Hmmmm. I've heard of putting an asprin in the water for cut roses in a vase but never heard of watering with asprin.

if you try it out let us know
im tempted to try on one of my many minis just to see the results. Im a bit iffy though, im scared it might kill it

I think that the idea of using aspirin is that it will boost the imumune system of the plant, which will help during periods of stress and pests attacks.

Here is a link that might be useful: Aspirin for Roses

I used the Asprin on them, they are still doing great. i think as long as we do not do it everytime we water them it will be alright.

next thing i need to know is how to take care of dormant minis so that they will bloom again next year.

The miniature roses I have in containers are over wintered in my garage. Years ago, when I didn't have indoor space, I dug a hole in the garden soil and dropped the container into the hole, then covered over with a little soil. The roses always survived without any problems. But, it depends on what degree of winter protection your climate zone dictates. If you're a warmer zone, you may not need to go to extreme measures to hold them through winter.

Before my pots are stored in my UNHEATED garage, I spray them soundly with lime sulphur dormant oil cocoction, and so far I'm only bothered slightly with a few aphids before they are retrieved in spring, by which time they have usually leafed out. They are then kept under cover - the house overhang until it is safe to put them out in the elements.
