Madspinner, I'm sorry, I thought someone would answer you in your zone. A mini really is just a smaller rose. It will grow beautifully outside, that's where they should be grown actually to thrive. I think you'll be pleased, minis are pretty hardy roses. I'm betting this won't be your last either:) I don't know this rose, sorry, just your standard rose care applies. I'd follow the info you were given in the care of your mini though from Uncommon Rose.

I cut the amount of fertilizer I give the minis is the only thing I do different from the instructions on the rose package, those pertain to large roses usually.
Good luck with your mini,
Leslie

I had this beautiful little miniature a few years ago. Unfortunately I no longer have it. But, it's very pretty and I would get it again. I have lots of other miniature roses in pots which I store in our garage over winter. I have found the miniature roses love to grow in containers and do better than in the ground sometimes. Really, its just like growing anything in a confined space, it must not be allowed to dry out and it needs nourishment on a regular basis. During the summer months, I like to watch the pots very carefully and water pretty much on a daily basis. I use a soiless mix to pot them in and add a little organic mix ie: kelp meal, fishmeal, blood and bone into the bottom third of the pot before placing the plants in. That way, once the roots have grown sufficiently to reach the organics it gives them a boost. I then use a slow release fertilizer so that they don't go hungry which can often happen when plants are in a confined space. Watering the pots daily soon washes away fertilizer. The main thing to watch for in containers, is water, food and an open soil mix that won't compact.

Have fun with you mini rose
