what is the procedure for germinating rose seeds?
Floyd County Kentucky
From Hartman's "Plant Propagation":
Seed propagation is used in breeding new cultivars and to avoid virus transmission.
As soon as the rose hips are ripe, but before the flesh starts to soften, they should be collected and the seeds extracted. Stratify them immediately at 35-40F for 4-6 months. Hybrid roses usually respond best to stratification temps of 34-40F for 60-90 days. The seeds may be planted either in the spring or fall in beds. Seedlings smaller than 4" by be killed by cold weather.
