened off" which means to put them outside in semi shade for a few hours everyday for a week or so and then they can be left outside. These "Store Bought" mini roses are hard to kill if treated properly and planted outside in the ground or even in a big pot (12" or larger). Good luck and Happy Gardening! Ms.Mary

What did you use for the Aphids? Leaves turn yellow, exhibit chlorosis, for many reasons and sometimes people spray inappropriate things on plants to eliminate Aphids that cause the plants leaves to die, which yours are doing. If something was sprayed on those leaves that restricted that leafs ability to breath or photosynthesize the plant will cut off nutrient flow to that leaf and it will die.

Somewhere here on GardenWeb is a document describing in detail how to keep a miniature rose in reasonably good health indoors, but I can't quite locate it. If any of you remembers where to find it, please include a link. QZ: It is almost certain that the leaf yellowing you are seeing is a result of multiple stressors the rose is experiencing in your home. That's not your fault - its simply a fact that the rose was grown in a greenhouse, and is now faced with trying to acclimate to dramatically different conditions (IE: lower light levels, much dryer air, etc). Now, its not impossible to keep the plant in good health in the home, but there are several challenges that need to be overcome. Most importantly is the light intensity issue: on the average winter windowsill, roses are getting a small fraction of their optimal light levels. This alone can result in dramatic leaf loss. The only remedy for this is to supply additional lighting. Commonly, people use compact fluorescent bulbs, or (these days) LED plant lights. If you are just lighting one small plant then you can likely get away with buying a single bulb that can be used in a standard light fixture. Some of the smaller plant lights are quite inexpensive and come as an all-in-one fixture + bulb configuration. At this point, you have to decide if you want to invest in the technology for a single plant. Only you can make that assessment. A cool windowsill isn't necessarily the worst thing for a miniature rose. As long as the leaves don't freeze, and as long as daytime temps are at least 65F or warmer, you're in the acceptable zone. A major obstacle to rose growing indoors is insect pests. The worst/most common are Spider Mites. It is almost inevitable that you will get Spider Mites on the undersides of the rose leaves, so you need to be ready to deal with that. (You can Google "spider mite damage on roses" or similar, to find photo examples of the issue) Spider Mites love hot, dry air, so if you can maintain some humidity where the plat is, you'll have less of a battle on your hands. Your best (and cheapest) weapon against Spider Mites is water: simply take the plant to the sink once or twice a week and hose off the undersides of the leaves with a strong spray of water. Mites hate water and they are easily washed off, so if you wash the plant regularly, you can potentially avoid the Mite problem entirely. Its easier to avoid insect problems than fix them once they've happened. The HGTV article linked here is a brief-but-reasonable document that explains much of the same info in greater detail: https://www.hgtv.com/outdoors/flowers-and-plants/trees-and-shrubs/grow-a-miniature-rose-indoors I expect you will find that the rose will continue to drop yellowed leaves over the next few week. It may in fact lose all its foliage. That's not unheard of as the plant goes into a semi-dormant state, sensing that its light source has diminished to unsustainable levels. If you should find yourself with few or no leaves left, its a good practice to cut the plant down to about half its current height. Given time, it will make new growth, so it might as well start with strong new growth from close to the base of the plant. Cutting it down helps facilitate that. Also, be more sparing with water if the plant does drop most/all of its foliage. A leafless roses doesn't need a lot of water: just enough to keep the soil barely damp to the touch is sufficient. That might mean watering once a week or less. When the rose does decide to resume growth, it will need more water, which you will figure out pretty quickly by observation. Adding a strong light source will encourage new growth also. Now, it is true that these miniature roses are sold as gift plants, and are considered in the industry to be "disposable" gift plants - much as we regard Poinsettias and the like. That doesn't mean you can't keep the rose going, but it will require some effort and careful attention on your part. It really comes down to you to decide how much effort you're willing to make. Best of luck, and feel free to ask questions, should you have any. Paul

@ken_adrian yes most of the yellow leaves are the oldest ones. So no way to avoid that and I should not worry about it? The container mix is 1/3 peat, 1/3 turface, and 1/3 pumice. That is a wet soil but roses seem to like well-drained moisture-retentive soil. In any case, this is just an experiment. So far, this soil is doing the best. The big surprise for me so far has been that 5-1-1 mix has gone nowhere. The plant (identical species from the identical grower) in that soil has not grown at all and looks like it is in shock.
