Nut Trees The Linn County Nurseries 

flavor of the wild hazelnuts and in good seasons may be over an inch across. 
The bushes bear when two or three feet high and a single large bush has pro- 
duced over six pounds of nuts. In severe climates the staminate catkins may 
be winter-killed, in which case there would be no nuts produced unless an- 
other hazel of some kind which is a good pollinator is nearby. Farther south 
Winkler is reported as bearing very regularly, and more satisfactorily than 
Filberts. In fall, Winkler foliage is very attractive with scarlet and bronze tints. 
WINKLER PLANTS ARE ALL SOLD UNTIL FALL OF 1943. 
TURKISH TREE HAZEL. 30 feet or more. This hazel grows into a beauti- 
ful tall pyramidal tree which does not sucker. The corky, light yellowish-gray 
bark is very attractive, and characteristically furrowed with age. The foliage 
resembles that of the hazel bushes. The nuts are fair sized and enclosed by 
bracts having curly lacinated tips. This very attractive tree is fully hardy in 
central Iowa but it also is extremely rare. 4-5 ft. trees, $2.00 each. 
GRAFTING WAX. Nut Tree Grafting is usually done later than fruit 
tree grafting and nut tree scions are much slower starting so are often still 
dormant when some very hot weather comes. The waxes commonly used 
break up or separate in such weather and the oil or fat they contain penetrates 
between the scion and stock hindering or preventing a union. After much ex- 
perimenting the U. S. Department of Agriculture has developed a wax which 
does not do this and so gives a much higher percentage of successful unions. 
It is composed only of Rosin, Beeswax, and Kieselguhr and we are pleased to 
offer it at 50c per pound or $4.00 per ten pounds. Postage additional. Try this 
for any grafting and see if it does not greatly increase the success of your 
work, and especially under unfavorable weather conditions. 
THE NORTHERN NUT GROWERS’ ASSOCIATION is an organization of 
progressive people of many different vocations who are interested in the ad- 
vancement of nut culture. An annual report is published which contains the 
most up-to-date practical and scientific information published on the subject 
and is well worth the $2.00 membership fee. All interested in nut trees should 
join. New members will receive both the report of the previous and current 
year. Memberships may be sent to D. C. Snyder, Treasurer, Center Point, Iowa.
