Answer: Perhaps nothing. Often mini-roses come from perfect greenhouse growing conditions, get moved to a store, and then to our homes, which have less than perfect growing conditions. These transitions can be a shock to the plant. Mini-roses require sunlight and regular moisture. Make sure water penetrates through the entire root zone and isn't just running out the sides of the pot. When the top inch of soil is dry, water, but don't let the roots sit in overly wet soil. If your roses come back, apply a balanced fertilizer, such as 10-10-10 or a rose fertilizer. But don't fertilize now, as fertilizer "forces" them to grow, which can be stressful since they are not healthy. I hope this info helps.
