CHR YSANTHEMUMS. 



given proper care it will continue to 

 grow as if nothing had happened. If 

 it is desirable to grow them in the 

 garden during the summer, they should 

 be hardened to the outdoor conditions 

 by placing them in the open air during 

 the warmer part of the day and protect- 

 ing them during the night, till the 

 ground has become sufficiently warm 

 for them to be placed in the open 

 garden. 



They usually give large blooms, and 

 plants are more easy to handle, if 

 they are grown in pots during the entire 

 summer. When this is done, it will be 

 best to repot them as they need it, till 

 they have been placed into six or seven- 

 inch pots. The pots should be kept 

 plunged into some material, as coal 

 cinders, which will assist in holding the 

 moisture. They can be placed in some 

 protected corner of the garden and 

 plunged into the soil if coal cinders 

 cannot be obtained ; or they are put 

 into a frame and covered with lath 

 screens during the heat of the day ; but 

 they must receive plenty of air and 

 water if good healthy plants are expected 

 The plants should never be repotted 

 after the buds have begun to develop. 

 An application of liquid manure should 

 be made twice a week till the buds 

 begin to open, then it should be dis- 

 continued. A dressing of well rotted 



barnyard manure is often placed on the 

 surface of the soil. 



The plants should be trained from the 

 time they are about six inches high. 

 If the bush form is desired, the top 

 should be nipped off about six inches 

 from the ground and the side buds be 

 allowed to develop ; if only from three 

 to five buds are allowed to remain, the 

 buds will produce large flowers on long 

 stems. If the tree form should be 

 desired, the central stem should be 

 allowed to grow about two feet high ; 

 then the tip should be nipped out, and 

 the lower branches trimmed to the 

 height where it is desired to form the 

 head, and above this the branches 

 should be pinched back whenever the 

 top needs to be made thicker. When 

 the buds are formed, the weak ones 

 should be taken off to encourage the 

 growth of large flowers. 



The plants which have been grown 

 in the garden through the summer 

 should be taken up before the buds 

 begin to form and placed in pots or 

 well drained buckets. The objection 

 to the garden grown plants is that the 

 roots have such a wide range that many 

 of the best feeding roots are lost in the 

 operation of taking up the plants, and 

 thus the plants are reduced in size.

Yellowish Rose Leaves. 



Sir, — I duly received your letter of the 

 20th ult, containing one from Mr. R. Cun- 

 ningham, of Guelph with rose-tree leaves that 

 had turned yellow. Though there was no 

 insect on the leaves, there were under 

 the leaves webs of the minute red spider, 

 which is no doubt the cause of the trouble. 

 Kerosene emulsion sprayed on the plants 

 affected, well under the leaves has been 

 found effectual, also water containing finely 

 powdered sulphur. A treatment which 

 has given good results in California, even 

 on trees, has been fine dry powdered sul- 



phur distributed on the foliage in the 

 morning while the leaves were damp. The 

 roe bushes should at the same time be fer- 

 tilized so as to invigorate them and help them 

 to withstand the attack. 



Without sample of the leaves ot the dying 

 pine trees, it is impossible to speak positively 

 as to a cause. It certainly cannot be the 

 mulching with barnyard manure, but it 

 might be winter killing, as has been the case 

 in other places in Ontario.
