The Winning Garden in the St. Thomas Lawn and Garden Competition 



The first prize garden of W. R. Rewbotham, of St. Thomas, Ont., is here shown, 

 botham has developed it in only two years A fuller deecription will be given later. 



Mr. Rew- 



borne on different plants of the same 

 species, the pollen must of necessity be 

 transferred from the staminate flower of 

 one "dioecious" plant to the pistillate 

 flower of the other. After the act of 

 pollination is performed the flowers are 

 covered with the paper sacks, and the 

 operation completed by affixing a small 

 tag- bearing essential data. 



Nearly everyone knows the beautiful 

 Primrose, Primula obconica, a plant 

 commonly grown in a great many 

 homes. I have chosen this plant as an 

 illustration on account of that fact, to 

 show the possibilities of practical plant 

 breeding. 



It is plainly evident from Figure i 

 that great improvement has taken place. 

 The small flower represents the original 

 species ; the medium one, that of an 

 improved variety called gigantea; and 

 the large flower that of a cross between 

 Primula obconica and Primula megasae- 

 folia. Although the flowers of the hy- 

 brid were not larger than tho.se of the 

 variety gigantea originally, this enor- 

 mous size has been attained by selection 

 through several generations, plants pos- 

 sessing the largest flowers having been 

 .selected for seed. Up to date each suc- 

 ceeding generation has given us larger 

 flowers than its progenitor. 



The plant is very floriferous, and the 

 umbellato inflorescences, which are re- 

 markably large and borne on long, rigid 

 stems, measuring in some cases 18 

 inches, are most desirable as cut flowers. 

 In this respect a new feature is intro- 

 duced. Figure 2 speaks plainer than 

 words.

Fall Care of Roses 



Wn. Hoot, 0. A. C, Gnelph, Ont 



Bush roses should have a banking of 

 earth placed around them toward the 

 end of the month, or early in November 

 before hard frosts set in. The earth 

 should be banked up in a conical form 

 eight to ten inches high around the plant 

 and patted down firmly with a spade, 

 so as to pitch off the moisture. Late in 

 November or early in December some 

 straw or strawy manure, three or four 

 inches in depth, should be placed on top 

 of this. This latter covering should not 

 be put on too early. It can be left until 

 the first light snow has fallen. By leav- 

 ing the covering off until late, the wood 

 or growth becomes thoroughly ripened. 



T'^a roses or Hybrid Teas require 

 rather more darfe in prtotectihg them 

 during winter than do hybrid perpetuals. 

 Instead of putting the loose strawy 

 covering over them, it is best to tie 

 the growth up in a bunch rather closely, 

 and then thatch it wiith long straw, 

 binding it around with strong twine. 

 The straw should be put on in such a 

 way as to exclude and pitch off all 

 moisture. Putting dry autumn leaves 



around the plants and then covering them 

 with an inverted sugar or flour barrel is 

 a good method of covering tender roses. 

 This method is, howevet, very un- 

 sightly on a lawn. 



OLIMBINQ E0SE8 

 Climbing ro.ses should be taken down 

 from the trellis they are trained on, and 

 the canes laid down as close to the 

 ground as possible without breaking 

 them. About the end of October is a 

 good time to lay them down. Strawy 

 manure, or straw, may be used for a 

 covering for climbing roses. This 

 should not be put on until quite late in 

 November, for the reasons before men- . 

 tioned. The covering should be about 

 two or three inches in depth. Dry 

 leaves may be used first with a light 

 covering of strawy manure over them to 

 keep them in place. There is some ob- 

 jection to leaves on account of harbor- 

 ing mice. Corn stalks should never be 

 u.sed for the same reason. 



Green pine or spruce boughs make a 

 good covering for roses. A light cover- 

 ing of soil can also be made use of. The 

 latter sometimes causes damage to the 

 canes from the weight, and if the sea- 

 son should be mild and wet, soil often 

 induces mildew, and keeps the canes too 

 green and soft by the exclusion of air, 

 and the retention of too much moisture. 

 Some material that will aff'ord a slight 

 protection, admit air, and help to hold 

 the snow around the plants is the best 

 material for protecting climbing roses in 

 winter. 



Planting Roses 



W. G. McKeadrick, Toronto, Ont. 



November in Toronto, is the best month 

 to plant or transplant roses, as the 

 wood is well ripened and the roots take 

 hold and start off quicker than if planted 

 in April, when most of my planting has 

 been done. If you cannot plant in No- 

 vember, April or even May will give 

 splendid results and lots of flowers if two 

 year old roses are purchased. If budded 

 roses are planted, place the joint from 

 one to two inches below the surface and

Plants should have a rest, and that is 



accomplished by withholding water, 



lowering the temperature in which they 



row and not giving them any stimu-
