Liza, do you have ordinary garden compost? In spite of miracle grows add campaign the very best thing you can add to your garden is compost, not miracle grow. Not saying miracle grow is a bad thing but not as great as it's claimed to be. Your rose is already going to be stressed from two moves. Too much fertilizer is a bad thing in these cases. Compost on the other hand enriches the soil naturally and never burns plants. It increases bad drainage issues and keeps soil that it to dry from drying out as fast. It averages soil acidity or alkalinity. In effect it just always makes the soil better for planting.
And that is for veggies, flowers, shrubs you name it. Compost is a gardeners best friend.
