Propagation by Seed: American red raspberry seeds are best sown in the early autumn in a cold frame. Stored seeds should be stratified for one month at 3ºC. When the seedlings are large enough to handle place them into individual pots and grow them in a cold frame. Plant seedlings in their permanent position in the late spring of the following year.
Propagation by Cuttings: hardwood cuttings can propagate American red raspberry. Cuttings should be propagated in a site out of full sun and sheltered from drying winds (Heuser 1997). A slow release fertilizer should be added to the rooting medium where the cuttings will stay for a year before transplanting.
