All other trees we have we got through Henry Feilds and Gurneys buy one get one free pretty much with their early deals. Blueberries we got from either Lowes or Home Depot were awesome.
I want to try nut trees also, ordering two hazlenuts from Burgees, I think there two for $5.
Early girl tomatoes have done awesome for us. Late blight killed all of them one yr. I use organic liquid copper fungicide now. I buy it concentrated enough for 50gals at Home Depot for the same price as one spray bottle, little bottle is not enough for the amount of plants we have. I use it sparingly, only when it's damp or not drying out good, and remove all dead or spotty leaves. Haven't lost any since I started using it.
