It can be done all right, as your own observation affirms. The superior
appearance of the trees may be due to the additional water, and
fertilizer probably, used to push the seedlings; possibly also to extra
cultivation given them. It all depends upon what policy is observed in
growing the seedlings; if something more than usual is done for their
sakes, the trees may get their share and manifest it. If not, the trees
will be robbed by the seedlings, and there is likely to be loss by both.
There is no advantage in the mere fact that both are grown; there may be
in the way they are grown. Whether there is money value in the operation
or not depends upon how many undertake it.



Square or Triangular Planting.



What is your opinion on triangular planting as compared with square
planting?



Planting in squares is the prevailing method. The triangular plan is not
a good one when one contemplates removing trees planted as fillers. The
orchard should either be planned in the square or quincunx form. In the
latter case individual trees can be easily removed; in the other case
rows can be removed - leaving the rows which you wish to keep
equidistant from each other.
