TREE AND SHRUB SEEDS. 



HOW TO GROW THEM. 



In order to preserve seeds of Conifers and other Evergreen Trees, it is best to keep them in perfectly 



dry sand until the time of sowing. For this latitude, the seeds 

 should be sown thinly, as early in the spring as the ground can be 

 worked, in beds of fine, sandy loam. Cover to the depth of about 

 the thickness of the seed, and rress the beds gently with the back 

 of the spade to firm the earth around the seeds. Great care must 

 be taken not to give too much water, as the young plants damp 

 off very easily. Water with a very fine rose, but never so that the 

 ground becomes soggy. Some shade must be used to protect the 

 young plants from the hot, drying sun and winds, and also to keep 

 she birds from destroying them. Seeds of the rarer sorts may be 

 town in cold-frames or boxes ; if in cold-frames the sashes should 

 be shaded and the frames raised at the corners three or four inches 

 to allow the air to circulate freely. Keep the young plants well 

 weeded, and allow them to remain from one to two years before transplanting. 



The propagation of Deciduous Trees from seeds is less difficult than that of 

 Evergreen species, a little attention only being required to sow at the proper season 

 to insure success. Acorns, Hickory-Nuts, Chestnuts and Walnuts should be 

 planted in autumn, or kept during the winter in sand or moss. They shrivel up by 

 too long exposure to the air, and many of them lose their power of vegetating. Those 

 seeds with hard shells, like the Locust, Gymnocladus, etc., should be planted in 

 autumn, or placed in boxes with sand and exposed to frost before planting. They 

 may not vegetate till the second year after planting, but if these seeds are received 

 too late in the spring to expose them to the action of the frost, they may be put into 

 a vessel of hot water for an hour or so before planting. American Elm, Silver 

 Maple, and a few other sorts ripen their seeds early in summer, and if gathered 

 and planted soon after they fall from the tree, will make fine plants the same 

 season. The seeds of other Deciduous Trees and Shrubs should be planted from 

 the middle of April to the middle of May, in drills about two feet apart and covered about half an inch in 

 depth, according to size.
