Letter to Mike lFulford HortScience, Inc. Deodar cedar trees, 4139 Stanley Blvd. Page 2 At least two branch failures were evident on the northeast side of the crown. Both failures were out from the branch attachment to the trunk. A hanger was present over the east driveway. This could fall to the ground at any time. Tree #62 This 40' diameter tree was the source of most of the failed branches. The base was normal in appearance. The tree had either been topped or lost the central leader at 35' to 40'. As a result, 7 lateral branches sweep upright. Some are more vertical than others. On the west side of the crown, several small diameter branches had poor taper. The very top of the crown was flat-topped, perhaps due to topping. Several horizontally oriented lateral branches arose at this point. In the center of the crown, best seen , ue . �� ru,a�a +agr o - ffrom the east driveway, a vertical stem 7241, ?'! 'tea" " " ' broke approximately 10' above its ' . 4r i ? 3' `; r t' '' point of attachment (Photo 2, red arrow). This stem now lacks any � , branches and foliage. An east-facing `!' � ' lateral branch over the driveway also ,� ;' � failed, leaving a 1" lateral as the only i r r live foliage. There had also been a ;,a ��; failure on a north-facing stem, away rF ,1a " '? � ,. from the attachment. 4. '} Photo 2.

In contrast, the west side was full and dense. Tree#63 Located at the north end of the planter area, this e' , rdt', tree had a trunk diameter of 43'/". Overall tree ti„' t r•. r height was less than trees #61 and 62. The ��P 'r I a r' crown was formed by three upright stems (Photo , k: , ;� ,� soi`,4 3). There was no central leader and the crown a t' " 1° t was flat at the top. Branches in the upper crown ? u were vertical in orientation while those in the . i' .7. �4 lower crown were horizontal or pendant.
