Need ideas for a rose planting container
I am planning to put a rose in a container to peg (anchor down to the ground so it blooms all along the stem.) I have what should be perfect soil but my roses all suffer when I plant them in it. So I'm looking for a container about 12" high but much larger around so the roots have room. I prefer circular but I'm not stuck on that idea. I would drill holes in it for drainage. Wood deteriorates fast here. What type of thing could I use for this?
