lo Jan., 1912.] A New Lucerne Trouhlc. 65 



As soon as a crop has been removed from a plot, the ground should 

 be well manured and dug over. If any pest, such as aphis or caterpillars, 

 has been prevalent, it would be advisable to burn all crop refuse, to 

 destroy any insects that may remain. 



Seedlings of such crops as cabbage, celery, lettuce, cauliflower, &c., 

 may be transplanted; and seeds of peas, French beans, turnip, cauli- 

 flower, &c., may be planted. 



Keep the tomatoes well watered and fed, pinching out surplus and 

 strong growing laterals. In earl} districts the onion crop will be ripening. 

 In late districts, or with late crops, the ripening may be hastened by 

 breaking down the top. An autumn crop of potatoes mav be planted. 



Flower Garden. 



The lawns, flower beds, and shrubberies will need frequent waterings. 

 Such plants as cannas, delphiniums, perennial phloxes, and penstemons, 

 will require a good water supply. These and similar plants will benefit 

 by a good mulching. 



Much hand work will be of great benefit in the flower garden and 

 borders at this season of the year. Regular hoeings do much to improve 

 the texture of the soil, and to conserve the soil moisture. In shallow and 

 undrained soils, constant waterings will be a necessity, if the plants are 

 to be kept alive ; at the same time, there is alwavs the danger of excessive 

 water in undrained soils. 



Mulching will also be an important work this month. This work will 

 greatly assist the retention of soil moisture ; at the same time, it will 

 greatly reduce the temperature of the soil. Anv material that will ulti- 

 mately be incorporated with the soil in the form of humus is useful for 

 mulching purpo.ses. 



Dahlias and chrysanthemums should be kept growing and in good 

 heart, by watering, light feeding, and mulching. Thev should also be 

 tied to the stakes as the growths extend. 



Pests, such as caterpillars of several species, and red spider, will now 

 shortly appear. For the former, weak sprayings with arsenate of lead, 

 or Paris green, may be given. Wherever the red spider is ob.served. the 

 attacked parts should be cut off and burned. Not only should this be 

 done to the chrysanthemums and dahlias, but also to all plants in the beds 

 similarly affected. Constant waterings will often relieve the plants of 

 this trouble, but the most efficacious miethod is to burn all parts affected 

 as the insect makes its appearance. 



Carnations may now be layered and seeds of pansies and perennial 

 and biennial plants may be sown. A few late gladioli and a few spring 

 iflowering bulbs for early flowering, may also be planted. 



A NEW LUCERNE TROUBLE. 



Downy Mildew {Perouosfora trifoliorum. De Bary). 



C . C. Brittlebank, Assistant to the Vegetable Pathologist . 



Some crowns of lucerne were recently forwarded to the office of the 

 Vegetable Pathologist for examination, and were found to be affected with 

 Downy Mildew. As this disease is evidently a recent introduction, the 

 following notes will be of interest.
