Hi Brian: Your situation certainly is a challenging one, tho certainly not impossible. With each of your posts I learn a little more of your surounding. Given what I understand now of all this, Rick's suggestion above is the best route. And even tho you don't have all the things and versatility for growing as I do, the seedlings you grew this summer were beautiful--even looked better than mine, I thought. I think we all enjoy sharing your challenges too; with each one as they present themselves. Remember this too: Lilies are tough cookies--they can take a lot and still survive.
I'm sorry to hear of your medical problem. I certainly hope things go well and that your love and thoughts of lilies will give you many pleasant moments along the way. Your lilies will be there waiting for you and we'll be thinking of you!
