How to Grow Rose Seeds? A Detailed Guide to the Latest Planting Methods
Roses belong to the order Rosales and originated in China; in Korea they are called haitang flowers. How do you grow roses, and how do you grow rose seeds? Below we introduce the cultivation methods for rose seeds.
The sowing method among rose planting methods is generally used only for breeding new varieties. Place seeds harvested in autumn into a plastic bag filled with moist sandy soil, and keep them in an environment where it freezes at night and thaws during the day. After about 1 month, gradually raise the temperature to around 20°C. Once the seeds crack open and germinate, they can be sown, or they can be stored in sand until sowing the following spring. When the seedlings grow 3-5 small leaves, transplant them.
Soil selection: rose seeds have a relatively low germination rate, so the soil used for sowing generally needs to be loose, breathable, and highly water-retentive. The soil commonly used is a mix of vermiculite, peat, sphagnum moss, perlite, osmund fiber, and the like; if conditions allow, you can also mix your own. If conditions do not allow, ordinary slightly acidic soil will also do, but the soil must contain no foreign objects (such as: stones, broken bricks, glass, etc.).
Step 1: First soak the rose seeds in warm water at about 40 degrees. After the water cools, continue soaking for 4-6 hours, then remove the seeds. Soaked seeds germinate more easily.
Step 2: Put the seeds into the soil (note: the soil needs to be loose, breathable, and highly water-retentive). Generally, you can sow 5~8 seeds per container. After germination, keep one stronger plant depending on the growth of the seedlings; after germination, thin the seedlings, keeping 1~3 seedlings as appropriate. After sowing, cover the top of the container with plastic wrap (a plastic bag or plastic film will also do), and prick a few small holes in the plastic wrap for ventilation. Place the container in sunlight and maintain a temperature of around 20 degrees. Most seeds can germinate after one week; after germination, wait until the seedlings are sturdy, then transplant them into the ground.
