Ah, shopping for our dahlia babies! Its almost as much fun as setting up our Baby Nurseries so many years ago, and a whole lot less worrisome! I just ordered from Greenhouse Megastore, that is much easier as we are a ways from any big nurseries here. Your varigated purple rhodies sound lovely! And you have the excuse of hosting the dahlia tour this August so you have to do everything up pretty.
My order was for plant labels, but I bought a bunch of new pots last year so am good on those. I am loving the size of the pots I bought...they are just a little smaller then the ones I was using and I can get 18 in a tray without wedging them in. With my bigger pots I could only get 15 and had to pull the center row up to fit the slanted sides of the pots. These pots are nearly square and a little shorter but so far everything fits.
I also bought a bunch of grow-bags for my veggies...I found that the Grow bag system works wonderfully for setting on top of my heavy clay soil. Much easier then trying to amend that much clay for vegetable garden! I bought a load of organic garden soil and fill the grow bags then set the drip lines along the tops of the bags. This year I am trying 2 of the big potato bags and two shorter ones for carrots and turnips (My son loves baby turnips for snacking). We had the most wonderful crops of tomatoes last year in the grow bags!
Linda, are you continuing to use grow bags for dahlias? I loved that you could move yours to the shade when the heat wave hit.
