Knockout rose in a container?

[Matt]

This later this summer I will be preparing some new planting beds that will be ready for planting in the fall. In the mean time, I was given a Knockout rose as a gift, but I don't have anywhere to plant it yet. I only have a few spots that are full sun right now, and they are full. Can I plant this rose into a container, grow it on my deck this summer, then trasplant it this fall into the newly prepared bed?

Any tips for growing Knockouts in a container? Is an 18"x18"x18" container large enough? What type of soil should I use?

If I use a product like MiracleGro with Moisture Control potting mix, do I HAVE to use liquid ferts? Or can I still add in organic granular fertilizers like Epsoma Rose-Tone? any tips would be appreciated, Matt

I kept a Knockout rose in a container for 2 winters before planting it. Black spot is such an issue here that I containerize my roses for a year on the back porch and watch them before planting in the garden.

3 have been moved to the graden, 2 are being analyzed, countless others have been trashed.

Roses need a minimum of 6 hours of sunlight a day, and do not like to be crowded. Otherwise, your plans sound fine.
