Ron Grist ~ ~ Mined Land <br />323G C Road r ~," ~~ Reclamation Division <br />Grand JJflcti0n, CO 01503 <br />Dear I:r. Grist: <br />After inspection this morning of your orchard (with particular, detailed <br />att~:itien to t!ie one year old J. II. Hale trees), several observation:, can <br />be made. <br />1) Of ttie three sites planted vrith J. H. tale peaches i~ 1937, the site <br />in the northwest corner of the orchard does indeed have the poorest first <br />year yro~rtli and lead nearly all the trees that died last year. <br />2) i!r^ trees in tha': northwest corner (both one year old J. H. Hala and <br />thr. adjacent, maturing Cresthaven peach trees) shoer signs only :f some <br />shothule (Co~meum) infection on the young twig growth fi•om last season-- <br />and evrn that. is no mots than is evident on one-,year-old poach twigs elso:ehere <br />In t!!e U1"C ~li!r(I lJhore reasonably JJOiI ~~rn:". til anJ SUr'/IYJI"7~lle was OhS?rL'i~d. <br />4o ether signs of damage due to diseases, insects, or inaiequate irrigation <br />or ,toed control arr. rresent. ~eRiWa~sl <br />~~1~11bility of poor soil conditions or a rr.p?mit <br />c,, en at that site are extremes unlil:2ly as the adjjacent .^.rest'raven <br />peach trees ~.rere growing soirell prior to l;,st year and since the site had <br />befit ~~lont@.! t0 d7p1C and ,ear for ma.}' y,:arc i~rior to plantir. it to t!.^ <br />J. h'. ilal~ peaches. <br />3) The influence of nursery tree quality and weather conditions on early <br />tree yro~rih r•iill vary from year to year. Tlrc grotivth of file J. H. Hale trees <br />planted in the other two sites in 1907 is reasonable--!gut no ;: outstanJin;. <br />This sugnests tlw t these factors influenc~iny first year tree y,•~:~fth ;aa~ 'r-,ve <br />been less titan ideal in 1787, In that case, an ad iitional stra:s "actor <br />(such as excessive dust) would quite likely hurt tree cro;,~th, possibly even <br />to the point of killing a young *_ree since its reserves are less than those <br />of a more mature, established tree. <br />4) You observed excessive flower sheddin3 in the adjacent three rows of <br />Cresthaven peach trees (immediately to the east of the J. Ii. Hale tree.) <br />to be associated with a heavy dust accumulation on the trees early last <br />season. This is also understandable. f;esearch in Washington state and <br />Virginia found that a heavy dust accu,nulation during bloom or the subsequent <br />
