Trees of formal shape are often wanted by the side of garden walks. They are not more fruitful than bushes, given equally skilled attention for both, and they take a little more time to shape, but there is unquestionably a considerable demand for them. Pears on the Quince stock are more suitable for pyramids than any other class of tree, although Plums and, indeed, Apples and Cherries also, are so grown. Where space only permits of a few pyramids being planted, I advise Pears being chosen, with, perhaps, a couple of Plums.
A pyramid is formed in the first place by shortening a maiden tree as before described, but in the second year a more regular disposition of the branches is aimed at when a choice is made, and the upper side shoots are shortened more severely than the lower ones. A complete illustration of the procedure is seen in Fig. 4.
A, maiden tree: a, point of heading, 13 inches from the ground.
C, shows the tree A a year afterwards: d, leader; e, point of heading 15 inches from base; f side shoots thus originated and forming first tier; g, point of shortening side shoots 9 inches from base.
E, pyramid in third year: j, where to shorten the leader; k, second tier side shoots shortened to 6 inches; l, first tier, not to be shortened; m, spurs.
F, tree in fourth year: n, leader shortened to 12 inches: o, third tier shortened to 6 inches; p, second tier not shortened; q, first tier not shortened; r, spurs.
