Transpiration sliould be reduced by sheltering the cut- tings from the direct rays of the sun. Movable screens placed over the bed during sunshine, and removed at other times, are preferable to whitening the glass, as the latter causes too much shade when the sun is not shining. Damping off, a much-dreaded disease causing cuttings to rot at the surface of the bed, is promoted by excessive heat, over-watering, or insufficient light or air; also by decom- posing organic matter in the material of the bed. Affected plants should be promptly removed and the cause of the trouble should be sought out and corrected. 379. Qreen Cuttings should be Potted as Soon as Roots are formed, which may be detected by their foliage assuming a bright green color. Thej' should first be placed in small pots, and, until they have commenced growth in these, should be treated precisely as before they were pott«d. Propagation by green cuttings includes three divisions, of which the requirements differ in some respects, viz., by cut- tings of h^rhaceoiLS plants, of woody plants (381), and of the leaf, or parts of the leaf, {leaf cuttings) (382). 380. How to Make Green Cuttings of Herbaceous Plants. Roots develop most readily from the younger and more suc- culent parts of the stem, in herbaceous plants. Bend the shoot Fig- 100.
