856 SXPERIMENTAL FARMS 



7 GEORGE V, A. 1917 



Twelve more roots were also dug on November 3, and allowed to remain outside until 

 frozen solid. These were also placed in tlie cellar. The first lot gave very poor 

 returns. The second lot that had been allowed to freeze gave a good crop from Decem- 

 ber 9 until March 1, when roots were removed to make room. Three-year old roots 

 are the best to use for winter forcing. 



ORNAMENTAL GARDENING, 



TREES, SHRUBS, AND HEDGES. 



Trees. — As usual, ornamental trees made a good growth during the season. Insect 

 pests were prevalent on the Experimental Farm, and were also reported from all parts 

 of the province. The larvae of the fall canker worm defoliated a nujnber of native maple 

 trees in the avenues before being checked by spraying with arsenate of lead diluted with 

 water. Later the trees were again attacked by the green aphis which necessitated spray- 

 ing all the avenues and hedges with nicotine sulphate diluted with water. 



Flowering shrubs were badly checked by late springJrosts, and, with the exception 

 of caraganas and a few late lilacs, no bloom was formed. 



Hedges. — There are about thirty specimen hedges on the grounds. These are kept 

 trimmed during the summer in order to show their suitability for ornamental work. 

 Where a low thick hedge is required we recommend the Siberian Pea Tree (Caragana 

 arborescens) , native choke cherry {Prunus virfiriniano), Manitoba maple {Acer Negundo 

 and common lilac (Syringa vulgaris). The blue spruce (Picea pungens), white spruce 

 (Picea alba), and balsam fir (Ahies halsamea) are suitable for a high, close hedge. 



HERBACEOUS PERENNIALS. 



Judging from the large coi*respondence received at this office in regard to horti- 

 culture, the residents of the province are giving more attention to beautifying the 

 home surroundings than ever before. Ornamental trees and shrubs are being planted, 

 lawns established, and perennial flowers set out. The latter, once a bed or border is 

 established, require very little further attention and wliere a proper selection of 

 varieties is made, bloom may be had from May to October.
