Purple Rose Seeds (Packet of 10)

Stratify your rose seeds to encourage them to grow better. To stratify your seeds, place them on a paper towel that has been soaked in a solution that contains half water and half peroxide to prevent mold from occurring. Fold the towel to keep the seeds inside and then put them all into a resealable bag. Place the bag inside a refrigerator that is set to 34 to 38 degrees Fahrenheit. Keep the seeds in the refrigerator for six to 10 weeks. Another method to stratify is to place the seeds in a tray of potting soil, cover the tray and then place it in the fridge for a few weeks.

Create a potting soil mixture that is ideal for rose-growing by filling pots or trays with half vermiculite and half sterile potting soil. Push the seeds down into the soil about 1 inch. Place them outside in direct sunlight once the threat of frost is gone and water the soil when it looks dry. The seeds will likely begin to sprout in about six weeks.

Transplant the seedlings into separate containers once they have grown a few inches tall. Be careful not to touch the plant's roots during this process. The use of a spoon may be helpful.

Apply fertilizer to the roses after you transplant them. Either buy the variety that can be sprinkled around the plant or the type that can be added to the water. Look for a fertilizer with a ratio of 1-2-1, which indicates more phosphorus in the fertilizer than nitrogen or potassium. The package will tell you exactly how much to apply to the plant, as the amount typically depends on the brand of the fertilizer. Fertilize the bush again in the spring, summer and a few weeks before frost occurs.
