THE CANADIAN HORTICULTURIST. 



flowering buds. It is very easy then for an 

 experienced pruner to %o through some 

 'trimming operations' and ignorantly remove 

 all, or nearly all, the flowering branches, 

 and when spring comes there will be a 

 round-headed example of the work of the 

 pruning shears, minus flowers. All we do 

 in winter is to remove and thin out the weak 

 straggling branches from the interiors of the 

 bushes, as these never carry flower buds, 

 and thereby throw the energies of the plants 

 into the flowering branches. During the 

 growing season a constant watch should be 

 maintained to remove sprouts and suckers 

 from the base of the plants, as nearly all 

 varieties of Lilacs that are purchased from 

 nurseries are either budded or grafted, so 

 that sprouts from the base are almost sure 



to be from the stock and should be promptly 

 removed as soon as noticed. 



Lilacs are frequently attacked and kill- 

 ed by a species of borer. This borer may 

 be slightly reduced in numbers, but there is 

 no real, eff"ectual remedy for this serious and 

 destructive pest, and the cultivator is prac- 

 tically helpless in its presence. They are 

 sometimes attacked by scale or bark lice, 

 for which the best remedy is whale oil soap 

 dissolved in the proportion of two pounds to 

 one gallon of water. This should be rubbed 

 on the branches in winter when the plants 

 are dormant. If, however, the plants are 

 seriously aff"ected, the best plan is to destroy 

 them, thus preventing its spread to other 

 bushes. — Vicks Monthly. 



SPIREA BUMALDA. 



Fig. 2134. Spirea Bumalda. 



This spirea is of Japanese origin, its 

 dwarf habit and comparatively late flowering 

 character making it a desirable shrub for 

 use on lawns. The flowers are produced 

 very freely in large corymbs at the terminal 

 points of the young growth. When first 



open the flowers are of a delicate pink color, 

 changing in a day or two to a lighter shade 

 of mauve pink. The plant shown in the 

 photo has flowered freely every year during 

 July for the past twelve years, frequently 

 producing a few sprays of flowers at inter- 

 vals until quite late in the autumn. The 

 new spirea, "Anthony Waterer " sent out 

 by the association as a premium this spring, 

 belongs to the same class of spireas and is 

 supposed to be an improvement on the var- 

 iety figured in the photo, both in color of 

 flower and habit of growth. The plant fig- 

 ured in the photograph is growing in an 

 open situation fully exposed to the north- 

 west winds, as well as the sun during sum- 

 mer and winter. It has had no protection 

 beyond that given it by the snow which 

 speaks well for its hardiness in this section 

 of Ontario at least.
