 amount of damage can be estimated. The core se^jms to be most injured and

DTfAPJING EFFECTS OF I/IALLING STOCK S 



Some people have the mistaken notion that all Mailing stocks <exert 

 dwarfing tendencies. That, of course, is not the case. Certain Mailing 

 stocks result in trees of standard size, as for example. Mailing XII. At 

 the other extreme. Mailing VIII results in a tree so dwarfed that it usually 

 must be supported in order to remain upright. This is even more true of 

 Mailing IX. The latter is a very brittle stock but it is preferred to Mail- 

 ing VIII because it is easier to propagate. The following Mailing stock 

 numbers are arranged in approximate order of dv;arfing! 



Very dv;arfing: VIII, IX 

 Semi-dwarfing: VII, II, III, V, IV, I 

 Standard or near standard: X, XIII, XV, XVI, XII

HEAVY BQR.^ APPLICATIO II MAY CAUSE INJ ITRY 



Apple trees are known to be quite resistant to boron toxicity. 

 Yet experiments in Hew Hampshire shav that it is possible to injure trees 

 by excessive soil applications of Borax. Im application of 5 lbs. per 18- 

 year-old tree v;as as much as was safe. Applications of 10 and 20 lbs. 

 caused injury. Trees on soils that have been liiaed will stund more borax 

 than those on soils that have not been limed. If one k-^eps borax applica- 

 tions within the recommended amounts of not over 2 lbs. per tree, there is 

 no danger of injury. (Proc. Amer. Society for Hort. Science, Vol. 43, page 21)

17e are interested in knowing what has been done or is 

 being done concerning the correction of magnesium de- 

 ficiency in Massachusetts apple orchards. We would 

 appreciate it if grov/ers having a magnesium problem 

 would drop us a line, — L. Southv;ick and J. K. Shaw
