Hi there

I would recommed reading the thread named Saving a Potted Gift Rose as that is the type of mini that one buys at grocery stores. (there are usually 3 plants in a pot) It is not nessessary to plant them in the ground as you can keep them in pots but you need to plant it into a 14" or large pot if you have not already done so. Whether you plant the roses in the ground or repot them into bigger pots they may need winter protection. I do not live in your area so I would not be comfortable to give you advise. Do a search on the regular rose forun on winter protecton and you will find the advise you need.

Remember, and rose is a rose whether it is a mini or a regular size rose. Roses like sun so where you want to plant them sould be ok. But as I said, you can always just repot into a bigger pot so you can keep it on your porch

Good luck, it sounds like you have been doing a good job so far.

I can't keep it on the porch during winter because of freezes. It gets pretty cold here.

I read the topic about the Mini's but I don't remember seeing anything about when to put it in the ground before winter comes.
