Sometimes, the veins of rose bush leaves will turn yellow. Often, the leaves will then become brown and dry and drop off the plant. Oxygen deficiency causes this in rose bushes, and is often present in plants that have poor drainage and are constantly sitting in soggy soil.
Here are the most common reasons for yellowing leaves: 1  Normal aging. 2  As many plants age, the lower leaves will turn yellow and drop off as a normal part of growth.3  This is especially true of foliage plants like dieffenbachia and dracaena. 4  In this case, don't worry.ellowing leaves can be caused by a number of conditions. If the cause is obvious, you can fix it immediately. If the cause isn't so obvious, try changing one thing at a time until you fix it. Even after you correct the problem, however, it's likely that yellow leaves will fall off with time.
