INTRODUCTION 
TO 
THE MONTHLY CALENDAR. 
The object of this Calendar is to assist the memory of 
the gardener, and to show him, at one glance, that he may 
find employment in some of the departments of gardening 
in every month of the year. The figures refer to the pages 
in which farther directions may be found, relative to the 
operations adverted to. 
In page 30 it has been shown, that the directions accom- 
panying our Catalogue may be applied to all the climates of 
the United States, by a minute observance of the difference 
of temperature. 
It may be here observed, that the soil is susceptible of cul- 
tivation three months earlier in the remotest South, than in 
the coldest part of our Northern territory; the Calendar, 
therefore, for March, maybe applied to the middle of Janu- 
ary in the warmest climates, and to the middle of April in 
the coldest ; some exceptions to this rule must, however, be 
taken in the Southern States after the three spring months, 
for the following reasons : 
1. As warm weather at the South is of longer continuance 
than in the North, plantations of those species of vegetables 
denominated tender in the table, page 26, may be made in 
the open garden from March to August. 
2. Extreme heat being detrimental to the cultivation of 
many half-hardy vegetables, such as Broccoli, Cauliflower, 
Cabbage, Celery, Lettuce, Radish, Turnips, &c., these can 
only be cultivated in perfection in spring and autumn, the 
latter crops, therefore, should not be planted till August or 
September. [See note to article Broccoli, page 49 ; also 52, 
72, and 104. 1 v
