Can roses also be propagated by seeds?
An introduction to the aspect of green plants and flowers about propagating roses by seeds, the specific content is as follows:
Many rose enthusiasts may not know that roses can also be propagated by seeds. In fact, besides cutting and grafting, roses can also be propagated by sowing seeds.
However, seed propagation tends to make the flowering characteristics less stable, for example, a red double variety may turn into a pink semi-double variety after sowing.
Because seed propagation is a sexual reproduction, the genes come from both the male and female parents, so this method is often used to cultivate new varieties. But it's also fine for rose enthusiasts to try it for fun. Let's introduce the sowing method of roses.
Rose Seed Propagation Method - Sowing roses is actually quite challenging, requiring not only patience and carefulness but also a bit of luck.
Rose seeds germinate very slowly, sometimes taking three to four months to sprout. Moreover, the germination rate of rose seeds is very low, less than 30%, so when buying seeds, try to choose plump ones and sow more.
To improve the germination rate, the seeds should be treated first by washing them clean with water and then soaking them in streptomycin solution for an hour to prevent the seeds from rotting during the germination process.

Under normal temperature, rose seeds cannot germinate, so they need to be cold stratified before sowing. Mix the soaked seeds with moist sand, then place them in a plastic bag and put them in the refrigerator's crisper drawer for about a month before sowing.
When sowing, the thickness of the soil covering the seeds should be about 1 cm. Don't cover them too thickly, or it will be difficult for the seeds to break through the soil, and if the soil is too thin, it can easily dry out. After sowing, it's best to cover with a film to keep the temperature and humidity.
Patience is required for 1 to 4 months, after which the seeds will germinate one after another. Generally, after germination, the young shoots will grow within one or two weeks. After germination, it is important to provide sufficient light, preferably more than 6 hours of sunlight a day, to make the young rose plants grow strong.
When the rose seedlings have grown 6 true leaves, they can be transplanted into appropriately sized pots to establish roots first. Some seedlings may grow flower buds early, and these should be pinched off to prevent excessive nutrient consumption, which can cause the young rose plants to become stunted.
Sometimes, rose flowers propagated by seeds can be disappointing, but with luck, you might also get a very good new variety. Enthusiasts interested in roses might as well try it.
