Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 1946. Too deep. 1947. Too high. 1943. Pot too full. 1949. Good. plants while the ball of soil is wet; it should be dry enough to crumble readily to the touch. Never shift into dirty pots; it will pay to clean them, especially the inside. Never shift a pot-bound plant without loosen- ing the soil on the surface of the ball. A few smart raps with the closed fist will do it; or better still repot as now described. Repotting is necessary frequently when plants have become pot-bound, or when from any cause they appear to require it; such, for instance, as debility from over- shifting, over-watering or neglect of any kind. In such cases the soil should be washed from the roots almost entirely and the plant put into a pot a size or two smaller than it has been growing in, taking care to firm the soil well, and if a shrubby plant prune it back according to its needs and condition. Shade such plants until danger of wilting is past and water spar- ingly until new and vigorous growths appear, showing that the subjects have regained their normal health. There are a few cultural details intimately associated with potting which may with profit be added as a closing paragraph. The high, narrow pot shown on the extreme right of the line of pots in Fig. 1937 is fre- quently used for roses and palms by some, especially for Cocos Weddelliana, which makes a long tap-root and which it is almost invariably fatal to break. It is feasible, however, to avoid this if the seeds are sown in 6-inch pots, using 4 inches of clinkers as a bottom. These check the downward growth and induce develop- ment of fibrous roots in the soil, so that the tap-root may be cut off below them and the ordinary 2-inch pot used with
