AZALEA
, a genus of popular See also:hardy or greenhouse See also:plants, belonging to the See also:heath See also:order (See also:Ericaceae), and scarcely separable botanically from See also:Rhododendron
.
The beautiful varieties now in cultivation have been bred from a few originals, natives of the hilly regions of See also:China and See also:Japan, See also:Asia See also:Minor, and the See also:United States
.
They are perhaps unequalled as indoor decorative plants
.
They are usually increased by grafting the See also:half-ripened shoots on the stronger-growing kinds, the shoots of the stock and the grafts being in a similarly half-ripened See also:condition, and the plants being placed in a moist See also:heat of 65°
.
Large plants of inferior kinds, if healthy, may be grafted all over with the choicer sorts, so as to obtain a large specimen in a See also:short See also:time
.
They require a See also:rich and fibrous See also:peat See also:soil, with a mixture of See also:sand to prevent its getting See also:water-logged
.
The best time to pot azaleas is three or four See also:weeks after the blooming is over
.
The soil should be made quite solid to prevent its retaining too much water
.
To produce handsome plants, they must while See also:young be stopped as required
.
Specimens that have got leggy may be cut back just before growth commences
.
The lowest temperature for them during the See also:winter is about 350, and during their See also:season of growth from 550 to 65° at See also:night, and 750 by See also:day, the See also:atmosphere being at the same time well charged with moisture
.
They are liable to the attacks of thrips and red spider, which do See also:great See also:mischief if not promptly destroyed. rr
The following are some well-known See also:species:—A. arborescens (See also:Pennsylvania), a See also:deciduous See also:shrub 10-20 ft. high; A. calendulacea (Carolina to Pennsylvania), a beautiful deciduous shrub 2-6 ft. high, with yellow, red, See also:orange and See also:copper-coloured See also:flowers; A. hispida, a See also:North See also:American shrub, 10-15 ft. high, flowers See also:
