Soaking the seeds is a crucial step if your seeds will germinate properly and stay clear of any diseases. You MUST not mix the bleach with the hydrogen peroxide as this results in a chemical reaction. 3% peroxide for 24 hours is just fine. This is also a good time to perform the water float test.
How long does it take to grow a rose from seed? Growing roses from seeds is a lengthy process. Without proper stratification, it can take multiple years for seedlings to emerge. Even the fastest-growing roses will likely take two full growing seasons to produce beautiful blooms.
Now dust the seeds lightly then plant them immediately in the soil. Make sure the seeds are about a quarter-inch deep in the soil. The dusting is to make the surface of the seeds dry to avoid any fungal or mold infections.
By soaking the seed, it enables the new growth from the inside to push through the hard shell and grow. The seeds that could benefit from a good soaking include: corn, pumpkin, beans, chard, beets, and peas. The seeds you shouldn't soak include: carrots, lettuce, radish, celery, turnips, and spinach.
Roses should be planted in native soil, but require good drainage. You can mix some compost or other organic matter with the soil if you have poor, sandy soil or heavy clay. Add 2-4 inches of organic material and mix thoroughly into the garden bed at a depth of 12 inches.
Amazingly, many of these seedlings will flower in as little as 5 to 6 weeks, although some take a full season to bloom. If you like what you see when your seedling does bloom, carefully transplant the new rose into a separate pot. Within three years you should have a fully mature bush and a never-before-seen variety.
Contrary to popular belief, February and March are excellent times to start planting roses. Many landscapers will wait until April and May to begin planting roses because this is when the plants are already in bloom, and many nurseries will get their stock of roses in around January and February.
As a general rule, start three cuttings and expect only one to take. Starting rose cuttings in soil is a more reliable method, as it causes less shock for the plant when you transplant it. This method also encourages the development of hardier, sturdier roots.
Before growing roses from seed, the rose seeds need to go through a period of cold moist storage called “stratification” before they will sprout. Plant the rose bush seeds approximately ¼ inch (6 mm.) deep in a seed planting mix in seedling trays or your own planting trays.
Before planting seeds indoors in a seed tray, water the soil thoroughly so it's moist, but not wet. Then plant the seeds according to the instructions that came with the seeds. You won't have to water after they are planted, preventing seed movement.
Growing Roses From Seed
If you'll be storing them for later planting, place them on an absorbent surface and let them dry off first. Sow them outside, barely covering them. It's best to do this in the fall. The majority of roses need to go through a cold period to germinate.
Rose cuttings take about two weeks to root if they are softwood cuttings. If you are rooting hardwood cuttings, it can take as long as two months before the roots start to develop.
Your rose will most likely reach its full size and optimum bloom production in 3-4 years. Depending on the variety and growth stage at purchase, it will flower in the first or second season. If you're feeling impatient, a vigorous variety in a large nursery pot planted in early spring is the best option.
Roses are generally perennials that can survive in most hardiness zones. Whether or not roses will come back for you every year depends on your hardiness zone. In nearly all zones, roses are perennials and will continue to grow each year.
Leave them for a week or two until they are completely dry to eliminate the risk of spoilage. Store in a labeled plastic bag in the refrigerator or any dark cool place until you are ready to use them. Now you are ready to try your hand at growing new plants.
This structure, called the fruit, is unique to flowering plants. So, the round swelling you see is the ovary of the flower developing into the fruit of the rosebush. When mature, the fruit will hold the seeds of the next generation. We call the fruit of rosebushes hips.
Cut each rose hip open carefully with a knife and dig out the seeds, again placing them in containers with the name of the rose bush they came from. Once the seeds have all been removed from the rose hips, rinse the seeds off to remove any of the pulp from the rose hips still on them.
The correct answer lies somewhere in between: coffee grounds can be beneficial to roses if used correctly. Coffee grounds have antioxidant and antimicrobial properties, which gives nutrients to plants, and as coffee grounds break down in the soil, they suppress plant diseases such as Fusarium wilt.
They're also a good source of potassium, phosphorus, and copper all of which are essential nutrients for roses. Coffee grinds improve the soil around roses by fertilizing and enriching it. Roses require a neutral to acidic soil, and adding coffee grinds will help move the soil pH from neutral to acidic.

The pH of this potting soil is between 6.0 and 6.5, which makes it ideal for growing roses.
