There are several simple requirements needed for planting the seeds of roses. None of those requirements are difficult to find or cost a great deal of money and using them correctly, you should be able to grow a rose from seed. It should be noted that you will not get the same kind of rose you took the seed from. Roses are so hybridized that you may get some of the characteristics from a rose used years ago. You may get a climbing rose from a bush rose or a white rose from a red one.
It is rare to find rose seed for sale. You must gather them yourself and you must start the year before. Rose seeds are found in the hips of the roses. The hips are what are left after a flower dies back and the petals fall off. It is the round ball-like base of the flower. In the fall hips will turn red, orange or yellow depending on the type of rose. Once they are brightly colored they can be cut and split to review the white seeds inside. Some hips have only one seed and some may have many.
The seeds need to go dormant by going into a cold period. The seeds can be placed in a damp paper towel then placed in a resealable sandwich bag, labeled, and put in a refrigerator. The refrigerator should be set at 36 degrees Fahrenheit and no more than 40 degrees Fahrenheit. They can also be placed in damp vermiculite and placed in the sandwich bag and then in the refrigerator. After a minimum of 90 days they can be planted in soil.
Pots and Sterile Soil
The seedlings can be planted in pots or flats filled with sterile soil. Sterile potting soil can be found in large plastic packages at the garden center. It is soil that has been brought to a high enough temperature to kill any weed seed, fungus or bacteria. Seeds in the bags may have sprouted and they may not have. They should all carefully be planted about 1 inch apart. Cover with about 1/8 to 1/4 inch of soil and tamp down gently.
Water and Light
The seedlings will need enough water to keep the soil moist. In order not to flood the seeds a spray bottle should be used. There should be no puddles of water on the surface of the soil root rot may occur. The area in which the pots are stored should be at no less than 60 degrees Fahrenheit. The seeds will do well in moderate light the first month but after that a grow light will be needed to give the seedlings enough light to grow. The light should emulate the amount of sun the plants will get in the summer. Therefore, about eight hours should be sufficient. Some roses three years to get to the size of a rose you would buy at a nursery and some roses do not bloom for two or three years.
