I'm growing in Zone 5 and my roses are mostly on the shadelses south side.
This area had watering restrictions last year, but by and large I was able
to water once a week. This year it looks as if all watering of lawns and
ornamentals is going to be prohibited from the beginning.

The soil is in fair shape, never great on that south exposure. There is
about 3 inches of permanent organic mulch. I'll use what gray water I can,
but the number of roses exceeds my supply. Any suggestions?
