24 One Thousand Questions in Agriculture 



/ pound to 6 gallons spray. It kills the long moss, but the green mold 

 it docs not seem to affect. The trees have been sprayed about one week. 

 Some trees have been sprayed with a i pound to lo gallons solution by 

 mistake. Shall I spray these again zmth full strength, and when? 



You have done enough for the moss at present. Even the weaker 

 solution ought to be strong enough to clean the bark. Wait and see 

 how the bark looks when the potash gets through biting; it will 

 keep at it for some time, taking a fresh hold probably with each new 

 moisture supply from shower or damp air. The spray should have 

 been shot onto the bark with considerable force — not simply sprinkled 

 on. 



Shy-Bearing Apples, 



/ have some apple trees lo and 12 years old that do not bear satis- 

 factorily, but persist in making 5 to 6 feet of new wood each year. If 

 not cut back this zvinter, zvill they be more likely to make fruit buds? 



Yes, probably. Certainly you should try it. You should also 

 cultivate less and slow down the growth. If they then take to bear- 

 ing, you can resume moderate pruning and better cultivation. This 

 is on the assumption that your trees are in too rich or too moist a 

 place. But you should satisfy yourself by inquiry and observation 

 as to whether the same varieties do bear well in your vicinity when 

 conditions are such that slower growth is made. If the variety is 

 naturally shy in bearing, or if it requires cross-pollination, the pro- 

 posed repressive treatment might not avail anything. In that case 

 you can graft over the tree to some variety which does bear well 

 or graft part of the trees to another variety for cross-pollination. 



No Apples on Quince. 



Hozv large a tree will the Yellow BelleAeur apple make if grafted 

 or budded on quince root at the age of 15 years? I have been trying to 

 get some information about dwarf fruit trees, but it is difficult to get. 



No wonder the information is hard to get. The Yellow Belle- 

 fleur will not grow upon the quince at all, or at least not for long. 

 In growing dwarf apples the Paradise stock is used, while the quince 

 is used for dwarfing the pear, and many varieties of pears will accept 

 the quince root which the apple rejects. 



Stock for Apples. 



Do you recommend French seedling stock as greatly to be preferred 

 to that grotvn in this country? 



French seedling stock is generally used because it is graded and 

 furnished in uniform sizes; also, because it can usually be purchased 

 for less than seedlings can be grown under our labor conditions. 

 Locally grown apple seedlings are apt to be irregular in size and, as 

 already stated, cost more than the properly graded imported stock.
