 OBSERVATIONS 



ON 



THE GENERAL MANAGEMENT 



OF 



GREEiNHOUSE PLANTS. 



Having already exceeded my limits, T am compelled to 

 be brief in my observations on such ornamental plants as 

 are generally cultivated in hot and greenhouses. This 

 description of plants embraces those which are collected from 

 various climates, and thrive best in a temperature and soil 

 similar to that in which nature first produced them : hence 

 they who propagate exotic plants, must provide suitable 

 composts, and also separate departments, where the differ- 

 ent degrees of heat may be kept up according to their 

 nature and description. Some of these are raised from seed 

 sown in the Spring, others by layers, suckers, and offsets 

 detached from the old plants, and many by slips or cuttings, 

 planted at different seasons of the year, according to their 

 various natures and state of the plants. Many kinds require 

 the aid of glass coverings and bottom heat, created by fresh 

 horse-dung, tan, &c. See calendar and index. 



Were I to attempt to give directions for the propagation 

 of all the varieties of useful and ornamental exotic plants 

 cultivated in various parts of our country, it would require 

 several volumes. The catalogue of greenhouse plants 

 alone, kept by the enterprising proprietor of the Linnean 

 Botanic Garden at Flushing, occupies fifty pages of close 

 matter; it would, therefore, be impossible to do justice to 

 the subject without dividing upwards of two thousand 

 species of plants into classes, and treating of them under
