left to develop spurs ; but if it is of the type with poorly developed eye an-^l of 

 light groM^th it can be removed, leaving the spur. This will then behave 

 like the fruiting shoot previously described, and its later treatment will be 

 similar. If the secondary lateral is of strong growth it is better to leave^a 

 short length, when it will behave as the primary lateral did, and the next 

 season can be brought back to the new spur that has formed. 



As the trees get older and give up their heavy growth, the laterals will be 

 lighter and when cut back (especially on the lower part of the tree) will not 

 make long shoots again, but spurs or fruiting shoots, the management of 

 which is easier. While the trees are young and making very vigorous laterals^ 

 the formation of spurs can be precipitated by shortening the laterals hard 

 during the latter half of the summer. 



Scions. 



Where grafting scions are required for working in the spring they should 

 be collected du.ring pruning from well-grown trees that have hitherto given 

 regular crops of a good type of fruit. 



Spraying. 



With the exception of the early-starting peach trees, such as Bell's 

 November and Edward VII, which should have been sprayed last month, 

 it is now a good time to apply lime-sulphur (winter strength) for peach 

 leaf curl. 



Trees with San Jose scale may be treated now with either lime-sulphur or 

 miscible oil. In bad cases, it would be advisable to give a second application 

 before they start in the spring. 



For mussel scale on apple trees, miscible oil should be used in the pro- 

 portion of 1 to 15 gallons of water, instead of 1 to 25 gallons. If a second 

 application is given, reduce the strength to 1 in 25. 



Apple trees badly affected with woolly aphis should be sprayed with 

 tobacco wash or one of the commercial nicotine extracts. The treatment of 

 trees only slightly afiected may be delayed. 



Codlin Grub Bandages. 



Bandages left on the trees for codlin grubs that have been driver from 

 other resting places by winter rain or cold should be examined and the 

 grubs killed. Any spare time can be usefully employed in the examination 

 of any crevices or loose bark. Codlin and tip moth gnibs found in suck 

 shelter should be destroyed before spring. 



Planting. 



It is still not too late to plant out deciduous trees if the ground is in fit 

 condition. In districts where the ground is still dry and no irrigation is 

 available, it would be better to delay this operation in hopes of further 

 falls of rain.
