|I took clippings of my rose tree and was successful in rooting and planting them. They have been in the ground or in pots for over a year and a half. They look very healthy and have plenty of leaves, but no flowers.|
|There area a number of potential answers to your question. First, of course, is lack of sunshine; roses need 6-8 hours of direct sun in order to bloom well. Secondly, too much nitrogen fertilizer will result in lots of green growth, at the expense of flowers. If neither of these apply, maturity might be a factor - there's not much you can do except to wait for the plant to mature. A final consideration is where on the plant the cuttings were taken. Some roses produce blind stems, that is a stem that will not produce flowers, no matter what you do. These stems often occur on plants and we never even notice them because they blend in so well with the other more productive stems.
If they were my plants, I'd continue to give them good care with the hope that they will eventually bloom.
