My hubby built me a new raised bed for my iris. I have to "import" something to fill it with. My choices are:
TOP SOIL (sandy loam)
DOUBLE MIX (topsoil + compost)
TRIPLE MIX (topsoil + compost + sand)
What would you use?

|I don't know which choice is best. The soil I used in my raised beds is described as "sandy soil, composted organic matter and composted manures" and my irises love it.|

|I'm making new beds, not raised but using as much compost as I can afford. It's very rich however so I would go with the triple mix with the sand to make sure it's not too heavy or compacts easily. I have been planting "high" and will be hilling my iris in my beds to keep them from sinking down, amending the hills with some sand/perlite if I need to. I'm not planting till later though so I have some time to figure out.|

|I was wondering if many use sand in their iris beds? I have a heavy clay that I like to add compost to, but never have used sand. We can have lots of rain so I try to hill them up a bit above the flat surface to help combat rot.
