Thanx very much gentlemen for the advice. I wish i had a bigger shed (just builit it last fall)as i'm forced to keep some of my potensai on shelves given the limited floorspace in the shed itself. the picture doesn't do justice to the amount of potensai in front there that i have to cram in the shed. maybe i'll try something of a liner or frame for the shelves to put the pots in and fill with mulch
??
thanx again.
