Collected stock needs more careful attention than nursery stock. Collected material usually The following is a descriptive memorandum to accompany Plate No. VI.

A

If plants are not to be planted immediately (within three or four days) after the time of arrival, they should be carefully unpacked and "heeled-in," until such time as they can be planted to advantage (See Page 36).

B-L And B-2

The average small tree as it is received from the nursery ought to be pruned before the plant is put in its permanent location. This drawing shows a nursery tree (B-l) with two leaders, and the proper pruning of this tree (B-2) by removing one of the leaders and some of the small branches.

C-L And C-2

Large trees and trees which are difficult to transplant should be root pruned not later than July of the summer previous to the season when they are to be transplanted. Usually the fibrous part of the existing root system (C-l) is entirely removed by the transplanting operation unless root pruning is done (C-I) and the trenches filled with well-rotted compost, thus encouraging the fibrous root system (C-2) close to the trunk of the tree and within the diameter of the ball of earth usually moved with the tree.

D-L, D-2, D-3, And D-4

Hybrid roses of various types are sometimes grown on their own roots without grafting (D-1). Such roses should be transplanted slightly deeper (D-2) than in their original position (D-1). D-3 shows the same bush mounded with a depth of 6 to 8 inches of soil, for winter protection. In transplanting grafted roses the knot formation, indicated by the arrow, where the graft was made should be set about I inch or more below the surface of the soil (D-4). If any suckers develop from below the graft, the soil should be dug away and the suckers cut off close to the stem.

E-L, E-2, And E-3

Trees and shrubs growing at a normal depth (E-1) should be transplanted leaving the surface of the ground surrounding the stem at the same point or slightly below that point in the new location, and the basin for watering such plants should be made as shown in E-2. Plants should never be transplanted at an abnormal depth below the surface of the existing ground or permanently left with a mound of earth around the main stem as shown in E-3.

Plate VI. A knowledge of the various operations involved in the work of correctly transplanting plants is essential for their subsequent normal development. These diagrammatic drawings accompanied by the explanation on the opposite page illustrate various transplanting operations.

has a larger spread of roots than plants grown in nursery rows, and as it has never been previously transplanted or root pruned it suffers more severely through loss of root system. Top pruning must therefore be more severe for collected plants than for nursery material, to offset the greater loss of roots. Collected stock usually requires a longer period in which to become well established in its new location. When the loss in transplanted stock is ten or fifteen per cent., the aver-rage loss in collected stock may be as high as twenty per cent. The usual period required for establishing nursery stock in its new location is two years. The usual period for establishing collected stock may range from two to four years.
