Peaches at Port Hope. 



§84. Sir, — Can you give me any information regarding peach trees. I have a few 

 planted on clay soil, but they die down every winter, being winter killed. They, however, 

 «hoot up each spring and grow so as to have a good sized stock. They are planted facing 

 •the south. Can anything be done to make them bear ? 



H. 0., Port Hope. 



The peach will not thrive north of Lake Ontario, and our correspondent 

 Tvill find it impossible to succeed with it at Port Hope, as both tree and buds 

 are too tender to endure the cold of winter. The wood, as he states, is killed 

 back, and, even if the wood endured the cold, the fruit buds would be destroyed. 

 The only possible way by which the amateur might succeed with a special tree 

 would be growing the stock horizontally along the ground in such a way that it 

 might be bent over and entirely covered each winter with earth and lifted up in 

 spring. This plan has been tried successfully with plum trees where the climate 

 was too rigorous for them to thrive otherwise. 



Plum Knot. 



885. SiK, — Kindly let me know a remedy for black knot on plum trees ? 



H. 0., Port Hope. 



The simplest remedy for the black knot is to use the knife freely, cutting 

 away the affected parts as fast as they appear and burning them. Success has 

 always been had by painting the affected parts with kerosene oil. Care should 

 be taken, however, that none of the oil is allowed to touch the healthy portions, 

 as it would be destructive. 



Carnations. 



886. Sir,— Will Carnations live out doors all winter? If so, how should they be 

 protected ? I have potted a couple of plants, do they require much water ?

There are garden varieties of Carnations which are quite hardy and 

 require little or no protection. A mulch of leaves or straw would be sufficient 

 for them. The tender or greenhouse sorts, however, when grown outside for 

 the summer, should be taken up early in the fall and grown in the house. 

 They require frequent watering to keep them free from the red spider, and 

 should be kept as cool as possible.
