Hello there! i am looking to buy some white pine trees and need a little info, and maybe a contact. first off i am located in ne iowa. I have always liked the aesthetics of white pine trees. these are to be planted near a septic system (approx 25-30 feet away from the drainage portion). first off, if i am correct, does a white pine root system consist mostly of a downward "tap Root" with limited size feelers? next are there different species? the area is approx 100' long the line of these will be located in. i like the idea of the long soft needles, and not a bushy look later on when the bottom branches are cleaned up. if there are nursery guys on here, whats a fair price for something about 3' tall, do you offer a disc. and deliver for an order of like 8 or 10? how about spacing between the trees? i was thinking like 8-10 ft apart. is this reasonable? Thanks!
