TIME OF SOWING, &c. 



HARDY ANNUALS may be sown in the open border from April to June. Before 

 sowing, which should be done on a fine, dry day, carefully prepare the soil, and, in 

 covering, regulate the thickness by the size of the seeds. Small seeds should be very 

 lightly covered. Success in growing annuals depends in a great measure upon their 

 being properly thiuned to regular distances, so as to give plenty of room for the full 

 developement of each plaDt. This, in too many instances, is entirely neglected ; hence 

 the dissatisfaction so often expressed as to their use. % 



HALF-HARDY AND TENDER ANNUALS may be sown in March and April in 

 shallow boxes, and placed on a slight hot-bed, and, when strong enough, pricked out 

 into a cool frame near the glass, where they may get hardened and well established for 

 transplanting into their blooming quarters in May, or potted off singly for green-house 

 or conservatory decoration. Under ordinary circumstances, most of the varieties will 

 bloom freely if sown in the open ground about the middle of May. 



BIENNIALS AND PERENNIALS.— The more select and tender varieties for Sum- 

 mer and Autumn blooming may be sown in a gentle heat in March and April, and 

 treated in the manner recommended for half-hardy annuals. The hardy kinds may be 

 sown in the open border from April to August, in prepared beds, and when strong 

 enough potted off singly, or transplanted to the open ground, where they are intended 

 to bloom the following year. During the Winter, protect the plants with a light 

 covering of leaves or coarse manure.
