EXPERIMENTS IN TREATING ROOT INJURED NURSERY STOCK. 
The college nurseries furnished abundant material for experimentation. It 
was determined to try the effect of cutting back the trees with different 
degrees of severity. The trees selected were three year old root grafts. 
Each lot included one hundred trees made up of an equal number of five 
varieties, Ben Davis, Longfield, Good Peasant, Lead, Antonovka. 
Apples . 
Lot 1. All branches including leader cut back one-lialf their length; in 
other words, severely “headed in.” 
Twenty per cent grew. This is a larger number than was obtained by 
any other method. The growth was generally weak and spindling. 
Lot 2. Side shoots all trimmed back. The tree left in the form of a whip. 
Of this lot seventeen per cent grew, but with few exceptions the growth 
was feeble. 
Lot 3. Side branches trimmed off. Leader cut back to a height 2-3 feet. 
Of this lot twelve per cent grew, half of them making a vigorous growth. 
Lot 4. Trees cut down to within four inches of the ground. 
Fifteen per cent grew of these. Eighty-five per cent made a growth of ten 
to thirty inches. 
Lot 5. Not trimmed. 
Ten per cent remained alive throughout the summer, but made very feeble 
growth. 
It would appear that a severe heading back gave the best results. 
Plums on Native Stocks. 
Lot 1. Side branches cut back half their length. 
Eighty-five per cent grew; growth uniformly strong, 26 to 36 inches. 
Lot 2. Side shoots cut back to main stem; leader not cut back. 
Ninety-five per cent growing; 20-30 inches. 
Lot 3. Side shoots trimmed off, leader cut back. 
Ninety-two per cent growing. Growth 3 to 4 feet. 
Lot 4. Cut back to ground. 
Ninety-two per cent growing. Growth 2-3 feet, but weak, slender and 
spindling. 
Lot 5. Not trimmed. 
Eighty-three per cent growing. Growth 15 to 20 inches. 
In the case of plums the best trees were obtained by cutting the trees 
back to straight sticks two to three feet in height. Cutting back to the 
ground is to be discouraged very decidedly as the method tends to produce 
an unsalable nursery tree. When cut low they do not sprout promptly and 
growth is likely to be continued abnormally late. 
BANKING. 
The effect -of banking or hilling up root injured nursery trees was tried. 
The banking was done by turning the wings of the cultivator so that they 
would throw the soil against the row. The object in view was to encourage
