TREE AND SHRUB SEEDS. 



PICEA DOUGLASII. 



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 "* 5 C\ 

 this latitude, the seeds should be sown . «^!^vv' 



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 press 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 the birds from destroying 

 them. Seeds of the rarer sorts may be sown 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. 



EVERGREEN TREE SEEDS. 



We do not sell Tree or Shrub seeds in quantities of less than an ounce of any one variety, except 

 those quoted at over twenty-five cents per ounce; of these, twenty-five cent packets may be ordered.
