164 THE NURSERY LIST. 



immersed in water and filled with loam, peat and sand ; 

 also by divisions, which root well in a moist, loamy soil. 



Allamanda. Apocynacece. 



Layers. Shoot cuttings will root well at any time of 

 the year in a bottom heat of from yo to 80. The usual 

 time is, however, in spring, when the old plants are 

 pruned back. Choose the tops of the shoots, retaining 

 two or three joints to each cutting. Place in a compost 

 of sand and peat or leaf-mould in equal proportions, 

 singly, in pots, and plunge the pots in the propagating 

 bed. 



Allium, including Porrum, Schcenoprasum. Liliacece. 



Increased by seeds sown thinly in light soil in early 

 spring. By bulbels, planting them in autumn or spring 

 i to 4 inches deep. See Onion, Leek, Chives, Garlic. 



Allosorus. See Ferns. 



Almonds ( Prunus Amygdalus^ P. Japonicd). Rosacece. 

 The almond is worked the same as the peach and 



apricot. Seedling almond stocks are best, but the peach 



is often used. Apricot stocks are sometimes employed, 



but they are not to be recommended. 



Double-flowering almond will grow from root-cuttings 



if on own roots. Heel-in plants in fall, and buds will 



begin to form in three to six weeks ; then make cuttings. 



Results are poor when cuttings are taken directly upon 



first lifting the plants. See Prunus. 



Alnus (Alder). Cupuliferce. 



Propagated usually by seeds, which are gathered in 

 the fall and well dried. Then they are sprinkled lightly 

 on the ground and covered very thinly. Towards the 

 end of the year the seedlings are planted in rows i^ feet 

 apart, and 6 inches from each other, where they may re- 

 main for two years, after which they can be placed where 

 they are intended to stand. Planting is best done in 

 October or April. They are also increased, but rarely, 

 by suckers, by cuttings and by grafting. 



Alocasia. Aroidece. 



Increased by seeds and divisions, as for caladium. 



Aloe. Liliacetz. 



Commonly propagated by suckers, which spring from 

 the base of the plant. Seeds are sometimes employed.
