Roses (genus Rosa) are perennial flowers that grow as a shrub or vine and do well in most USDA hardiness zones. You can choose from more than 100 varieties, and you can purchase them as a mature bush or grow your own by germinating and planting seeds. Whether you harvest your own seeds from an existing rose bush or purchase the seeds from a nursery, the steps toward germination are the same. Germinating rose seeds is a long, yet rewarding process, but the steps are simple to perform.
Place your rose seeds on one-half of a heavy-duty paper towel to begin stratification. Stratification will help the seeds germinate. Mix ½ cup of water with ½ cup of peroxide. Pour the mixture gently on the paper towel and then fold over to cover the seeds. Put the paper towel inside of a plastic resealable bag. Label the bag with the name of the seed and the current date. Put the bag in a refrigerator for six to 10 weeks at a temperature of at least 38 degrees Fahrenheit.
Remove your germinated seeds from the refrigerator. Fill a nursery flat with a 50/50 mixture of sterile potting soil and vermiculite. Gently press one rose seed into each cup of the nursery flat, going down about ½ inch. Spray the seedlings with a 50/50 mixture of water and peroxide to prevent disease prior to covering them with more soil. Add a light layer of the sterile potting soil and vermiculite.
Mist the planted seeds with plain water using a spray bottle until very moist. Put the nursery flat outside in an area that receives direct sunlight. Keep them moist by spraying with water every day. Within two months, the seedling sprouts will push through the dirt.
Transplant the seedlings to a larger pot when they reach 3 inches in height. As the new rose bush begins to mature and outgrow its pot, you can transfer it to a permanent location that receives four to five hours of sunshine each day. It can take up to three years for the rose bush to reach full maturity.
