Plant Study 29 



5. Propagation by division. In the winter secure a rhubarb root, 

 cut it into pieces allowing two eyes to a piece, and plant the pieces in a 

 window-box in the schoolroom. Watch the growth of these pieces of 

 roots. Where does the plant-food that nourishes the plants come 

 from? 



Wrap an Irish potato in moist cotton or sphagnum moss. Keep in 

 a warm place in the schoolroom and watch results. 



Make cuttings of geranium, coleus, begonia, and heliotrope and 

 plant them in coarse sand that is kept moist and warm. When rooted 

 notice the place on the stem where the roots start. From what kind 

 of buds do they start? 



On a field trip observe suckers of red raspberries, stolons of black 

 raspberries, and runners of strawberries. Secure rooted cuttings of 

 these plants and plant them in the school garden. 



Following directions previously given, propagate grapes and currants 

 by simple cuttings, blackberries and raspberries by root cuttings, grapes 

 by layers, black raspberries by tip layers, apples by planting seeds and 

 grafting the seedlings, and peaches by planting pits and budding the 

 seedlings. Also, top-work a few branches of an apple tree by means 

 of cleft-grafts and a peach tree by buds.
