The Rhodoree include genera of some of the most singularly ornamental 
evergreen and deciduous peat-earth shrubs that adorn our gardens ; for what 
would our American grounds be without rhododendrons and azaleas? The 
culture of all the species is nearly the same; they all require peat-earth, or, 
at least, thrive best in it; and some of them will not live without it. They 
may all be propagated by cuttings of the growing shoots, planted in fine sand, 
and covered with a glass, or by layers; but the best plants of all the spe- 
cies are procured from seed. The varieties can, of course, only be continued 
by cuttings or layers; and the stools for these require to be planted in beds 
of peat, which should be kept tolerably moist. The seeds, if ripened in this 
country, should be sown soon after gathering ; and those imported from Ame. 
Tica, immediately on being received: because, though the seeds of all the Eri- 
cacez wiil retain the vital principle for several years, yet the longer they are 
kept out of the soil, the less likely they are to germinate, and the greater 
will be the risk of losing some of them. They should be sown in pots or 
boxes, or in a border shaded from the direct influence of the sun; and kept in 
a uniform state of moisture, and protected from the frost. In sowing, the 
surface of the soil should previously be made quite smooth, and gently 
pressed down, or watered till it has settled to a level surface; and, after the 
seeds have been equally distributed over this surface, they should be covered 
with no more soil than is barely requisite to conceal them from the eye. 
Seeds sown in autumn will germinate in the following spring, and be fit for 
transplanting into nursery lines or pots by the autumn, or by the spring of the 
following year. These directions will apply generally to all the species, but 
are more particularly applicable to those which are perfectly hardy. In 
France, some of the species have been increased by herbaceous gratting.
