How to Grow Roses Indoors in Winter

Find a location indoors that has a lot of sunlight during the day. Roses need at least six hours of direct sunlight to thrive; the more sunlight the better. This will determine whether you grow a miniature rose on a sunny window ledge or try raising a full-size rose plant in a sunny room in the house. If you choose to plant a full size rose, select one of the varieties that does not grow very large. When selecting a rose, choose a plant that has a fragrance and is disease and pest-resistant.

Put a layer of Styrofoam packing peanuts in the bottom of the plant container; fill the container about one-third of the way full. These peanuts will allow for adequate drainage for the plant without adding extra weight to the container. Use these peanuts even if the container has a saucer on the bottom.

Make a planting mixture of 1 part peat moss, 1 part mulch and 2 parts potting soil in a bucket. Put this mixture on top of the packing peanuts, filling the container to a little more than halfway to the top. Lightly shake the container to allow the mixture to settle around the peanuts and add more if needed to bring the mixture level back up to half full.

Remove the rose from the container it came in and gently loosen the roots with your fingers. Center it in the new container and add some of the soil mixture around the roots. Water lightly to settle some of the soil. Finish filling the mixture to the point that the bud union is covered with about 1 inch of the soil mixture. Do not water again at this point; it might slosh out when you move the plant container.

Place the container in the sunny spot. Now water the soil gently. Keep the soil moist but not wet. Apply indoor plant food to the rose about once a month. Watch for problems normally associated with roses, such as insects or disease. Treat immediately with a pesticide or fungicide. As the plant begins to grow it will "reach" for the sunlight. Shift the container so a different side of the rose is exposed to the light. Prune and deadhead the rose the same as you do during the spring and summer.
