them to flower again next winter. Now 

 should they be ))lantecl out in spring 

 with ball, or should earth be shook off 

 from the roots, and should they be cut 

 back when planted out ]

Reply.— r- You will do well to shake 

 the earth out, prune both roots and 

 branches, the roots moderately, plant 

 in good strong soil, and cut off during 

 summer all flower buds that appear. 



SPRUCE TREES. 

 Dear Sir, — Can you tell me what is 

 wrong with my Spruce trees. I enclose 

 a diseased twig. It will cover the 

 whole tree in two or three years, and 

 then the tree dies. What is the 

 remedy? John Sailes.

Reply. — We are not able to say 

 positively what is wrong with your 

 Spruce trees. The twigs sent to us 

 look as though they had been preyed 

 upon by some parasite, such as goes 

 under the general name of mildew^ 

 We suspect that there is something 

 wrong with the soil in which they are 

 trying to grow. Lime rubbish we have 

 found to be very prejudicial to most 

 Evergreens. 



INSECTS ON A PLUM TREE. 



Dear Sir, — T have a Plum tree in 

 my garden known by the name of the 

 Weaver Plum Tree. Last September 

 I noticed that many small black ants 

 were on its branches, afterwards a small 

 worm, about three-quarters of an inch 

 long, of black color, having light streaks 

 on its sides, were observed on the leaves 

 und caused them to wither. I applied 

 a solution of Paris Green to them, but, 



perhaps, it was too strong, for all the 

 leaves withered and fell from the tree 

 shortly afterwards, but it killed the 

 worms. I was afraid the application 

 would kill the tree, but now the tree 

 seems healthy and budding fi-eely, with 

 many blossom buds on it. The ants 

 are also on it, and a small dark grub, 

 or the larvae of some grub, are in large 

 numbers clustered around the stems of 

 the blossom buds. A few of which I 

 have enclosed in a small vial in a tin 

 box for your inspection, which I send 

 to your address through the Post Office. 

 Will you be pleased to let me know 

 what they are, and the best remedy to 

 prevent them destroying the fruit or 

 the tree. Any information you can 

 give me on the subject will be esteemed 

 a great favor, and 



I remain, yours truly, 



W. F. Ross.

Reply. — The insects found on the 

 buds were the black aphis. The ants 

 were numerous because they feed on 

 the sweet liquid exuded by the aphis. 

 Syringing the tree with strong tobacco 

 water will rid it of the aphides. 



PLUM AND PEAR TREES. 



I have a Plum tree named Smith's 

 Orleans, it has been planted about eight 

 years, and borne fruit for two or three 

 years. Last season the bark began to 

 split and part from the trunk of the 

 tree. It has now got about two-thirds 

 round the tree and about three feet up 

 from the ground quite clear of bark. 

 I bound cow manure on last season, 

 thought that might help it, but it was 

 no use. Can you give any remedy for 

 this sort of thing. The fruit all drop- 

 ped off last season when about half 

 grown. I dont expect to save this tree, 

 but may save othei*s if there is any cure 

 for them.
