 are most effective on the lawn 1 



1. Planted singly. 



2. Planted in groups. 

 Innerkip. 



M. H. M. 



Peply. — Much depends on the size 

 of the lawn. Maples, Cut-leaved Birch, 

 Maiden Hair Tree, Purple and other 

 Beeches, Catalpa Speciosa, Horse Chest- 

 nut, &c., make handsome specimen 

 trees planted singly, so do the Ever- 

 greens. If the lawn be large, they may 

 be grouped, planting the Beeches, 

 Birches, Maples, &c., in separate groups. 

 The shrubs look best in groups, j)lant- 

 ing the Viburnums in one group, the 

 Weigelas in another, and so on. 



ARBORVIT^: PYRAMIDALIS. 



Please to let me know through the 

 columns of the Canadian Horticulturist, 

 whether the Arborvitse pyramidalis is 

 hardy. Geo. Crawford. 



Copleston, Lambton Co. 



Peply. — We presume that it is per- 

 fectly hardy. We have never heard 

 that this variety is any less hardy than 

 the typical form, which grows far to 

 the northward. Will those who have 



grown it in our colder sections please 

 to give their experience. 



LONDON PURPLE— BARK LICE. 



( I . ) Please say in your next if Lon- 

 don Purple answers as well as Paris 

 Green for Apple, Plum and Peach 

 trees. 



(2.) And what is the best remedy for 

 Bark Licel j^. 



Toronto, 18th April. 



Reply. — (1.) London Purple being 

 of very variable strength is not as safe 

 to use as pure Paris Green. 



(2.) Strong alkaline solutions. Lye 

 from wood ashes, or potash, one pound 

 dissolved in two gallons of water. 



GRAPE VINES. ] 



Allow me to ask the following ques- 

 tions : 



1. Is it desirable to remove the loose 

 bark from grape vines in the spring 

 when putting them up % 



2. Will growing lettuce or other 

 small things around the roots, and thus 

 shading the ground until the berry is 

 formed and partly grown, be an advan- 

 tage? 



Yours truly, 



W. C. Adams, Y.M.C. 

 Toronto, 6th May, 1886. 



Peply. — 1. In the vinery — under 

 glass — it is desirable to remove every- ' 

 thing that will harbor insects. It is 

 not so important in the vineyard. 



2. We can see no advantage what- 

 ever in shading the ground at any 

 time ; would prefer that it should re- 

 ceive the sun's rays without hindrance.
