The above information is to be used only as a guide. Less vigorous varieties will have to be planted closer than more 
vigorous ones, regardless of the rootstock. Soil types and planting sites will also cause different varieties and clones to grow 
at different rates. Find the desired number of trees per acre by multiplying the distance between the rows by the distance 
between the trees in row and dividing the results by 43,560.
