Sometime ago someone mentioned that they use a dowel with a nail in each end to spread limbs. Is this good for the tree? Wouldn't it create a wound to the tree? It is a fine idea and frugal and one I would like to use. However I would cut 1/2" square wood stock and use nails in either end. Much cheaper---- If you have axcess to a table saw. Also, my trees have been in the ground 1 year April 1st. How much of what fertilizer should I give them? I am in zone 5. Cant wait to get out there and plant some trees, just hope the snow melts in time. Thanks for the imfo, you Guys and Gals are the BEST!!!
