188 PRACTICAL PLANT PROPAGATION 



CARYA. (Hicoria) Hickory Nuts. 



*SEEDS. Sow in November or in early Spring, but keep in moist sand 

 all Winter. Difficult to get roots; use sandy soil. 



GRAFTING. The various Garyas are often grafted on the Butternut 

 or C. cordiformis (amara) which is potted a year previously. Veneer 

 or splice grafts are used. Baltet mentions using terminal bud 

 grafting. After wrapping with twine and waxing, the graft is 

 covered with a bag made of waxed paper. The bag serves to hold 

 the moisture, preventing evaporation from the cion. 

 CARYOPTERIS Blue Spirsea. Verbena Shrub. 



SEEDS. Pick the seeds in Autumn. Sow in February. Pot seedlings. 



*GUTTINGS. Pot plants. Bring into heat in February. Take soft 

 wood cuttings. They bloom by September. 



CASTANEA. Chestnut. Chinquapin. 



*SEEDS. C. pumila Chinquapin. Sow seed as soon as ripe. Squirrels 

 and mice will eat the seed, so protect them. Sow in flats rather 

 than seed bed, or keep in moist sand during Winter, sowing in 

 Spring to avoid the pests. Do not rely on Paragon from seed. 



C. americana. Sow seeds as soon as ripe, or if kept till Spring 

 they must be kept from drying out; if put in glass jar tightly 

 corked they keep nicely. 



GRAFTING. Makes them fruit earlier. The grafting is done in the 

 Spring, but not until trees are about to burst into leaf. Seedlings are 

 grafted by whip grafting. No method meets with satisfactory 

 results. The Chestnut may be propagated on the Oak. 

 CASTANOPSIS. 

 SEEDS. Sow seeds as soon as ripe or keep moist until Spring, then sow . 



CATALPA. Indian Bean. 



SEEDS. Sow seeds in Spring after stratifying during Winter. 



CUTTINGS. Made in Spring; set in nursery rows immediately. 



*GRAFTING. C. Bungei (see fig. 96) and C. bignonioides are budded 

 on C. speciosa, late in season, at height of five to six feet. When 

 grafting use the splice graft in May. When budded, the buds are 

 placed on both sides of the stock. Cut bud sticks early and keeps 

 in cool, damp place until June, when bark lifts nicely. 



CEANOTHUS. New Jersey Tea. 



*SEEDS. Sow in Spring, stratify in Winter. 



CUTTINGS. Either ripe or green wood. 



ROOT CUTTINGS. Made in Autumn, placed in flats of sandy soil to 



root. 

 LAYERS. During Summer. 



CEDRELA. 



*SEEDS. Grow readily. 



CUTTINGS. Hard wood with bottom heat. 



*RooT CUTTINGS. Cut down the growth if the first shoot by this 



method is not straight. 

 CEDRUS. True Cedars. 



*SEEDS. Sow in Spring. Seed is short lived. 



GRAFTING. C. Deodara, the Deodar Cedar, and C. Libani, the Cedar 



of Lebanon, best grafted on seedlings of species or on C. atlantica, 



the Mt. Atlas Cedar. Use veneer graft.
