TREE AND SHRUB LIST 



185 



BIGNONIA. Trumpet Flower. 



*CUTTINGS. Half mature cuttings of evergreen sorts best placed 



under bell jars to root. 

 *LAYERS. Simple layers used. 



ROOT CUTTINGS IN GREENHOUSE. Of larger rooted sorts. 

 BLACKBERRY. 

 ROOT CUTTINGS. Fall; about thickness of lead pencil. Cut into 2 



to 3 inch lengths. Store in sand or sawdust until Spring. 

 BLUEBERRY. (See Vaccinium.) 

 BROUSSONETIA. Paper Mulberry. 

 SEEDS. The tree is dioecious. 

 CUTTINGS. Hard and half-ripe wood. 

 BUDDLEIA. Summer Lilac. Butterfly Bush. 



SEEDS. Sown under glass in February. Seedlings often grow 6 feet 



in six months. 



*CUTTINGS. Use either soft or hard wood cuttings. 

 BUXUS. Box Tree. Boxwood. 



SEEDS. Very slowly grown from seeds. 



CUTTINGS. Made of late growths taken in Winter, root by Spring; 

 or younger wood may be rooted in Summer. Pot and grow in 

 frames for a season. Marinus Van 

 Kleef describes a method as follows: 



"The best way is to grow them from 

 hard wood cuttings during the early Sum- 

 mer after the growth is settled. It is ad- 

 visable to select twigs of good size. The 

 foliage must be stripped off the lower 

 part of the twig for about 2^ inches, 

 while the bottom must be cut with a 

 sharp knife a clean cut heals quicker 

 than one made with a dull knife. Do 

 not cut off the foliage; stripping the 

 leaves is far better. When stripped, a 

 small piece of bark is torn off the twig 

 where every leaf was. This in j ury quick- 

 ly heals over, and on the cambium so 

 exposed roots form quickly. To promote 

 root forming, press the cutting into the 

 soil almost doubled up. Place the first 

 finger of the right hand nearly in the 

 center of that part of the cutting which 

 is stripped of the foliage. The action 

 of bending the cutting while pressing it 

 into the soil causes the bark to crack in 

 several places on the bent part. These 

 injuries heal very quickly; cambium 

 forms on the wounds and from the cam- 

 bium roots develop. (See fig. 95.) 



"Your frame, of course, must be first 

 prepared ready to receive the cuttings. 

 Many people are of the opinion that it is 

 absolutely necessary to remove the soil 



out of the frame to a certain depth, place Fig. 95. The large roots from the 

 a quantity of manure in the bottom, and lowest point in the bend of the cut- 

 cover the manure with about 8 inches of ting come from the new cambium 

 soil to promote the bottom heat. This layer formed where the bark cracks, 

 is not so, although it is advisable to T he smaller roots above come 

 prepare the frame that way if the cut- ^^H^dtf
