For this reason, most gardeners prefer to grow roses from cuttings. The task of growing roses from seeds is very involved. Heirloom rose varieties grow true to the parent plants, while hybrid varieties are less predictable. Without proper stratification, it can take multiple years for seedlings to emerge.Įven the fastest-growing roses will likely take two full growing seasons to produce beautiful blooms. Growing roses from seeds is a lengthy process. How long does it take to grow a rose from seed.Use a high-quality blend like Dry Fertilizer for guaranteed results.

Add one-half tablespoon of 3% hydrogen peroxide to one cup of water and soak the seeds in this solution for an hour. To prevent fungus spores from growing, you can destroy them with hydrogen peroxide. If you aren’t careful, this extended moist storage can lead to the growth of molds that can threaten young rose seedlings. Rose seeds need a much longer germination period than many flowers.
