Planting Rose Bush From Cut Roses?
You have to start with a long stemmed rose and you can do it in Spring or Summer. Plant the flower in the soil; cover it with a big glass jar. Like you get in club size pasta sauce. Keep watering it; do not let the soil go dry, water around the jar do not pick it up. You will get a rose plant; it takes 6 to 8 weeks. I have done it with a very fragrant rose that came in a flower arrangement.
Reply:IMPOSSIBLE...if from a rose flower... that is a flower that you cut for a vase to put into your house.. The ONLY way and I have done it many many times is to go to the rose bush and cut off a branch just below a nodule and put that into water or into dirt that has a lot of water.. the new roots will sprout out from the nodule that you left on the stem
Reply:I've accidently grown a rose from a florist long stemmed rose bouquet. The bouquet looked so pretty even dryed that I left it in the vase but didn't dump out the water. I noticed new growth on one flower stem towards spring so I potted it up and planted it in the garden when I planted out my geraniums. The rose bush grew but didn't make it through our winter. Maybe that rose was not hardy to zone 5. I propagate my own garden roses in summer by bending a flowering branch down to the earth and covering a couple of the leaf nodes with 6 inches with soil then putting a rock on top to anchor (leaving the flowering end uncovered) and leaving it alone. The next spring if there is new growth beyond the rock I have a new rose plant. This is a good way to have own root roses from your grafted roses.
