52 CUTTINGS, 
A Cutting of the Lemon-Scented Verbena (Aloysia citriodora,) prepared for putting 
into the ground. 
inches deep, at the top of the pot, to keep the stem dry, and to pre- 
yent it from rotting. The cutting, when prepared, should be buried 
to about the second joint, and two or three joints with leaves should 
be left above the soil. A few leaves to elaborate the sap in the case 
of herbaceous plants, or evergreen trees and shrubs, are essential ; 
for Ihave known very promising cuttings of petunias, which had 
been some weeks in the ground, and which had thrown out abun- 
dance of roots, entirely destroyed by some snails having eaten all the 
leaves; and I am told that the case is by no means an uncommon 
one. Cuttings of delicate plants are generally covered with a bell- 
glass pressed closely on the earth, to keep a regular degree of mois- 
ture round the plants, and to prevent too rapid an evaporation; but 
some cuttings when thus treated are very apt to damp off, and zequire 
to have the glass taken off occasionally, and wiped. Cuttings of 
greenhouse plants, I have been told by practical gardeners, strike 
best when put into the pots as thickly as possible; and as they are 
generally well watered when first put into the ground, if covered with 
a close glass, they will very seldom require any watering afterwards
