Can you replant mini rose's outside?

Answer 1

yes you can usually best in a full sun location. They will likely come back year after year.

Answer 2

Miniatures, even those from the grocery store do very well in the garden. As roses, they need full sun and good humidity. Houses are often to dry in the winter. Mini roses given as gifts will do best if transplanted outdoors. Roses do best if allowed a winter dormant period rather than kept at flower production year round.
I currently have four unnamed miniature rose plants people have given me through the years. I also grow a few from Ralph Moore's http://www.sequoianursery.biz/ (Look at his halo series Hulthemia persica hybrids.)
Most minis are not grafted, colder climate gardeners don’t need to worry about mulching the graft and gardeners in warmer climates won’t need to be concerned about suckers from the root stock.
Prune out winter die off once the plant shows new growth. Remove anything dead then prune for shape. Feed the same as you would your other roses just less. At leaf break, before flowers and once after flowers. Valentine's, Memorial, & Labor Day are rough reminders of when to feed.

Answer 3

Also it's good to have a western wind break of some kind, either a wooden fence or a porch steps or building or even build a stone wall just for it. It helps to protected it from the harsh winds and Coldest temps.

Answer 4

Yes, you can, treat them like regular roses.I've had some in the ground for years.
